Dorma D860 Cylinder x Turn:
Dead bolt operated by key outside or by turn inside. Bolt automatically deadlocks when fully thrown. Providing increased security, reliability, and durability. DORMA offers a choice of rugged dead bolts to provide an added level of protection. The D800 Series are Grade 1 dead bolts available in both 2-3/8" and 2-3/4" (standard) backsets. The large dead bolt is made from stainless steel for strength and corrosion resistance. A HeavyDuty brass cylinder in a hardened steel housing surrounded by a heavy steel spin ring complete 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" screws for wood jamb installations. All of these features provide an exceptionally strong and secure dead bolt. All steel parts are zinc dichromate plated.

B category finishes, “do not match from one alloy or form of material to the next and from one manufacturer to the next.” The 613 finish may vary between manufacturers’ products and models.
In some instances, for customer convenience, the most appropriate BHMA finish symbols are used to indicate similarity of appearance, regardless of base metal or finishing process. Finishes of latches, strikes, cylinders/cores, and visible mounting screws, though similar in appearance, may differ from the finish of the trim. Finish designations in the 600 numbers are the BHMA (Builders Hardware Manufacturers Association) industry standard.
