Trimax Swing-Away Trailer Lock 5/8 x 6-1/8 in — Compact Coupler Lock, Quick Install

Whether stored in a driveway, parked at a job site, or left at a storage lot, trailers need a simple, rugged locking solution that fits common ball couplers. The Trimax TH6 is built in a compact footprint with a swing-away design so the lock clears the latch when the trailer is hitched and quickly swings into place when parked. Its measured 5/8" pin diameter and 6-1/8" body length suit a variety of small- and medium-sized trailer couplers while remaining easy to carry and install.

How does the Trimax TH6 attach to my trailer coupler?

The TH6 uses a pinned shank that inserts through the coupler latch area, then swings into position to prevent the coupler from closing on the hitch ball. Installation takes only a few seconds and requires no special tools. The swing-away function keeps the lock out of the way when the trailer is hitched and secures the coupler when parked.

• Pin diameter: 5/8" for sturdy anchoring
• Overall length: 6-1/8" for compatibility with many couplers
• Swing-away action clears the hitch while in use
