Surface-mounted, semi-recessed, and fully recessed fire extinguisher cabinets for commercial buildings. ADA-compliant installations with wall opening cutting, framing, and finishing — a service most fire protection companies cannot provide.
The mounting type determines how the cabinet sits relative to the wall surface, affecting ADA compliance, installation requirements, and visual profile.
Mounts flat against the wall surface with the entire cabinet projecting outward. Ideal for concrete or block walls, parking structures, and outdoor locations where recessing is not feasible. Protrudes 6 to 9 inches.
Partially embedded in the wall (3.5 to 4 inches deep) with a trim frame projecting approximately 2 inches. The most common interior commercial choice. Can be configured to meet the ADA maximum 4-inch protrusion limit.
Entirely within the wall cavity, flush with the wall surface. Provides 0 to 1 inch of protrusion — the ideal solution for ADA compliance. Best for new construction, healthcare facilities, and high-end interiors.
Recessed installation with a drywall return instead of visible trim — the cabinet opening is finished with drywall for a seamless, flush appearance. A premium architectural choice for upscale commercial interiors.
NEMA-rated sealed surface-mount cabinets designed for exposed environments. Available with break glass or flip-open doors. Engineered for parking garages, loading docks, pool areas, and outdoor corridors where UV exposure, moisture, and temperature swings require a ruggedized enclosure.
The door style affects extinguisher visibility, vandal resistance, and emergency access. Fire inspectors generally prefer full-visibility options.
Clear tempered glass door providing full view of the extinguisher at all times. The preferred choice for fire inspectors.
Maximum VisibilityThin glass panel that breaks cleanly for emergency access. Used in emergency-only applications where tamper prevention is prioritized.
Emergency AccessSplit glass panels (top and bottom) separated by a horizontal bar. Common in semi-recessed cabinet installations.
Split VisibilitySteel or aluminum door with no glass. Requires a “FIRE EXTINGUISHER” decal on the door for identification. Chosen for aesthetic consistency.
Decal RequiredClear plastic door that is shatter-resistant. A vandal-resistant alternative to tempered glass, ideal for high-traffic or vulnerable areas.
Vandal-ResistantCurved acrylic front providing a modern aesthetic with full visibility. Creates a distinctive design element while protecting the extinguisher.
Modern AestheticCabinet material affects durability, corrosion resistance, appearance, and cost. All materials are available across surface-mounted, semi-recessed, and recessed configurations.
The most common and cost-effective option. Durable powder coat finish resists chips and scratches.
Lightweight and corrosion-resistant. Good choice for coastal environments and humid conditions.
Premium material for upscale applications. Naturally corrosion-resistant, ideal for coastal and healthcare facilities.
Heavy-duty option for outdoor and industrial applications. Zinc coating provides long-term corrosion protection.
Matching the correct cabinet to your extinguisher ensures proper fit, secure mounting, and code-compliant installation.

Semi-recessed cabinets require a minimum 3.5 to 4 inch wall cavity depth. Fully recessed cabinets require the full cabinet depth (5 to 8 inches depending on size). Verify your wall construction type and stud depth before specifying recessed cabinets. RPS can survey your walls and recommend the appropriate cabinet configuration.
ADA compliance is the most frequently overlooked aspect of fire extinguisher cabinet installation — and the most costly to get wrong.
Under ADA Standards and California CBC Chapter 11B, wall-mounted objects that protrude more than 4 inches from the wall surface and are positioned between 27 and 80 inches above the finished floor are considered obstructions in accessible routes. Standard surface-mounted fire extinguisher cabinets and wall brackets protrude 6 to 9 inches — well beyond the ADA limit. This means a surface-mounted cabinet in a corridor, hallway, or any accessible route may violate accessibility requirements.
California Building Code Chapter 11B is more restrictive than federal ADA in several respects. More importantly, the Unruh Civil Rights Act imposes a minimum $4,000 penalty per violation in California ADA lawsuits. This makes ADA compliance for fire extinguisher cabinets a significant liability issue, not just a code issue. Every protruding cabinet in a corridor is a potential claim.
As a building specialties company, RPS can cut wall openings, frame for recessed cabinets, and finish drywall — something most fire protection companies subcontract out. We handle both fire code compliance and ADA compliance in a single scope of work, eliminating coordination between multiple trades. Whether you need a new semi-recessed installation in a tenant improvement or a full ADA upgrade across an entire building, RPS manages the complete process from survey to finished installation.
We supply fire extinguisher cabinets from the industry's most specified manufacturers, with product lines to match every budget and architectural requirement.
UV-resistant covers extend the life of extinguishers in exposed outdoor installations where a weatherproof cabinet is not required or practical.
Red vinyl or polyethylene covers with “FIRE EXTINGUISHER” text to maintain visibility while protecting the extinguisher from UV degradation, rain, dust, and temperature extremes. Available in sizes to fit 5 lb, 10 lb, and 20 lb units.

Common questions about fire extinguisher cabinets answered by our building specialties team.
The semi-recessed fire extinguisher cabinet is the most popular choice for commercial buildings. It partially embeds into the wall cavity (typically 3.5 to 4 inches deep) with a trim frame that projects about 2 inches from the wall surface. This configuration offers a clean, professional appearance while meeting ADA protrusion limits when properly installed. JL Industries Ambassador and Cosmopolitan series, Potter Roemer Alta, and Larsen's Architectural series are among the most commonly specified semi-recessed cabinets in commercial construction.
Yes. Under ADA Standards and California CBC Chapter 11B, wall-mounted objects that protrude more than 4 inches from the wall and are mounted between 27 and 80 inches above the finished floor are considered obstructions in accessible routes. A standard surface-mounted fire extinguisher cabinet protrudes 6 to 9 inches, which violates this requirement. Solutions include semi-recessed cabinets configured to 4 inches or less protrusion, fully recessed cabinets that sit flush with the wall, or surface-mounted cabinets with cane-detectable guards. In California, the Unruh Civil Rights Act imposes a minimum $4,000 penalty per ADA violation, making compliance a significant liability concern.
A semi-recessed cabinet is partially embedded in the wall, typically 3.5 to 4 inches deep, with a visible trim frame that projects about 2 inches from the wall surface. It requires a smaller wall opening and works well with standard drywall construction. A fully recessed cabinet is entirely embedded in the wall cavity so that the door sits flush with the wall surface, providing a completely flat profile with zero to 1 inch of protrusion. Fully recessed cabinets require a deeper wall cavity and are best planned during new construction or major renovation. Both types meet ADA protrusion limits, but fully recessed cabinets are preferred in healthcare, high-end, and high-traffic environments.
Yes, but the installation method differs from drywall. In concrete or block walls, surface-mounted cabinets are the most common choice because recessing into concrete or CMU block requires core drilling or saw cutting, which is more labor-intensive and costly. For new construction with block walls, recessed cabinets can be planned into the wall layout before the block is laid. RPS Building Specialties handles both surface-mounted and recessed installations in all wall types, including concrete, CMU block, and drywall.
The most common door styles are full glass, break glass, vertical duo (split glass panels), solid panel, acrylic or polycarbonate, and bubble (curved acrylic). Full glass doors provide maximum visibility and are preferred by fire inspectors because the extinguisher is immediately visible. Break glass doors are used in emergency-only applications. Solid panel doors require a fire extinguisher decal on the door and are chosen for aesthetic reasons. Acrylic and polycarbonate doors offer shatter-resistant alternatives to glass, making them ideal for vandal-prone or high-traffic areas. Your choice depends on the facility type, inspection requirements, and aesthetic preferences.
