Schlage A53PD Plymouth (PLY) Grade 2 Entrance Cylindrical Lock

The Schlage A53PD Plymouth is a Grade 2 entrance cylindrical knob lock from the Schlage A Series, the lock line Schlage has manufactured since 1925 and the most widely installed cylindrical lock series in the United States. The Plymouth knob design fits light to medium commercial applications, multi-family residential buildings, military barracks, offices, and heavy-duty residential doors where ANSI Grade 2 certified security is the specification requirement.

Schlage A53PD Plymouth Knob, Grade 2 Entrance Lock, ANSI Function F109

The A53PD carries ANSI Function F109, the standard entrance or office function. The latchbolt operates by knob from either side at all times when the outside knob is not locked. Two separate push-button locking modes are available: pushing and turning the interior button locks the outside knob and holds it locked until a key is used to unlock it from the outside; pushing the button without turning locks the outside knob until it is manually unlocked by the interior knob rotation or a key from the exterior. The inside knob is always free for egress in both modes. This dual-mode button makes the A53PD the correct choice for office entries, residential front doors, and light commercial entrances where the occupant needs flexible control over when the door is accessible from outside.

The Plymouth knob style is a smooth round knob profile, the most widely used A Series knob design across residential and commercial projects.

Patented Door Range Adjuster

The Schlage A Series includes a patented door range adjuster that allows quick field adjustment for doors ranging from 1-3/8 inch to 1-7/8 inch thick. No tools required to change the door thickness setting. On renovation projects where doors vary in thickness across a building, this feature eliminates the ordering complexity of specifying separate extended-chassis versions for thicker doors within the standard range.

Cold-rolled steel hubs are machined and threaded to prevent chassis loosening over time. The heavy-duty cast mounting plate with specially tapped holes keeps the lockset tight against the door face under repeated use.

Keying and Cylinder Options

The A53PD Plymouth is available in multiple keying configurations: keyed different, keyed alike, master keyed, grand master keyed, and construction keyed. Construction keying allows the lock to be operated by a temporary construction key during the build phase, then converted to the permanent key system when the project completes. Interchangeable core cylinder options are available for facilities running IC key management programs.

Available finishes include 626 Satin Chrome, 605 Bright Brass, 612 Satin Bronze, 613 Oil Rubbed Bronze, and additional options. Confirm finish and keying requirements at order.
