Accentra D211 Single Cylinder Deadbolt, Grade 2, 2-3/8" Backset

The Accentra D211 is a Grade 2 single cylinder deadbolt with a 2-3/8-inch backset, certified to ANSI/BHMA A156.5 and carrying ANSI function E0152. The deadbolt operates by key from the exterior and thumbturn from the interior. The face plate measures 2-1/4 inches by 1 inch, and the package includes both metal door and wood door strikes with strike reinforcement as standard. It installs on doors prepared to ANSI/BHMA A156.115 specifications using a bored-hole installation on square or beveled doors, opening in or out. Non-handed and field reversible. SKU: D211.

What ANSI E0152 function means on the D211 single cylinder deadbolt

ANSI function number E0152 defines a single cylinder deadbolt: key from the outside retracts and extends the bolt, thumbturn from the inside retracts and extends the bolt. The interior thumbturn always operates freely without a key. This is the standard auxiliary deadbolt function found on virtually every commercial and institutional door that uses a deadbolt as a secondary security bolt in addition to the primary latchbolt from the cylindrical or mortise lockset.

The D211 is a deadbolt only. It has no latch, no lever handle, and no automatic door retention. It provides a dedicated key-controlled bolt that stays thrown until retracted by the exterior key or the interior thumbturn. This deadbolt is installed as a secondary security measure above or below the primary lockset on the door. For the Grade 1 version of a cylinder x thumbturn deadbolt in the Accentra D-series, the Accentra D112 cylinder x thumbturn deadbolt is also stocked.

What Grade 2 means for the D211 and which applications it suits

ANSI/BHMA A156.5 Grade 2 is the second tier of deadbolt performance, below Grade 1 and above Grade 3. Grade 2 covers a less demanding test sequence than Grade 1 in terms of bolt throw strength and cycle endurance, making it appropriate for light commercial applications, multifamily residential properties, and interior doors within a facility where the deadbolt sees moderate use and the security requirement is below the Grade 1 threshold. Grade 2 is not the correct specification for high-traffic commercial entry doors, institutional applications with heavy daily use, or any door where a Grade 1 rating is specified on the hardware schedule.

The D211 is correctly used on apartment unit entry doors, interior office doors in light commercial settings, storage room doors, and similar applications where a reliable keyed deadbolt is required without the Grade 1 performance level. For applications requiring Grade 1, the D-series Grade 1 deadbolts in the Accentra line are the appropriate specification.

What strikes are included with the D211 and what the D211 vs D212 backset difference means

The D211 includes both a metal door strike and a wood door strike, each measuring 2-3/4 inches by 1-1/8 inches, with strike reinforcement supplied as standard. This means the installation package is complete for both hollow metal and wood door applications without requiring a separate strike order. The included strike reinforcement reduces door frame vulnerability at the bolt pocket, which is the most common point of forced entry failure on deadbolt installations.

The D211 uses a 2-3/8-inch backset. The D212 is the same deadbolt in a 2-3/4-inch backset configuration. Both models are non-handed and field reversible, covering left-hand, right-hand, inswing, and outswing doors without modification. Confirm the backset dimension by measuring from the door edge to the center of the bore hole before ordering. For Accentra lever locks and other Accentra hardware, the Accentra lever locks catalog is available. For key cylinders and blanks compatible with the Accentra cylinder, the cylinders, cores, and keys section covers the options.

Confirm the backset dimension matches the door prep before ordering. Strikes included. Multiple finishes available. Non-handed and field reversible.
