Our Maximum Strength Steel Lock Assembly is specifically designed for recessed 1 inch roller doors. Crafted from heavy-duty cast grade 30 steel, this lock assembly ensures optimum strength and durability. The pins are mechanically fastened in place, providing added security. With an extra thick padlock provision and a stainless steel spring, this lock assembly offers great security and eliminates door bounce. The zinc-plated steel construction is tamper-proof, and the trapped handle cannot be pulled out to bypass the keeper. It can also be used as a lift handle in the open position, making it practical and versatile for various door applications. Sold individually.
