S5 Coupler Lock for Demco 2" Drop-Cast A-Frame Trailer Couplers (LCS013)
Product Info
S5 Coupler Lock for Demco 2" Drop-Cast A-Frame Trailer Couplers
Protect your trailer against unauthorized hookups with the S5 LCS013 heavy-duty coupler lock. Built specifically for compatible Demco 2-inch drop-cast A-frame couplers, this security device helps block access to the trailer's ball connection when the trailer is parked or unattended.
Purpose-built fitment matters when protecting a trailer. Unlike a generic lock selected only by hitch ball diameter, this S5 model is intended for the distinctive shape of the Demco drop-cast A-frame coupler. It provides a substantial physical theft deterrent for compatible utility, cargo, and equipment trailer applications.

Confirm the Casting
Verify that the existing coupler is the Demco 2-inch drop-cast A-frame design. Similar-looking stamped, straight-tongue, or adjustable-channel couplers should not be assumed compatible.
|
|
Parking Security
Fit the lock to the uncoupled trailer as instructed by the manufacturer. Confirm that the assembly is secure before leaving the trailer unattended.
|
|
Additional Security
Consider combining coupler security with appropriate wheel locks, secure parking, lighting, and other physical security measures.
|
|
Before Towing
Remove the security lock completely and verify normal coupler operation, hitch engagement, and the trailer's regular pre-trip safety checks.

R&P Repair Insight | A-Frame Does Not Mean Universal
A-frame describes the trailer tongue configuration, but not the exact shape of every coupler installed on it. A cast Demco coupler may have a significantly different body and latch profile from a stamped steel A-frame coupler.
Before purchasing, compare the coupler's manufacturer markings and body shape with the S5 LCS013 application. Clear front, side, and top photographs can help determine whether the correct lock has been selected.
