Cut- and saw-resistant: This concealed swivel lock is made of robust 45# solid steel and brass cylinders, both strong enough to prevent the lock from being cut or sawed open, greatly enhancing its security. These swivel locks are designed to resist damage, and their concealed swivels make cutting difficult. A key retention protection ensures the lock is never left unlocked.

Excellent security: The advantage lies in their 6-pin cylinders instead of 5-pin cylinders, offering slightly better pry resistance, and the use of steel instead of easily drilled aluminum. The swivel locks are chrome-plated for increased smoothness and abrasion resistance. Their robust construction ensures durability in outdoor conditions. This robust concealed swivel lock is ideal for those seeking robust security.

Swivel lock dimensions: To ensure the trailer door lock is installed correctly, measure the swivel/latch on the trailer door. Also check the depth of the hole in the swivel. The lock body diameter is 2-7/8 inches (73 mm). The lock cylinder is 9 1/16 inches (23 cm) long, and the internal ring diameter is 3/8 inch (10 mm). The lock cylinder will not engage if the center of the hole is more than 19/32 inches (15 mm) from the edge.

Convenient key-matching design: The two black heavy-duty locks in this set use the same key (key-matching), simplifying the management of multiple locks. Ideal for fleet managers or anyone tired of carrying heavy keychains.
