Description
The Mul-T-Lock Hercular HD1 pairs the company's hardened, anti-wrenching bolt with a patented telescoping pin cylinder outside and a thumbturn inside: serious physical security with normal one-hand exit. It is the single-cylinder choice for storefronts, offices, and homes that want Mul-T-Lock protection without double-cylinder egress concerns.
The free-spinning hardened bolt defeats saws and pry bars, reinforced collars shield the cylinder from drilling and pulling, and the patented keyway means no unauthorized key copies, ever. We key Hercular deadbolts alike with other Mul-T-Lock hardware or into master systems daily; tell us your keying when you order.
