Accentra D141 Blank Plate x Thumbturn Deadbolt, 2 3/8" Backset

The Accentra D141 is a Grade 1 blank plate x thumbturn deadbolt with a 2-3/8-inch backset, certified to ANSI/BHMA A156.5 and carrying ANSI function number E01111. The exterior face has a blank plate with no key cylinder. The interior face has a thumbturn that operates the bolt. This configuration is used when exterior access is controlled by a separate device, such as an electronic access control reader, a keypad, or an electrified strike, and the deadbolt provides only the mechanical bolt throw on the interior. Non-handed, field reversible, bored-hole installation. SKU: D141.

What blank plate x thumbturn means and when this deadbolt configuration is specified

A blank plate x thumbturn deadbolt has no key cylinder on the exterior. The exterior face is a finished plate with no keyway, no cylinder plug, and no mechanism that can be operated from outside. The interior thumbturn operates the deadbolt bolt from inside. This configuration is the correct specification when the door has a separate access control system handling exterior entry, and the deadbolt's role is to provide a mechanical bolt that the interior occupant can engage or release with the thumbturn.

Common applications include doors with electronic card readers, PIN keypad locks, or biometric devices that handle exterior entry as their primary function. The blank plate deadbolt provides a secondary locking bolt that the interior occupant controls independently of the access control system. It also appears on doors where no exterior entry is ever intended, such as emergency exit stairwell doors where the bolt is thrown from inside and the door has no exterior hardware beyond a panic device. For the cylinder x thumbturn version in the same D-series deadbolt, the Accentra D112 cylinder x thumbturn deadbolt is also stocked. For the broader range of auxiliary deadbolts, the auxiliary deadbolts catalog covers the available configurations.

What ANSI function E01111 and Grade 1 certification mean for the D141

ANSI function number E01111 is the standardized function designation for a blank exterior x thumbturn interior deadbolt under ANSI/BHMA A156.5. This number identifies the exact functional behavior of the deadbolt in a way that every hardware specifier, architect, and contractor reading a hardware schedule can confirm matches the intended door function. When a door schedule lists E01111, the D141 is the corresponding product in the Accentra line.

ANSI/BHMA A156.5 Grade 1 is the highest performance tier for auxiliary deadbolts, covering bolt throw strength, cylinder pull resistance on the thumbturn mechanism, operational cycle endurance, and bolt projection consistency. The D141 passes all Grade 1 requirements. For Accentra lever locks and other door hardware that pairs with the D141 on a complete door opening, the Accentra lever locks catalog is available. For cylinders, cores, and key blanks used on other doors in a project alongside the D141, the cylinders, cores, and keys section covers the available options.

Installation requirements and backset for the D141

The D141 uses a 2-3/8-inch backset, the shorter of the two standard deadbolt backset dimensions. This backset is required on narrow stile doors, some aluminum frame doors, and any door prep where the 2-3/4-inch backset does not fit the existing boring. A 2-3/4-inch backset version is available in the D series for standard commercial door preps. Confirm the backset dimension on the door before ordering to ensure the correct model is selected.

The D141 installs on doors from 1-3/8 inches to 1-3/4 inches thick using a standard bored-hole installation on square or beveled doors, opening in or out. The lock is non-handed and field reversible.

Confirm the backset dimension matches the door prep before ordering. Multiple finishes are available. The D141 is non-handed and field reversible.
