Sargent NB-8773 ETL Surface Vertical Rod Exit Device, Less Bottom Rod – Fail Safe Electrified Lever Trim, Non-Rated, Grade 1
The Sargent NB-8773 ETL is the less-bottom-rod (NB) version of the Sargent 8773 surface vertical rod exit device. It latches at the top only, into a 646 top strike. There is no bottom rod, bottom latch or bottom strike, so there is no floor strike to trip over. Fail-safe electrified ET lever: power off unlocks the lever. No outside cylinder. This listing is the non-rated panic device. The fire-labeled 12-NB sibling is a separate listing.
Institutional Grade Features & Benefits
- Fail-safe function 73: power off unlocks the outside lever. No cylinder on this listing. Inside rail is always free for egress.
- NB = less bottom rod: single-point top latching with the 646 top strike. Top latchbolt projection adjusts through the center case.
- Outside trim: 773-8 ET control with the L lever. The NB-8700 takes the -8 ET control trims, not the standard 8700 trims. This function has no outside cylinder.
