AR-021EXZ

Following in the Lobster Tools tradition of production quality tools, Lobster introduces a new heavy duty hydra-pneumatic riveter. The model AR-021EXZ is specifically designed to set 3/16" and 1/4" two piece lockbolts and structural blind rivets. Lobster's exclusive Soft-Set shockless technology absorbs jarring vibrations, which enhances worker safety and minimizes the risk of CTD's.
