The Truss Puck … need we say more? This guy is the workhorse of your facility! Loosen, slide and tighten. 100 different trusses to make? No problem! The Truss Puck is the man for the job. All parts are American steel machined right here in the United States. Designed at 1-1/4” tall, these Pucks will not interfere with your nit or finish roller.
