Sargent NB-8715-J-ETB-84 Surface Vertical Rod Exit Device, Passage Function, ET Control, B Lever, 37-42" Dr, 84" Dr Ht, Hex Key Dogging, Less Bottom Rod

The Sargent NB-8715-J-ETB-84 is a Grade 1 surface vertical rod exit device engineered for demanding commercial openings up to 84 inches in height and doors measuring 37 to 42 inches wide. Configured for passage function, it allows free entry and exit at all times, making it ideal for high-traffic corridors and non-latching applications. This unit features ET trim with the B lever design, hex key dogging for convenient hold-open control, and a less bottom rod (LBR) setup that keeps the lower door area clear while reducing maintenance. Built to Sargent's reputation for durability, it delivers reliable, code-compliant egress in institutional and commercial settings.

Features

• Surface-mounted vertical rod design provides secure two-point latching at the top of the door.
• Passage function permits free operation from both sides with no locking at the lever.
• ET control with the B lever trim offers a clean, ergonomic grip for everyday use.
• Hex key dogging allows the device to be held in a retracted, push-pull state for high-traffic periods.
• Less bottom rod (LBR) configuration eliminates the lower rod and latch for easier cleaning and fewer floor obstructions.
• Sized for doors 37 to 42 inches wide and up to 84 inches in height.

Functional Details

The passage function (NB prefix) provides unrestricted entry and exit with the lever operable at all times, suitable for openings that require free passage without latching the trim.

• Exit device is always unlocked, allowing free ingress and egress.
• Outside lever always active and does not control latching.

Arm Type Details

This is a surface vertical rod exit device, meaning the latching mechanism uses a surface-mounted rod running vertically to engage the top of the frame. In the less bottom rod configuration, only the top latch point is active, while hex key dogging mechanically holds the pushbar depressed for push-pull operation during peak traffic.

Included Components

The device ships with the 8700 series vertical rod chassis, ET-style outside trim with B lever, top rod and latch assembly, strike, and hex key dogging hardware. The bottom rod and latch are omitted per the LBR specification.
