Trimax UMAX50D Universal Trailer Coupler Lock | Dual-Purpose U-Lock, 9/16" Shackle

Trimax's UMAX50D is built to do double duty: lock it over your trailer coupler to stop hookups, or flip it into U-lock mode to secure other gear. The dual-ratchet mechanism grips tight against the coupler with no play, and the shackle covers a full 360 degrees so there's no exposed edge to pry or hammer on.

• Dual-ratchet locking system for a tight, tamper-resistant fit
• Converts between coupler lock and U-lock for added versatility
• 360-degree shackle coverage resists prying and hammering
• Weather-resistant keyhole cover keeps out dirt and corrosion
• Fits most coupler types from 1-7/8" to 2-5/16"

Backed by a limited lifetime warranty, in a chrome die-cast housing built for everyday towing security.
