Double Cylinder Deadbolt Operation

The Tuff Stuff BD5503A is a double cylinder deadbolt that requires a key on both the exterior and interior sides of the door. It is suited for entry doors where keyed access is preferred from either side, such as doors adjacent to glass panels. Builders grade certification indicates it meets standard residential hardware requirements.

Polished Brass US3 Finish

The lock features a polished brass US3 finish that provides a bright, traditional appearance for standard residential doors. As a mechanical deadbolt, it operates without electrical power and produces no operational noise. The mechanism relies solely on manual key rotation for locking and unlocking the bolt.

Adjustable Backset and Included Components

An adjustable backset accommodates door preparations ranging from 2-3/8 inches to 2-3/4 inches, allowing installation on common door configurations without modification. The package includes the deadbolt assembly, the adjustable backset mechanism, and two keys for immediate setup. Double cylinder design means a key is always needed for egress.

Questions about this item

How do I install the BD5503A deadbolt and which step is commonly missed?

Fit the adjustable backset to either 2-3/8" or 2-3/4" to match your door prep, then secure the double cylinder mechanism; the step often missed is setting the backset before mounting the lock body.

What maintenance or replacement will the BD5503A need over time?

Periodically lubricate the keyways and cylinders with graphite powder; replace the cylinder set if keys begin to bind or the brass finish shows heavy wear.

What is the first limitation you hit with the BD5503A under sustained use?

The builders-grade rating means internal components will wear faster than heavy-duty grades, so expect cylinder stiffness or key sticking after extended daily operation.
