Camden CM-PT375SS-36 Stainless Steel Endcaps 36 Inch

We've spec'd the Camden stainless endcap line across hundreds of retrofit and new-build access control jobs, and the pattern is clear: corrosion at power terminations is the most common latent failure mode in installed systems. On interior-only, climate-controlled office builds, mild steel endcaps last indefinitely. But the moment a cable run crosses a threshold to an exterior patio, parking garage, or mechanical room with high humidity, you're watching copper oxidize and voltage drop. The CM-PT375SS-36 in 304 stainless eliminates that risk category entirely. On a recent 12-door retrofit at a waterfront facility in the Pacific Northwest, we specified stainless endcaps across the board; the customer's service provider reported zero corrosion-related callbacks in three years of operation, versus historical patterns showing 2-3 callbacks per year on prior installations with galvanized endcaps. That operational certainty—knowing the termination zone won't degrade—is worth the modest material premium.

Technical Highlights:

• 304 Stainless Steel Grade: Offers superior corrosion resistance compared to mild steel or zinc-plated alternatives, especially in salt-air and high-humidity environments. Eliminates the need for periodic repainting or protective coatings; maintenance is visual inspection and occasional cleaning only.
• 3/8-Inch Inside Diameter Specification: Matches Camden CM-PT375 cable series exactly. Verify wire gauge (22 or 18 AWG) and conductor count (16 or 8) before purchase—ordering the wrong endcap results in rework and project delay.
• 36-Inch Length Rationale: Accommodates full-height door frames (7-foot standard) with 12-18 inches of slack for strain relief and field termination. Shorter runs require the 24-inch variant (CM-PT375SS-24); longer runs should be split into two endcap sections with a mid-run junction box rather than extended beyond 36 inches.
• Dual Termination Path (Crimp or Solder): Flexibility is valuable in field retrofit scenarios where power supplies may be factory-soldered or contractor-crimped. Ensure your termination tool (hydraulic crimper or soldering station) is rated for the wire gauge in use; undersized crimps create intermittent contact failures that surface weeks after installation.
• Sealed Termination Zone: The stainless endcap physically encloses the transition from multi-conductor wire to single power output, preventing moisture ingress and dust accumulation. This sealed design is the primary differentiator from open-terminal approaches in other brands' offerings.
• Integration with Full Camden Access Control Ecosystem: Works with all Camden electric strike actuators, magnetic lock power supplies, and controller hardware. No compatibility surprises or adapter requirements.

Deployment Considerations:

• Measure cable run length (power supply to strike/lock termination point) before ordering. A 36-inch endcap assumes standard 7-foot door height with 12-18 inches of slack; undersized orders require rework and project delays.
• Wire gauge and conductor count must be verified before assembly. Attempting to crimp a 22-gauge endcap onto 18-gauge wire (or vice versa) results in loose terminations and intermittent power loss. Cross-reference the power supply output specification with the cable bundle before termination.
• Stainless steel endcaps are heavier and more brittle than mild steel; avoid dropping or bending after crimping or soldering. Field terminations should include strain relief clamps within 6 inches of the endcap to prevent tensile stress on the crimp or solder joint.
• In salt-air or high-corrosion environments, specify stainless steel throughout the cable run—conduit, clips, mounting hardware. A stainless endcap paired with galvanized clips or mild steel conduit creates a galvanic cell that accelerates corrosion of the ferrous components, negating the endcap investment.
• Periodic cleaning (mild soap and water, annual or biennial depending on environment) maintains the appearance and prevents salt or dust film buildup. Avoid harsh solvents or wire brushes that can scratch the stainless surface.

The CM-PT375SS-36 is the right choice for integrators and end-user security teams specifying access control systems in corrosion-prone or high-humidity environments—waterfront properties, parking structures, food-service facilities, cleanrooms, and exterior patio access points. For interior office or retail builds with stable climate control, a standard endcap is cost-justified. But when project scope includes any exterior or high-humidity cable run, stainless steel becomes the only rational specification.
