Secure Trailer Locks for Drivers

If you only require TWO #40 padlocks, and not three, we will credit you $14.00 after the transaction has been paid. Please indicate the adjustment after the purchase. This lock combination comes with 10 keys and provides complete trailer security with a single key.

The COUPLER LOCK FEATURES protect unattended trailers and guard against tow-away theft. It fits 1-7/8", 2", and 2-5/16" couplers from various manufacturers, including Reese, Fulton, Valley, Atwood, Shelby, Putnam, Hammerblow, Dutton, Lainson, and UFP. The advanced locking mechanism resists picking and prying, and the lock is rekeyable. Installation and removal are straightforward, and the lock is designed to resist rust and corrosion. It is backed by a Limited Lifetime Warranty.

The PADLOCK FEATURES include a 2-3/4" (70mm) wide stainless steel body that resists corrosion. The case-hardened 3/8" steel shackle provides extra cut resistance, and the double deadbolt locking mechanism guards against pulling. The key retaining feature ensures the padlock is not left unlocked, and the fully shielded design minimizes shackle exposure.

The LATCH LOCK FEATURES are not recommended for all 2-5/16" couplers. The #37 latch lock will fit some 2-5/16" couplers, but not those with the latch partially recessed from the top surface or wider than 7/8". The latch lock works well on 1-7/8" and 2" couplers. The 7/8" (21mm) Armored Shackle Guard helps block bolt cutters, and the revolving, case-hardened steel shackle sleeve resists cutting and sawing. The shackle sleeve can be removed to secure the coupler latches. Thousands of key changes maximize key integrity, making the lock ideal for marine and other harsh environments.

This Total Trailer Security system is Keyed Alike, meaning one key opens all five locks. Each lock comes with two keys, for a total of ten keys. Multiple 5KA trailer lock packages can be keyed alike, so if you order a quantity of 2, 3, or more, they will all be keyed the same.

The round padlocks have a 2-3/4" (70mm) wide laminated stainless steel body that resists corrosion. The latch lock (model 37KABLK) does not fit some 2-5/16" couplers, so for those, the better lock set is the Master Lock - 5 Trailer Locks Keyed Alike 5KA-37940-3.

The coupler lock fits 1-7/8", 2", and 2-5/16" couplers, as described in the list of compatible manufacturers.
