Trim-Loc is the only tool on the market used to measure, mark and install casement trim. With this handy, lightweight tool in your belt, trimwork will go like clockwork. Trim-Loc's built-in tape measure hook slots and preset reveal allow you to accurately measure all of your trim pieces at once, saving you hours of time. After you measure and record the trim lengths, use Trim-Loc to accurately transfer the measurements to your trim stock and mark cut lines. Finally, use Trim-Loc to hold the trim pieces in perfect alignment while you nail them in place. Trim-Loc holds the trim fast, preventing the nail gun from throwing it out of alignment. Use the starter nail guide to help prevent costly splits and wasted material. For better convenience and efficiency, purchase two Trim-Locs: one for your tool belt and one for mounting to your bench — a must for carpentry crews and large trim jobs. Trim-Loc is a perfect companion for your miter saw because it's easy to hold & doesn't get in the way.
