The vehicle is mounted onto the bench by using bench mountings and chassis clamps. The bench mountings are placed in the tracks of the base frame. The chassis clamps are bolted to the arms of the bench mountings and the clamps have serrated jaws which grip the sill flange of the vehicle. Includes B106 and B310. The B310 Bench Mounting for the Mark I-lV Mark 5 - Mark 6 and Compact bench systems features click-in mounting. The bench mounting is placed in the proper position directly with only two bolts remaining to be tightened making the B310 quick and easy to install and remove.
