Sargent 8257 LP Trim Institutional Privacy Function Mortise Lockset

For doors opened thousands of times a year that still have to feel solid.

The Sargent 8200 Series is an extra-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 Institutional Privacy function with LP trim -- the P lever carried on the L Rose.

Institutional Privacy Function

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

• Staff Override of an Occupant-Set Privacy Turn: Key outside retracts latchbolt, overriding thumbturn when held in locked position — the occupant can set privacy from inside, and the outside key still overrides it -- which is what separates institutional privacy from a plain privacy set: the room can be made private without becoming a room staff cannot enter.
• Inside Thumbturn -- No Inside Cylinder: Thumbturn inside locks & unlocks outside trim — the outside lever is locked and unlocked by hand from the inside, with no key and no cylinder on that side; it does not retract the latch.
• Two Ways the Outside Trim Releases: Trim outside unlocks when the door closes or operating trim inside — either action returns the outside trim to unlocked -- closing the door, or working the inside trim.
• Life-Safety Free Egress: Trim inside always retracts latchbolt — the inside lever is never locked, so a single motion always gets a person out.
• Anti-Shim Protection: Auxiliary deadlatch — a small plunger beside the latchbolt rides the strike when the door closes; with it depressed the latchbolt cannot be shimmed back with a card.
• The Key Sets the Outside Trim Too: Note: Key locks & unlocks trim outside — the outside trim can be locked as well as released with the key alone, so control of that side does not depend on the occupant.

Two other Institutional Privacy functions differ by one behaviour each: on the 8258 the outside trim does not release when the door closes, and on the 8267 the key can only unlock the outside trim, never lock it.

LP Trim Design

LP pairs the L Rose (3-1/2" (89mm), round; the largest of the standard roses) with the P lever (5-1/2" (140mm) long, +/- 5/16" (8mm) return). The carrier is a rose -- a compact plate around the lever, a different part from an escutcheon.

• Carrier: L Rose, 3-1/2" (89mm) (round; the largest of the standard roses)
• Lever: P lever -- 5-1/2" (140mm) long, +/- 5/16" (8mm) return
• Handing: Non-handed; no handing designation is required when ordering.
• Accessibility: All levers meet ADA compliance for national codes. Solid forged or cast. Lever designs J, L and P have lever returns within 1/2" (13mm) or less of door face and meet California State Reference Fire Code. All lever height (+/- 1/16") measurements represent total distance from door face.
• Operation: Easy operation. Only 30 degrees of lever rotation required to retract latchbolt
