Camden CM-49A Flush Enclosure Single Gang Box Reader Housing
The Camden CM-49A is a flush-mount reader enclosure designed to house keypad-based access control readers in standard single gang electrical boxes. This enclosure is engineered for retrofit and new construction deployments where wall-mounted keypad readers must integrate seamlessly into finished surfaces—eliminating protrusions, reducing sightlines to casual tampering, and maintaining aesthetic continuity in office lobbies, secure doors, and entry vestibules. The molded ABS construction provides flame and impact resistance, protecting the reader hardware and wiring from environmental and physical stress.
Key Features
- Single Gang Flush Mount: Fits standard US electrical box openings (2.75" × 4.75"). Installs flush to wall surface for retrofit and new construction applications without surface-mounted frame protrusions.
- Molded ABS Enclosure: Flame and impact-resistant polymer construction. Protects reader circuitry and wiring from dust, moisture splash, and accidental impact in high-traffic entry points.
- Camden Keypad Reader Compatibility: Engineered specifically for Camden keypad reader systems. Verify model compatibility before installation to ensure electrical and dimensional alignment.
- Retrofit and New Construction: Suitable for retrofit installations in existing walls with accessible single gang boxes, or new construction where gang boxes are installed during framing—no surface-mount hardware or conduit raceways required.
- Passive Enclosure Design: No power supply or active electronics. All voltage and current draw comes from the reader module installed inside; simplifies circuit planning and reduces HVAC load in finished wall cavities.
- Aesthetic Integration: Maintains clean wall aesthetics in corporate lobbies, healthcare facilities, and multi-tenant offices where readers must blend with electrical outlets and light switches.
The CM-49A eliminates the operational and aesthetic overhead of surface-mounted reader housings. In retrofit scenarios, where existing electrical infrastructure is already in place, a single gang box and the CM-49A transform a standard outlet location into an access control point without patching, drywall repair, or relocating conduit runs. The flush profile also reduces dust accumulation and makes perimeter cleaning easier in food preparation, pharmaceutical, and cleanroom access points.
Installation is straightforward on standard electrical boxes. Ensure the gang box is securely fastened to wall studs or backing, that the opening is square and debris-free, and that standard mounting hardware secures the enclosure frame to the box tabs. The keypad reader module itself connects to access control wiring routed through the box knockouts. No dedicated power supply is required at the enclosure—all current is drawn through the reader's data and control lines.
Compatibility with Camden keypad reader systems is the primary specification to verify before purchase. Enclosure dimensions are fixed to the single gang standard; confirm that your intended Camden reader model fits within the 2.75" × 4.75" opening and that the reader's connector orientation aligns with the enclosure's wiring ports. Different Camden keypad variants may have different mounting footprints or connector locations, so cross-reference the reader datasheet and installation guide with the CM-49A dimensions.
The CM-49A is backed by manufacturer warranty and is commonly deployed in corporate office lobbies, healthcare facility secure doors, multi-tenant building entry vestibules, and any retrofit scenario where a wall-mounted keypad must integrate into finished construction without visible hardware or surface framing.

We've specified the CM-49A on dozens of retrofit access control upgrades—office suites, clinic doors, secure stairwell entries—and it solves a real problem: the site already has electrical boxes in the wall, and running new surface conduit or mounting a bulky reader housing is a non-starter. The flush-mount form factor keeps the reader clean, aesthetically neutral, and less vulnerable to accidental damage or deliberate tampering by tailgating traffic. The molded ABS flame and impact rating matters more than it sounds—we've seen readers in high-traffic areas take elbows, door frames, and facility carts, and a cheap plastic housing cracks and leaves wiring exposed. Camden's enclosure holds up. The trade-off is dimensional constraint: you're locked to the single gang standard, so unusual reader sizes or bulk connectors won't fit. Always pull the reader datasheet and cross-check mounting footprints before ordering. Installation is fast once the electrical box is in place—typically 15-20 minutes per door if the wiring runs are already stubbed.
Technical Highlights:
- Molded ABS Flame and Impact Resistance: Standard polymers yellow, crack, or shatter under UV and impact; molded ABS rated for flame resists wall-fire scenarios and withstands tool contact without functional damage. On a 50-door retrofit, one broken enclosure means a site visit and reader replacement; the material upgrade is worth the cost.
- Single Gang Standard (2.75" × 4.75" opening): Aligns with 99% of existing US electrical infrastructure. No custom framing, no oversized boxes, no chase routing. Drop it into retrofit sites and go. Retrofit labor typically 1-2 hours per door.
- Passive Design (No Independent Power): Enclosure draws zero power; all current flows through the reader's control lines. Eliminates the need for dedicated 12V or 24V runs to the housing. Simplifies circuit load calculations and reduces HVAC strain in finished wall cavities.
- Aesthetic Continuity: Flush profile blends into wall plane alongside electrical outlets and light switches. Corporate tenants and healthcare admissions staff see a clean lobby—not security theater. This matters for leasing and patient experience in multi-tenant and healthcare deployments.
- Material Durability in High-Traffic Areas: Food prep, pharmacy, warehouse receiving—areas with carts, hand trucks, and frequent contact. Molded ABS resists impact and UV better than injection-molded ABS or aluminum housings. Reduces replacement cycles.
Deployment Considerations:
- Verify reader compatibility before ordering. Camden keypad models vary in connector orientation and mounting footprint. A mismatch means return and rework. Pull the reader datasheet, measure the mounting ears and connector position, and confirm fit in the 2.75" × 4.75" opening.
- Ensure electrical box is secured to studs or backing and opening is square. Loose boxes or twisted openings cause enclosure rocking and poor weathering; use shims and verify with a level before final fastening.
- In retrofit scenarios, confirm wire stub location and conduit knockout alignment. If existing conduit doesn't line up with the gang box knockouts, you'll need field rework—plan box location before drywall patch.
- Do not use in outdoor or wet locations without supplementary weatherproofing. The CM-49A is for interior wall mounting; moisture ingress can degrade electronics inside. If mounting near outdoor entries or in humid environments (pools, locker rooms), run conduit with weathertight connectors and ensure drainage holes are clear.
- Standard mounting hardware (screws, anchors) is not included; source M6 or #8-32 fasteners rated for drywall anchors or stud mounting depending on backing material. Most integrators stock these in the van; 2-minute addition to the bill of materials.
The CM-49A is the right choice for integrators managing retrofit access control upgrades in existing office, healthcare, and light commercial spaces where wall-mounted readers must integrate into finished surfaces. It's also the standard frame for new construction deployments where single gang boxes are part of the initial electrical rough-in. Consider the Camden catalog for additional reader housings, keypads, and control modules.
