GREX P650L 23 GA 2" Length Headless Pinner w/ Auto Lock-Out - P650L Introducing the P650L with Auto Lock-Out and 2" fastener capability. Adding the "L" (Auto Lock-Out) to the GREX P650L means: Less rework, less down time, and less tool and project damage. Now drive longer fasteners and prevent dry-firing with the same great quality and features expected from GREX. We added the Auto Lock-Out for those difficult, more critical jobs such as overhead crown molding. Dry-firing can cause damage to the tool and might cause damage to an expensive project. To prevent dry-firing, the Auto Lock-Out locks the GREX P650L with approximately 6-8 pins remaining in the magazine. The Auto Lock-Out over-ride button overrides the lockout allowing use of the remaining pins to tack a project-piece in place freeing the operator to reload. The high tolerance precision machined hardened steel driver, Posit-Lock nose cover and nose guide assembly aligns and seats the headless pin for optimal drive performance. What is Posit-Lock - it's tight tolerance, durability and functionality that reduces jams to a minimum. The P6 Series comes in five different designs: P630, P635, P650, P650L and the P650LXE. GREX, demanded by Pros, for more than 20 years has helped professionals rise to the top of their trade. Now explore.
