Accentra D111 Cylinder x Thumbturn Deadbolt, 2 3/8" Backset

The Accentra D111 is a Grade 1 deadbolt with a key cylinder on the outside and a thumbturn on the inside, designed for commercial door applications where ANSI/BHMA A156.115 compliance, bored-hole installation, and reliable single-cylinder deadbolt operation are required. The deadbolt has a 1-inch (25mm) throw with a solid steel bolt body and a hardened, free-spinning steel pin insert. The backset is 2-3/8 inches (60mm). Metal and wood door strikes with strike reinforcement are included. The deadbolt is non-handed and field reversible. SKU: D111.

How the D111 single-cylinder deadbolt operates and where it belongs

The D111 uses a key cylinder on the exterior side and a thumbturn on the interior side. Entry from outside requires a key. Exit from inside is always available through the thumbturn without a key, which satisfies egress code requirements on most commercial and residential door applications. The single-cylinder configuration is the standard deadbolt type for office entry doors, suite doors, apartment entry doors, and any commercial door where keyless egress from inside is required.

The 1-inch solid steel bolt throw provides ANSI Grade 1 security depth when the bolt is fully extended into the strike. The hardened free-spinning steel pin insert in the bolt face resists sawing attacks by spinning when a saw blade contacts it, preventing the blade from cutting through the bolt. The Grade 1 rating is the highest classification under ANSI/BHMA standards for deadbolts and confirms the D111 meets the mechanical performance thresholds required for commercial installation.

What the 2-3/8 inch backset means and how to confirm compatibility before ordering

The backset is the distance from the edge of the door to the center of the bore hole where the deadbolt installs. The D111 is the 2-3/8-inch backset version of the Accentra D Series deadbolt. This is the standard backset for most residential and light commercial doors. The 2-3/8-inch backset is compatible with doors prepared to ANSI/BHMA A156.115 using a standard bored-hole installation, which requires a 2-1/8-inch diameter cross-bore and a 1-inch edge bore.

If the door has a 2-3/4-inch backset, the correct model is the D112, not the D111. Measure the existing backset on the door before ordering. The D111 is not field-adjustable between the two backset configurations. The 2-1/4-inch x 1-inch front plate and the 1-1/8-inch latch front filler are included standard with the D111. For replacement cylinders and keyway options compatible with the D111, the cylinders, cores, and keys section covers available options.

Door thickness range, handing, and included hardware for the D111

The D111 is standard for doors between 1-3/8 inches (35mm) and 1-3/4 inches (44mm) thick, covering the standard range for commercial hollow metal and wood doors. The deadbolt is non-handed, meaning the same unit installs on doors that swing in or out and on doors with left-hand or right-hand hinge placement, without any parts changes. Handing is field reversible if the application changes.

Both metal door strikes and wood door strikes are included, along with strike reinforcement hardware, so the installation is complete without sourcing additional strike hardware. The one-year mechanical warranty applies to the D Series deadbolt line. For the complete range of cylindrical deadbolts across all brands and configurations, the cylindrical deadbolts catalog covers all stocked options.

Confirm the backset is 2-3/8 inches and the door thickness is within the 1-3/8 to 1-3/4-inch range before ordering.
