Trailer Coupler Lock, Fits 1-7/8 to 2-5/16 in, 4 Keys

Trailer coupler lock protection helps deter theft by covering your straight tongue ball coupler and blocking access to the latch and chains. Built from reinforced carbon steel with a thick-wall design, this heavy-duty hitch lock fits common 1-7/8 in, 2 in, and 2-5/16 in coupler sizes for RV, trailer, and boat security. Powder coating and a dust cap support reliable outdoor use.

When your trailer is left in a driveway, storage lot, or campground, the coupler is an easy target. This nesting-style lock adds a physical barrier around the hitch connection to discourage tampering and slow down opportunistic theft attempts. Keep an extra key with your tow vehicle, and use the dust cap after locking to reduce exposure to rain and road spray. Grab yours today and lock up before your next trip.
