Sargent LC-NB-8713-F-ETB-84 Surface Vertical Rod Exit Device, Classroom Function, For 33-36 Inch Width, 84 Inch Height Door, Less Cylinder, Hex Key Dogging, Less Bottom Rod
The Sargent LC-NB-8713-F-ETB-84 is a heavy-duty surface vertical rod exit device engineered for demanding commercial openings. Configured for classroom function with the ETB exterior trim, it provides secure, controlled access from the outside while always allowing free egress through the push rail. This model is built for 33 to 36 inch wide doors up to 84 inches tall and ships less cylinder, giving you the flexibility to pair it with your facility's existing keying system. The less bottom rod (LBR) design eliminates the lower rod and latch for a cleaner look, easier maintenance, and improved floor clearance, while hex key dogging holds the latch retracted for push-pull operation during high-traffic periods.
Features
- Surface-mounted vertical rod exit device suited for wood and metal doors.
- Classroom (F) function lets authorized users control outside access with a key while egress stays unrestricted.
- Less bottom rod construction removes the bottom latch and rod for reduced maintenance and fewer tripping hazards.
- Less cylinder (LC) prep allows integration with your preferred keying system.
- Hex key dogging mechanically retracts the latch for convenient push-pull use.
- Sized for 33–36 inch wide openings on doors up to 84 inches tall.
- ETB (B) style escutcheon lever trim provides a durable exterior operating interface.
Functional Details
In classroom function, the outside lever is controlled by a key cylinder. A key unlocks the lever for passage, and the device can be locked or unlocked from the outside, while the inside push rail always permits free, immediate egress for life safety.
Arm Type Details
As a surface vertical rod device, the top latch engages a strike mounted at the door head. The less bottom rod design relies on the top latching point only, which keeps the floor area clear and simplifies installation and servicing without sacrificing secure latching at the top of the door.
Included Components
Device chassis with push rail, top vertical rod and latch assembly, ETB exterior escutcheon lever trim, and hex key dogging mechanism. Cylinder is not included and must be ordered separately.
