Trailer Lock - Theft Deterrent System
Whether pulling a trailer load of 4-wheelers, 4-hoofers, or driving a full-on semi tractor/trailer rig, the Spence Trailer Lock offers peace of mind by deterring theft. Additionally, the Spence Trailer Lock provides added safety and security for trailers parked on an incline or needing repair.
The Spence Trailer Lock is a Patented trailer theft deterrent system. The patent was granted on October 23, 2007; #7,284,641 B1. The idea was to design a trailer locking system that was easy to adjust, install, and use. The Spence Trailer Lock is currently available in two models: For the recreational market, we offer the STL-1SA, while for the commercial, three-axle tractor market, we have the STL-2C.
All locks are made of 6061-T6 polished aluminum, and the STL-1SA model weighs less than 18 pounds, while the STL-2C weighs less than 25 pounds. Each lock assembly comes complete with all the needed hardware except the padlock. For that, we recommend using the Master Lock #37D, M187XKAD, or 605 DAT.
Additional features include warning strips on either side. The warning strips call attention to the lock, saying to a potential thief that the trailer is protected against theft.
