Sargent NB-8715-G-ETB-84 Surface Vertical Rod Exit Device, Passage Function, ET Control, B Lever, 43-48" Dr, 84" Dr Ht, Hex Key Dogging, Less Bottom Rod

The Sargent NB-8715-G-ETB-84 is a heavy-duty surface vertical rod exit device engineered for dependable performance on wide, tall openings measuring 43 to 48 inches in width and 84 inches in height. Configured for passage function, it allows free entry and exit at all times, making it ideal for high-traffic commercial and institutional doors. This device pairs with the ETB trim and B lever for intuitive operation, while hex key dogging lets staff hold the latch retracted for continuous push-pull access. The less bottom rod (LBR) design reduces floor-level obstructions and simplifies maintenance, delivering a clean, reliable solution for demanding environments.

Features

• Surface-mounted vertical rod construction built for high-traffic commercial applications.
• Passage function provides unrestricted entry and exit through the opening.
• ETB trim with B lever design for comfortable, code-compliant operation.
• Sized for doors 43 to 48 inches wide and 84 inches tall.
• Hex key dogging holds the latch retracted for push-pull convenience.

• Durable finish options to match a range of door and hardware aesthetics.

Functional Details

The passage function allows the door to be pushed open from the inside and pulled open from the outside at all times, with no locking at the trim. Hex key dogging mechanically retracts and holds the latch, keeping the opening in a free-swing state for periods of heavy use.

• Passage function - latch retracted by lever from outside at all times.
• Hex key dogging allows mechanical dogging of the push bar for push-pull function.

Arm Type Details

As a surface vertical rod device, the 8700 series uses top and bottom latching rods mounted to the face of the door. In this less bottom rod configuration, only the top rod and latch engage the frame, reducing wear points and floor-level maintenance while maintaining secure top-latch performance.

Included Components

This device ships with the surface vertical rod exit mechanism, ETB trim with B lever, top rod and latch assembly, strike, and mounting hardware. The bottom rod and latch are not included per the LBR designation.
