S5 Heavy-Duty Coupler Lock for Demco 2-5/16" Adjustable Trailer Couplers

PART # LCS002-DEMCO

Protect your equipment or dump trailer with the S5 LCS002-DEMCO adjustable coupler lock. Specifically engineered for Demco 2-5/16" adjustable couplers mounted in a C-channel, this heavy-duty steel security assembly helps prevent unauthorized coupling while shielding the coupler's mounting bolts from tampering.

Unlike a simple ball-socket lock, the S5 design addresses two vulnerable areas of the trailer connection: the coupler itself and the mounting hardware. Its formed steel housing, protective powder-coated finish, and included Trimax puck lock provide a substantial physical deterrent to trailer theft.

R&P Security Insight
A trailer coupler lock should protect more than the hitch ball opening. On adjustable-channel couplers, exposed mounting bolts can present another point of attack. The LCS002-DEMCO is designed to help shield that hardware while securing the coupler.

Key Features

Custom Demco Fit
Designed for compatible Demco 2-5/16" adjustable couplers installed in C-channel mounts.
Mounting Bolt Protection
Protective steel housing helps restrict access to the coupler's channel-mount hardware.
Heavy-Duty Construction
Fabricated structural steel with a protective powder-coated finish for demanding outdoor use.
Trimax Puck Lock Included
Includes a removable keyed puck-style lock to secure the assembly in place.

Compatibility
Intended for compatible Demco adjustable 2-5/16" couplers with C-channel mounting hardware. Not a universal lock for every 2-5/16" trailer coupler.
Theft Deterrence
The steel enclosure helps discourage unauthorized coupling and tampering with accessible channel bolts. No mechanical lock can guarantee complete theft prevention.
Installation
Use the lock only on the compatible coupler configuration. Follow the manufacturer's positioning and locking instructions, and check that the puck lock is fully engaged before leaving the trailer unattended.
Maintenance
Inspect the housing and locking mechanism periodically. Remove accumulated debris and maintain the lock mechanism according to the manufacturer's recommendations.

R&P Service Insight | Identify Your Coupler

Demco is the compatible coupler brand; S5 is the lock manufacturer. The two names refer to different components.

Before ordering, verify your Demco coupler's model, 2-5/16" ball size, adjustable mounting-channel design, and surrounding clearance. Photographs showing the coupler from the side and front, along with its mounting bolts, can help identify the correct lock.

Important: This product is a security lock, not a replacement trailer coupler, brake actuator, or towing attachment. It must be removed before towing. Check your exact Demco mounting arrangement against the S5 lock manufacturer's compatibility guidance.
