It speeds up the job tremendously and eliminates the potential for damage by hammering. Simply lay the brad or point in position on the backing and squeeze the handles to draw the jaws together and to drive the brad.
Jaw depth is 1-5/8" and adjusts to a maximum opening of 3-3/4" (minimum 1/2"). The jaw travel for driving is 1/2". A magnetic insert in the tip of the fixed jaw helps hold the brad in place, and a rubber pad on the movable jaw prevents marring of the frame. Not for use on hardwood.
