Camden CM-PT375SS-24 Stainless Steel Endcaps 24"

Camden CM-PT375SS-24 Stainless Steel Power Transfer Cable Endcaps

The Camden CM-PT375SS-24 is a stainless steel power transfer cable assembly designed for access control and door activation systems operating in corrosion-prone environments. This 24-inch endcap assembly carries up to 16 conductors of 22-gauge wire (or 8 conductors of 18-gauge) through a protective 3/8" ID housing, eliminating the oxidation and maintenance cycles associated with aluminum or zinc-plated alternatives. Stainless steel delivers measurable lifecycle cost savings in loading docks, coastal installations, exterior vestibules, and any threshold where salt-air or persistent moisture would degrade conventional finishes within 3–5 years of service.

Key Features

• Stainless Steel Construction: 304-grade or equivalent — zero oxidation, discoloration, or finish degradation over 10+ years in salt-air and wet environments. Eliminates replacement cycles and finish-restoration downtime.
• Wire Capacity: Accommodates 16 conductors of 22-gauge wire or 8 conductors of 18-gauge. Match conductor gauge to your load profile to ensure safe power delivery without voltage drop.
• 24-Inch Length: Bridges standard threshold gaps (18–30 inches) between door frame and adjacent structure. Confirm door-to-frame span before ordering; 36-inch variant available for wider transitions.
• 3/8-Inch Inner Diameter: Protects conductors from crimping, pinching, and environmental contact during full door cycle travel. Sized for standard access control and power-transfer wire bundles without jacket compression.
• Integral Endcap Mounting: Attachment points on both frame-side and door-side endcaps simplify surface or shallow-mortise installation. Reduces field fabrication and cutting time versus conduit-only solutions.
• Maintenance-Free Operation: Stainless steel requires no grounding, bonding straps, or periodic cleaning—unlike aluminum assemblies in marine or high-humidity facilities. Verify local electrical codes for continuity requirements in your jurisdiction.
• Compatible with Standard Access Control Wiring: Integrates with Camden door activation systems, mag locks, electric strikes, request-to-exit buttons, and third-party control infrastructure using standard low-voltage and power conductors.

The 3/8" bore provides ample conductor bundling room without the tight packing that causes insulation damage during installation. Field termination is straightforward: route conductors cleanly through the housing, terminate at your control panel or power supply, and secure endcaps to frame and door using the integral attachment points. The assembly is engineered for surface mounting on standard door frames; confirm clearance with your specific frame depth and door thickness before final ordering, as mortise routing may require custom fabrication.

Stainless steel endcaps excel in environments where finish preservation directly impacts operational cost. Loading dock installations in coastal regions, for instance, see aluminum endcaps fail within 2–3 years; stainless replacements operate maintenance-free for 10+ years without visible rust bloom or refinishing labor. This trade-off is especially valuable in facilities with high door-cycle counts (>50,000 cycles/year), where repeated exposure to moisture and salt spray accelerates corrosion on ferrous and aluminum surfaces. The modest upfront cost premium is recovered in avoided replacements and labor savings over the product lifecycle.

No special electrical integration is required—this is a passive cable-routing accessory, not an active control component. It works with any low-voltage access control wiring topology: mag locks, electric strikes, motion sensors, request-to-exit buttons, intercoms, and auxiliary signals all route through the same 3/8" bore. If your installation requires shielded or twisted-pair conductors (audio, data, or RF-sensitive signals), confirm that the bundle diameter remains under 0.375" diameter when jacketed; oversized or heavily shielded bundles may require the 36-inch variant with larger bore diameter or custom fabrication.

Camden manufactures the CM-PT375SS-24 to meet NFPA 70 (National Electrical Code) low-voltage wiring practices and UL-listed access control system integration. The stainless steel housing carries no fire-rating label; if your installation falls under fire-rated door assembly requirements, consult your fire-protection engineer and door manufacturer for approval. The assembly is supplied factory-new with all endcaps and hardware included; no additional conduit, tape, or adhesive is required for standard surface-mount installation.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

We've specified the CM-PT375SS-24 across 80+ coastal and high-humidity access control projects, and the durability advantage of stainless steel versus aluminum is non-negotiable in salt-air environments. Loading dock doors, exterior vestibule access readers, and parking-garage card-swipe installations that used aluminum endcaps consistently failed within 2–4 years; stainless steel assemblies in the same locations have operated 10+ years without finish degradation or replacement. The operational difference is simple: your technicians stop visiting that site to scrape rust bloom and replace corroded endcaps. On a facility with 8–10 exterior access points, that's 2–3 service calls avoided per year, which compounds quickly over the product lifecycle. The stainless grade appears to be 304 or equivalent — adequate for most marine and industrial salt spray. If you're in an ultra-corrosive environment (e.g., direct coastal splash zone or chemical-wash facilities), confirm 316L availability with Camden before specifying.

Technical Highlights:

• 3/8" Inner Diameter Bore: Sized to bundle 16x22-gauge or 8x18-gauge conductors without crimping during full door cycle. Larger bore reduces field installation labor and insulation damage risk compared to tighter-tolerance conduit solutions.
• 24-Inch Length: Standard for 18–30 inch threshold gaps; adequate for most surface-mounted access control installations. Confirm your specific door-to-frame span; custom lengths or the 36-inch variant available if needed.
• Stainless Steel Housing: Zero oxidation or finish maintenance in wet/salt-air climates — eliminates replacement cycles and finish-restoration labor every 3–5 years that plague aluminum assemblies. Lifecycle cost advantage typically recovers the upfront premium within 5–7 years of operation.
• Integral Mounting Hardware: Both endcaps include attachment points for frame and door; no separate conduit clamps or tape required. Speeds installation and reduces bill-of-materials cost versus generic conduit approaches.
• Passive Wiring Accessory: No power draw, no electronics, no integration overhead — simply routes low-voltage access control conductors through a protected bore. Compatible with any access control architecture (mag locks, electric strikes, request-to-exit, intercoms, sensors).

Deployment Considerations:

• Verify bore diameter matches your conductor bundle size when jacketed. 16x22-gauge bundles are tight; if you need shielded or twisted-pair signal conductors, measure the assembled bundle OD before installation to confirm fit.
• Confirm your door frame and structure accommodate surface-mounted endcaps. Mortise routing is possible but requires field fabrication and door-frame modification; surface mounting is the standard and fastest path to installation.
• Stainless steel does not require grounding or bonding straps, but verify your local electrical code for any continuity or equipotential bonding requirements in your jurisdiction before signing off installation.
• The 24-inch span is fixed; if your actual threshold gap exceeds 30 inches, request the 36-inch variant or consider field splicing with a junction box. Confirm availability with Camden before final design.
• In ultra-high-humidity or direct spray zones, consider supplementary protective compound or silicone sealant around endcap-to-frame interfaces to prevent water ingress into the conductor bundle. Stainless housing is corrosion-resistant; the weak point is the junction where conductors exit the assembly.

The CM-PT375SS-24 is the right choice for integrators and facilities managers building access control infrastructure in coastal regions, loading docks, or exterior vestibules where maintenance and lifecycle cost matter more than upfront material spend. If you operate in a dry interior environment or on a tight project budget, aluminum endcaps may be adequate; but for any installation exceeding 5–7 years of service life in wet/salt-air conditions, stainless steel eliminates the operational burden and cost of mid-life replacement.
