US Patent 10434993 Trailer leg securing devices and system

Devices and systems for securing and locking tractor trailer support legs in the down position are described herein. A securing pin passing through one of the support legs of a trailer while in the down position prevents the trailer legs from being raised. The pin can be locked in place such that only authorized users may remove the pin, raise the support legs, and move the trailer. A variety of kits for retrofitting existing trailers with securing devices are also provided.
