The large dead bolt is made from stainless steel for strength and corrosion resistance. The design incorporates a heavy duty brass cylinder in a hardened steel housing surrounded by a heavy steel spin ring, reinforcing the security package in the door. This is coupled with a solid steel strike for use in a hollow metal frame and an
additional reinforcing plate with 3-inch screws for wood jamb installations.

The Grade 1 dead bolt is available in either 2 3/8-inch or 2 3/4-inch backsets. It is offered in a variety of configurations to satisfy virtually any situation encountered in the field. It is also available in the new DORMA SKC management system, as well as many standard keyways, in either standard or small format interchangeable core  cylinders.

Hardware is certified under the BHMA Product Certification program to meet all ANSI A156.5 - 2001 requirements. It is UL Listed for use as auxiliary hardware of 4-foot by 8-foot doors with a three-hour fire label. This durable lock is back by a 10-year mechanical warranty.
