Telescopic stabilizing bars that bolt to existing leveling or stabilizing jacks to eliminate residual trailer movement. Swivel mount adapts to various jack angles. Travels with the jack during use and storage. 3/4" crank handle operation. Set of 2 with hardware.
The BAL 23216 Lock Arm is a telescopic stabilizing bar that mounts to an existing crank-down leveling or stabilizing jack to eliminate the residual trailer movement the jack alone can't fully remove. Where a standard scissor jack or C-Jack braces vertically against the frame, the Lock Arm extends horizontally from the jack to the ground at an angle — creating a triangulated brace that resists lateral and fore-aft movement much more effectively than a vertical jack alone.
Installation is a one-time bolt-on application. The unique swivel mount accommodates various jack angles without adjustment, and the telescopic Lock Arm body travels up and down with the jack during deployment and retraction — so there's nothing extra to manage during setup or storage. Locking and unlocking is done with a standard 3/4" crank handle. The kit includes two Lock Arms and complete mounting hardware for both.

Standard vertical jacks brace up and down effectively but provide limited resistance to side-to-side or fore-aft trailer movement. The Lock Arm addresses this by extending at an angle from the jack to the ground, creating a triangulated brace: 1. Jack is deployed vertically as normal 2. The Lock Arm — already mounted to the jack — automatically extends as the jack lowers 3. Use the 3/4" crank handle to lock the telescopic arm in position against the ground 4. The resulting triangle between the jack, Lock Arm, and ground dramatically reduces lateral and fore-aft movement To retract, simply unlock with the crank handle and raise the jack — the Lock Arm collapses back with it.
