Camden Aluminum endcaps 18\" length (Formerly - CM-PT250AL-18

We've installed hundreds of access control door activation systems across commercial and hospitality deployments, and cable termination integrity is one of those silent failure points that often gets overlooked until a power transfer line fails during an emergency lockdown event. The Camden CM-PT250AL-18 endcaps sit at that critical junction — they're not fancy, but they do exactly what they're designed to do: hold a 1/4" cable sheath in place and prevent conductor separation at the endpoint. In our experience, the aluminum material holds up well in typical indoor access control environments where moisture isn't a primary concern; we've seen minimal corrosion on 5+ year old installations in dry HVAC conditions. The real value proposition here is retrofit compatibility with legacy CM-PT14 infrastructure — if you're maintaining a door activation system that was spec'd a decade ago and an endcap has worn or cracked, you don't want to redesign the entire cable run. The 18-inch pre-cut length matches standard access control cable runs to a single-door strike or multi-zone panel, which means less field cutting and fewer opportunities for conductor exposure during installation. One caveat: we've seen installers grab endcaps without verifying the cable OD first, and mismatches cause intermittent electrical contact at the termination point. Slow short circuits that manifest as door lock chatter or erratic strike behavior. Always verify 1/4" ID match before assembly.

Technical Highlights:

• Aluminum Material: Corrosion-resistant construction suitable for indoor access control deployments. Lighter weight than steel, reducing strain on cable runs in vertical or overhead installations. Eliminates the cost premium of stainless steel in non-corrosive environments.
• 1/4" Inner Diameter Bore: Precision-machined to accept standard Camden power transfer cable conduit. Secure mechanical fit prevents cable migration or rotation under vibration or physical stress at the termination point.
• Multi-Conductor Accommodation: Designed to house 4-conductor 22-gauge or 2-conductor 18-gauge wire bundles without conductor separation or cross-connection. Maintains signal integrity for power and control circuits routed through the cable.
• Pre-Cut 18" Length: Eliminates field fabrication and reduces installation labor. Matches standard access control cable run distances to single-door strike and multi-zone panel installations without custom cutting.
• Hand-Assembly Process: No special tools, torque wrenches, or calibrated assembly equipment required. Standard integrator skill set and field toolkit sufficient for termination and installation.

Deployment Considerations:

• Verify cable inner diameter is precisely 1/4" before assembly — undersized or oversized cable will not seat properly and will create mechanical and electrical contact failures at the endpoint.
• Aluminum is adequate for indoor commercial and institutional deployments; do not use in outdoor, high-moisture, or chemical-exposure environments where corrosion will degrade endcap and conductor contact.
• 18-inch length is a standard pre-cut dimension for access control cable runs to single-door activation systems and close-proximity multi-zone panels. Verify cable run distance against this length specification before ordering to avoid field cuts or splicing.
• Installation is hand-assembly only — no calibrated torque or press-fit equipment available. Ensure endcap bore is clean and cable sheath is free of debris or nicks before seating to maintain contact pressure across the termination point.
• Retrofit applications benefit from direct CM-PT14 compatibility; however, verify the legacy endcap bore diameter and cable OD match before substituting — OD specifications may vary across cable manufacturers or cable gauge changes.

The CM-PT250AL-18 is a straightforward termination component aimed at integrators and maintenance teams managing established access control infrastructure or building new door activation systems where cost-effective, reliable cable endpoints are the priority. If you're standardizing on Camden power transfer cable and need endcap replacements or new installations, this endcap delivers dependable performance without design complexity or integration overhead.
