The Sargent NB-8715-J-ETL-84 is a heavy-duty surface vertical rod exit device engineered for wide, tall openings measuring 37 to 42 inches in width and up to 84 inches in door height. Built for passage function, it allows free entry and exit at all times, making it ideal for high-traffic doors that require reliable, non-latching operation. This configuration ships less bottom rod (LBR) for a cleaner floor line and reduced maintenance, and includes hex key dogging that lets you hold the pushbar retracted during peak periods. With ET control and the L lever design, it delivers smooth, dependable performance in demanding commercial and institutional settings.

Features

• Surface-mounted vertical rod exit device suited for wide openings from 37 to 42 inches.
• Designed for tall doors up to 84 inches in height.
• Passage function provides free operation with no locking on the trim side.
• Less bottom rod (LBR) configuration keeps the lower portion of the door clear.
• Hex key dogging allows the pushbar to be held in the depressed position for push-pull operation.
• ET control with the L lever trim for comfortable, code-compliant access.
• Robust construction built for high-traffic commercial and institutional environments.

Functional Details

The passage (J) function allows the exit device to operate freely from both sides. The lever trim always retracts the latch, and the pushbar releases the device from the egress side, with no locking engaged.

• Passage function – latchbolt retracted by lever from outside or by pushbar from inside at all times.
• No key required for operation.

Arm Type Details

This is a surface vertical rod device, meaning the latching mechanism runs vertically along the surface of the door rather than concealed within it. In the less bottom rod configuration, only the top rod engages the frame, simplifying installation and reducing wear points near the floor.
