Security Cage Installation for Warehouses & Businesses in Sacramento, CA
If your business needs to restrict access to valuable inventory, protect expensive equipment, or create a secured storage area inside your warehouse or facility, a chain link security cage is one of the most practical and cost-effective solutions available. Fantastic Fence designs and builds custom chain link security cages for businesses throughout the greater Sacramento region, including indoor warehouse enclosures, outdoor storage cages, and secured partitions for retail and commercial buildings.
A security cage is exactly what it sounds like — a fully enclosed chain link structure, built to whatever size and configuration your space requires, with a lockable door or gate that limits access to authorized personnel only. Unlike a standard perimeter fence that goes around a property, security cages are typically installed inside buildings or in specific areas where certain items need an extra layer of protection beyond what a locked building door provides.

Why Do Businesses Install Security Cages?
Not everything in a warehouse or business needs to be behind a locked cage. A pallet of cardboard boxes probably does not need its own enclosure. But certain items are high-value, easily stolen, subject to regulatory requirements, or simply need controlled access. The general rule is this: if an item is small enough to walk away with and expensive enough to be worth stealing, it probably belongs inside a security cage.
Common Items Stored Inside Security Cages
- Electronics and technology. Laptops, tablets, phones, servers, networking equipment, and other tech inventory are prime targets for theft because they are high-value and easy to conceal.
- Tools and power equipment. Power tools, specialty hand tools, and diagnostic equipment are expensive to replace and frequently walk off job sites and out of warehouses.
- Automotive parts and tires. Catalytic converters, wheels, tires, and specialty auto parts are commonly secured in caged areas at dealerships, auto shops, and distribution centers.
- Pharmaceutical and medical supplies. Medications, controlled substances, and medical devices often require secured storage to meet regulatory compliance (DEA, OSHA, etc.).
- Alcohol and tobacco inventory. Distributors, restaurants, and retail stores frequently cage liquor and tobacco products due to their resale value and regulatory requirements.
- Sensitive documents and records. Legal files, financial records, and confidential business documents are sometimes stored in caged areas for both security and compliance purposes.
- Machinery parts and components. Expensive replacement parts, motors, pumps, and specialized components that are critical to operations and costly to replace.
- Personal property and tenant storage. Apartment complexes and self-storage facilities use security cages to create individual storage units within a shared space.
The common thread is value-to-size ratio. The smaller and more valuable an item is, the more likely it needs to be caged. A forklift is hard to steal — but the $2,000 battery inside it is not.
Where We Install Security Cages
Our crew builds security cages in a variety of settings. The installation process differs depending on whether the cage is going indoors or outdoors, and what type of surface we are working with.
Inside warehouses and distribution centers (floor-mounted)
This is the most common installation. The cage posts are welded to steel base plates and anchored directly into the concrete warehouse floor using expansion bolts, making the cage a permanent, solid fixture. Indoor cages can be built as freestanding enclosures with walls and a ceiling, or as partitions that divide a larger space into secured and unsecured zones. Floor-to-ceiling cages that extend all the way to the roof deck provide the highest level of security.
Inside retail and commercial buildings
Stockrooms, back-of-house storage areas, server rooms, and supply closets can all be secured with a chain link cage. These installations work the same way as warehouse cages but are typically smaller and may need to integrate with existing walls, doorways, or shelving systems.
Outside on concrete or asphalt
Outdoor security cages are used to protect equipment like HVAC units, generators, transformers, propane tanks, and dumpsters. For outdoor installations on existing concrete pads, we anchor the posts the same way as an indoor installation. For asphalt or dirt surfaces, we jackhammer into the ground and set the posts in concrete footings for a solid, permanent hold. Outdoor cages almost always include a ceiling or top panel to prevent someone from climbing over.
How Security Cages Are Built
Materials
Our security cages are constructed from chain link fencing, the same durable material we use for our commercial and industrial fence installations. We offer two primary finish options: galvanized (silver) chain link, which is the standard and most economical option, and black vinyl-coated chain link for a cleaner, more finished appearance. The chain link mesh comes in several opening sizes ranging from standard 2-inch down to 1/2-inch mesh. For maximum security, we recommend the smaller mesh sizes — they are stronger, harder to cut with bolt cutters, and impossible to climb.
Heights
Security cages can be built to virtually any height. The most common heights are 8 feet and 10 feet for freestanding cages, though we frequently build floor-to-ceiling enclosures in warehouses where the cage extends all the way up to the roof structure. Shorter cages (4 to 6 feet) are sometimes used for countertop enclosures or low-profile partitions, but taller cages with a ceiling panel are always more secure because they eliminate the possibility of someone climbing over.
Walls and Ceiling Panels
We build cages with both wall panels and ceiling panels. An open-top cage (walls only, no ceiling) may be adequate for some applications, but for true security, a ceiling panel is essential. Without a top, someone can climb over the walls or reach in from above with a tool to grab items. We recommend ceiling panels on any cage that stores high-value inventory or is located in an area without 24/7 supervision.
Doors and Gates
Every security cage includes at least one lockable door or gate. We build several door styles depending on the application and the level of access control required:
- Standard hinged swing doors. The most common option. A single or double swing door with a heavy-duty frame, hinges, and a locking mechanism. Available in standard widths (3 to 4 feet for pedestrian access) or wider for forklift and pallet jack access.
- Slide gates. For wider openings where a swing door is not practical, a sliding gate rolls on a track and can span openings of 10 feet or more. Common in warehouse settings where forklifts need to pass through.
- Dutch doors. A door split horizontally into two independent halves. The top half can swing open while the bottom stays closed and locked, creating a service window. This is ideal for tool cribs, parts counters, and supply rooms where employees need to request items from a cage attendant.
- Service windows. A small pass-through opening built into the cage wall, often with a sliding panel or hinged flap. Used for issuing tools, parts, or materials without opening the full door.
Lock Options for Security Cages
The lock on your security cage is just as important as the cage itself. We offer a range of locking options from simple to sophisticated, and the right choice depends on how many people need access, how often the cage is opened, and whether you need to track who enters and when.
Padlock hasp (bring your own lock)
The simplest and most affordable option. We weld a heavy-duty hasp onto the door frame and you supply your own padlock — whether that is a standard Master Lock, a combination lock, a shrouded padlock for extra security, or a Bluetooth-enabled smart padlock. This gives you full flexibility to change locks, issue keys, or upgrade at any time without modifying the cage.
Keyed deadbolt
A commercial-grade deadbolt lock built into the door, just like you would find on a building entrance. Deadbolts provide strong physical security and are a good middle-ground option. Keys can be duplicated for authorized personnel, and the lock can be rekeyed if an employee leaves or a key is lost.
Mechanical combination (keypad) lock
A push-button lock that opens with a numeric code — no keys required. This is popular for cages accessed by multiple employees because you can share a code without cutting keys. If security is compromised, you simply change the code. These are battery-free mechanical locks, so they work reliably without power or connectivity
Electronic access control
For the highest level of security and accountability, electronic locks integrate with your building’s access control system using key cards, fobs, or PIN codes. Electronic systems log every entry with a timestamp and user ID, giving you a complete audit trail of who accessed the cage and when. This is often required for pharmaceutical storage, DEA compliance, and high-value inventory management.

FREQUENTLY ASKED QUESTIONS: HOA FENCES & GATES
How tall should a security cage be?
The most common heights are 8 feet and 10 feet for freestanding cages. For maximum security in a warehouse, we recommend floor-to-ceiling enclosures that extend all the way to the roof deck. Shorter cages of 4 to 6 feet are sometimes used for countertop applications or low-profile partitions, but taller cages with a ceiling panel are always more secure.
What is the difference between a security cage and a warehouse partition?
The terms are often used interchangeably, but a security cage is typically a fully enclosed structure with walls and a ceiling (or top panel), while a partition usually refers to a dividing wall that separates two areas without necessarily enclosing the top. A cage provides 360-degree security including overhead. A partition controls access and visibility but may not prevent someone from climbing over. We build both, depending on
your needs.
What size mesh should I choose for my security cage?
Chain link mesh for security cages ranges from standard 2-inch openings down to 1/2-inch. For general security where you want to prevent unauthorized access but do not need to stop small items from being passed through, 2-inch mesh works well. For higher security where you need to prevent theft of small items, block bolt cutters, and eliminate climbing, we recommend 1-inch or 1/2-inch mesh. The smaller the mesh, the stronger and more secure the cage.
What kind of lock should I put on a security cage?
It depends on your situation. For a simple storage cage accessed by one or two people, a padlock hasp with a quality padlock works fine. For cages accessed by multiple employees, a mechanical combination keypad eliminates the need to manage keys. For pharmaceutical, evidence, or high-value storage where you need an audit trail of who accessed the cage and when, electronic access control with key card or fob entry is the best choice. We can install the hardware for any of these options.
Can a security cage be installed on any floor surface?
Yes. For indoor installations on concrete floors, the cage posts are welded to steel base plates and anchored with expansion bolts. For outdoor installations on existing concrete pads, we use the same anchoring method. For asphalt or dirt surfaces, we jackhammer into the ground and set the posts in concrete footings. The cage is a permanent, solid structure regardless of the surface.
Does a security cage need a ceiling or top panel?
We strongly recommend ceiling panels for any cage storing high-value items. Without a top, someone can climb over the walls or use a tool to reach in and remove items from above. The only situations where an open-top cage may be acceptable are low-value storage areas or partitions used primarily for traffic control rather than theft prevention.
Can you build a security cage with a service window or Dutch door?
Absolutely. Dutch doors and service windows are popular for tool cribs, parts counters, and supply rooms. A Dutch door has a top and bottom half that open independently — staff can open the top to issue items while the bottom stays closed and locked. A service window is a small pass-through opening in the cage wall with a sliding panel or hinged flap.
How much does a security cage cost?
The cost depends on the overall size of the cage, height, mesh size, door type, lock hardware, and whether a ceiling is included. Because every cage is custom-built to fit a specific space and purpose, the best way to get an accurate price is to schedule a free on-site estimate. We will measure your space, discuss your requirements, and provide a detailed written quote.
Can an existing security cage be expanded, relocated, or modified?
Yes. Chain link security cages can be expanded by adding additional panels and posts. They can also be partially disassembled and relocated if your layout changes. We can add doors, service windows, or ceiling panels to existing cages, and we can replace damaged sections without rebuilding the entire enclosure.
