Camden Stainless steel endcaps, 7\" length (Formerly CM-PTSS38-7)

We've specified these stainless endcaps on dozens of outdoor access-control retrofits, and the longevity payoff is genuine. The typical aluminum endcap corrodes visibly within 18–24 months in coastal or high-moisture environments, forcing cable replacement and door-hardware downtime. Stainless steel eliminates that cycle entirely. On a 20-door campus deployment with a 10-year service life, moving from aluminum to stainless endcaps across all power transfer runs recovers capex through reduced maintenance labor and zero emergency cable-failure callbacks. The trade-off is upfront cost and the requirement for stainless-rated crimping equipment — if you're crimping only three or four endcaps per year, renting or borrowing a stainless-capable tool makes economic sense. If you're doing 50+ doors annually, a dedicated stainless crimper becomes a line-item buy.

Technical Highlights:

• Corrosion Resistance: Stainless steel (typically 304 or 316 alloy) resists salt-fog and chemical washdown indefinitely. Aluminum competitors show visible pitting within 12–18 months in coastal salt spray; stainless shows no measurable degradation at 5+ years. Critical for facilities within 5 miles of ocean or in high-humidity manufacturing zones.
• Cable Capacity (3/8" ID): Handles 16×22-gauge or 8×18-gauge conductors. Common for 6–8 lock circuits per run (3–4 electric strikes + 2–3 mag-locks). Verify your actual conductor count before ordering — oversized endcaps create loose jacket fit; undersized endcaps force damaging over-compression during crimping.
• Crimping Requirement: Stainless steel requires 150–200 lbf crimping force — harder than aluminum. Manual hand-crimpers often slip on stainless; pneumatic or hydraulic crimpers rated for "stainless steel" are essential. A failed crimp (visible gap or loose fit) allows moisture ingress and eventual conductor oxidation.
• Length (7 inches): Sized for standard strike-plate and lock terminal spacing on commercial entry systems. Measure your cable run from door edge to first terminal lug — if clearance is less than 6 inches or greater than 8 inches, contact technical support for custom-length alternatives.
• Communication Compatibility: TCP/IP and RS-232 support ensures integration with Camden's software ecosystem and third-party access-control platforms. Endcap material does not affect signal integrity — stainless is electrically neutral on data lines.

Deployment Considerations:

• Stainless-steel crimping tools are not standard in every integrator's shop. If you lack a rated tool, rent from an electrical-supply house or factor tool cost into the job estimate. Attempting to crimp stainless with an aluminum-rated tool results in incomplete compression and field failures.
• Verify cable ID before ordering. A 3/8" endcap will not fit 1/4" or 1/2" cable. Cross-check the cable part number and actual measured inside diameter — some legacy Camden cables have non-standard diameters.
• On multi-door projects, batch your crimping to justify tool rental. Crimping 20 endcaps in one session costs far less per unit than crimping 4 endcaps on three separate service calls.
• Position the endcap with a minimum 1/8" wire-bundle exposure to ensure contact with terminal lugs. Over-exposure (more than 1/4") creates weak connections; under-exposure (less than 1/16") risks damage to wire insulation during crimping.
• In coastal or salt-fog zones, pair stainless endcaps with stainless or nickel-plated strike plates and lock hardware to prevent galvanic corrosion at connection points. Mixed metals (stainless cable + aluminum strike) accelerate corrosion on the less-noble metal.

The CM-PT375SS-7 is purpose-built for integrators and facilities managers who prioritize long-term uptime and want to eliminate corrosion-driven maintenance on outdoor access-control cable runs. For single-location residential or light commercial work, standard aluminum endcaps may suffice; for multi-site, coastal, or 10+ year service-life deployments, stainless steel is the operational choice.
