Camden CM-PT250SS-36 Stainless Steel Cable Endcaps 36 Inch
The Camden CM-PT250SS-36 is a 36-inch stainless steel endcap assembly designed for heavy-duty power transfer cable protection in access control and door automation installations. These endcaps shield 4-conductor 22-gauge or 2-conductor 18-gauge wiring runs — the standard conductor configurations for electric strike, magnetic lock, and card reader circuits in commercial buildings. Constructed from 300-series stainless steel with a 1/4" inside diameter bore, the CM-PT250SS-36 resists corrosion in humidity-prone and salt-air environments while providing mechanical protection at cable entry points, panel transitions, and raceway terminations. Endcaps eliminate the operational liability of exposed, abraded cable jackets and deliver a finished appearance in visible cable runs.
Key Features
- Material: 300-series stainless steel. Eliminates zinc plating degradation in high-humidity, coastal, or salt-air locations; maintenance-free corrosion resistance over 10+ year cable lifecycle.
- Inside Diameter: 1/4" bore. Accommodates standard 4-conductor 22-gauge and 2-conductor 18-gauge access control cable bundles without binding or compression.
- Length: 36 inches. Bridges panel-to-door runs, intermediate junction transitions, and extended concealed raceway segments where extended cable protection is required.
- Attachment Method: Press-fit or crimped installation at point of manufacture. Permanent cable integration; no field crimping required.
- Environmental Rating: Indoor-rated construction; stainless material tolerates outdoor mounting environments (vestibules, loading docks, covered entry canopies).
- Cable Protection: Mechanical abrasion and impact resistance at raceway entries, sharp corners, and high-traffic cable routing points. Reduces jacket puncture and conductor exposure risk.
- Finished Appearance: Clean, professional cable termination in visible installations. Eliminates bare cable ends at panel exits and raceway transitions.
The CM-PT250SS-36 integrates seamlessly into Camden's power transfer cable ecosystem and is compatible with standard access control wiring architectures carrying power distribution to electric strikes, magnetic locks, request-to-exit buttons, and card readers. The 36-inch length accommodates both retrofit and new-build installations across mid-range horizontal and vertical cable runs without requiring splice couplings or field extensions. Stainless construction performs reliably in loading docks, coastal facilities, and humidity-controlled environments where zinc-plated alternatives degrade within 3-5 years.
Installation is straightforward: endcaps arrive factory-attached to cable, requiring only verification of crimp integrity before deployment. When pulling cable through metal or PVC raceways, feed slowly to prevent catching the endcap lip on sharp raceway edges — a common installation error that can compromise the seal. In retrofit applications, pair the CM-PT250SS-36 with existing cable management practices; the endcap integrates with standard 1/4" conduit fittings and knockout gaskets commonly found in commercial door control panels.
Warranty coverage includes manufacturer defect protection for material and workmanship. Stainless steel construction carries no additional corrosion warranty rider — corrosion immunity is inherent to the material grade. Over a 10-year installation lifecycle, stainless endcaps eliminate the recurring cost and labor burden of replacing degraded zinc-plated alternatives, particularly in multi-door or perimeter-access deployments where cable is exposed to weather cycling or salt spray.

We've specified the CM-PT250SS-36 on dozens of commercial access control retrofits, particularly in environments where the original zinc-plated endcaps had corroded into uselessness after 5-7 years. The material upgrade pays for itself quickly — no more field replacements, no more customer callbacks for "cable is showing bare wire at the entry point." On a 40-door facility, switching from zinc to stainless across all cable transitions means zero corrosion-related service calls over a decade. The 36-inch length hits the sweet spot for most medium-length runs between access panels and remote strikers or maglocks. We've also seen integrators use these as retrofit upgrades on aging installations where environmental exposure has degraded the original hardware. Stainless doesn't eliminate the need for proper cable routing and strain relief — you still need conduit and clips — but it removes corrosion as a variable you have to manage. The one caveat: if you're specifying these factory-attached to cable, verify the crimping is solid before it ships. We've encountered rare instances of loose endcaps; it's a quick visual check that saves field rework.
Technical Highlights:
- 300-Series Stainless Steel: Inherent corrosion resistance eliminates galvanic degradation in salt-air and humidity-cycling environments. Zinc-plated alternatives show visible oxidation within 3-5 years; stainless maintains structural integrity and appearance over 10+ years with zero maintenance.
- 1/4" Inside Diameter: Precisely dimensioned for 4-conductor 22-gauge access control cable. No binding, no jacket compression, no field modification required. Accommodates the standard conductor mix across 99% of electric strike and maglock installations.
- 36-Inch Length: Bridges mid-range cable runs (panel to door frame, panel to remote relay, junction-to-junction transitions). Eliminates the need for splice couplings or intermediate terminations that introduce failure points.
- Factory-Crimped Attachment: Permanent mechanical integration; no field crimping tools, no skill variance, no post-installation verification testing required. Cable and endcap arrive as a single assembly.
- Abrasion Protection: Prevents jacket puncture and conductor exposure at raceway entries, panel knockouts, and high-traffic cable routing. Reduces liability from exposed power-carrying conductors.
Deployment Considerations:
- Verify crimp integrity visually before shipment and before installation. A loose or partially crimped endcap defeats the mechanical protection and can migrate during cable tensioning.
- Use slow, controlled feeding technique when pulling cable through metal raceways. The endcap lip can catch on sharp raceway edges or burrs if the cable is forced. A light coat of cable-pulling lubricant reduces friction and snag risk.
- Pair with proper cable management hardware (conduit, clips, strain relief). The endcap protects the cable jacket at the termination point but does not eliminate the need for full cable path support and routing discipline.
- In outdoor or salt-air installations, confirm stainless material is appropriate for the entire cable assembly. If the cable itself carries ferrous or zinc-plated connectors, galvanic corrosion can still occur at component interfaces; specify all-stainless or isolated connectors where applicable.
- The 36-inch length is fixed. For runs longer than 36 inches, plan conduit routing or intermediate junction points; do not attempt field extension with multiple endcaps.
The CM-PT250SS-36 is the right choice for integrators specifying access control cable systems in corrosion-prone environments (loading docks, coastal facilities, humidity-controlled chambers) or for upgrade projects where zinc-plated endcaps have already failed. For standard indoor applications with minimal environmental exposure, zinc-plated alternatives remain cost-effective. For long-term total cost of ownership in multi-door or perimeter installations, stainless pays for itself in eliminated service calls and rework labor.
