Sargent 8297 LNB Trim Mortise Double Dummy w/Active Trim

Built for openings that are expected to outlast several tenancies.

The Sargent 8200 Series is a heavy-duty mortise platform for commercial and institutional openings. Certified to and exceeds ANSI/BHMA A156.13, Series 1000, Operational Grade 1 and Security Grade 1 with all standard trims. This listing is the Double Dummy w/Active Trim function with LNB trim -- the B lever carried on the LN Rose.

Double Dummy w/Active Trim Function

How the lock behaves at the opening, stated as the catalog states it, with what each line means in practice:

• Both Levers Turn: Trim on both sides are active — the levers on this dummy rotate, where the other dummy trims are rigid; turning one retracts nothing, because this function has no latchbolt and no deadbolt.
• Ships With the Lock Case: Includes lock case and armor front — this dummy includes the mortise case and its armored front, so it sets into a mortised pocket and shows a lock front on the door edge; the trim-only dummies do not.
• Not for the Inactive Leaf of a Pair: Not recommended on double door applications (will not accept latchbolt from active door) — this version will not receive a latchbolt from the active leaf, so Sargent does not recommend it on a pair of doors; the dummy trims prepped to take that latch are the trim-only 8293 (one face) and 8294 (both faces), which ship without a lock case and whose levers are rigid.

LNB Trim Design

LNB pairs the LN Rose (2" (51mm), round; the smallest of the standard roses) with the B lever (5" (127mm) long, +/- 1-5/8" (41mm) return). The carrier is a rose -- a compact plate around the lever, a different part from an escutcheon.

• Carrier: LN Rose, 2" (51mm) (round; the smallest of the standard roses)
• Lever: B lever -- 5" (127mm) long, +/- 1-5/8" (41mm) return
• Handing: Non-handed; no handing designation is required when ordering.
• Accessibility: All levers meet ADA compliance for national codes. Solid forged or cast. All lever height (+/- 1/16") measurements represent total distance from door face.
