Sargent 8237 FEF Trim Classroom Function Mortise Lockset

Chosen by specifiers who would rather over-build an opening than revisit it.

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 FEF trim -- the F lever carried on the FE Freewheeling 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.

FEF Trim Design

FEF pairs the FE Freewheeling Escutcheon (forged brass outside escutcheon, vandal-resistant trim; the outside lever swings freely down to 70 degrees in the locked position and returns automatically) 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: FE Freewheeling Escutcheon, forged brass outside escutcheon (vandal-resistant trim; the outside lever swings freely down to 70 degrees in the locked position and returns automatically)
• 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
• Freewheeling action: This design allows the outside lever handle to swing freely, down to 70 degrees, in the "locked" mode. This eliminates resetting the trim after vandalism attempts because the lever automatically returns to its original position
