The Allstar door bar clamp easily fastens around a 1-1/2" door bar allowing a steel door bar plate to be mounted to the outside of the door bar area. This clamp eliminates the need to weld mounting tabs or the door plate directly to a finished chassis. Each clamp is sold individually and includes 1/2" hardware. Allstar also offers a wide variety of differently sized, 1/8" thick 1011 mild steel door plates to complete job right.
