Sargent 8237 LSF Trim Classroom 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 Classroom function (ANSI/BHMA F05) with LSF trim -- the F lever carried on the LS Security Escutcheon.
Classroom Function (ANSI/BHMA F05)
How the lock behaves at the opening, stated as the catalog states it, with what each line means in practice:
- Key Control: Key outside retracts latchbolt, also locks & unlocks outside trim — the key does two jobs at this opening -- it retracts the latch for entry, and it sets whether the outside lever is locked or free.
- 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.
- Multi-Function Lockbody: A multi-function 8200/7800 lockbody — one lockbody covers nine functions across the series, so a single case is stocked instead of nine.
LSF Trim Design
LSF pairs the LS Security Escutcheon (2-1/2" W x 7-3/4" H (64 x 197mm), forged security escutcheon; the cylinder is protected by the escutcheon and four spanner security screws are exposed on the inside trim) with the F lever (4-1/2" (114mm) long, +/- 1-15/16" (49mm) return). The carrier is an escutcheon -- a full plate covering the lock area, a different part from a rose and a different door preparation.
- Carrier: LS Security Escutcheon, 2-1/2" W x 7-3/4" H (64 x 197mm) (forged security escutcheon; the cylinder is protected by the escutcheon and four spanner security screws are exposed on the inside trim)
- Lever: F lever -- 4-1/2" (114mm) long, +/- 1-15/16" (49mm) return
- Handing: Handed trim; specify LH, RH, LHR or RHR 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
- Security trim: Cylinder is protected by the escutcheon; (4) spanner security screws are exposed on inside trim standard.
