Simplex 2975-9178 — red steel surface mount back box for 4099 Series addressable manual stations.
On block, masonry or any wall where conduit is run exposed, there is nothing to recess a pull station into, so the station mounts to this box instead. Simplex shows it as the preferred surface box for the 4099 Series: knockouts top and bottom for conduit, and enough depth for the station cover, which hinges open for wiring and for setting the address DIP switch.
- Surface mount steel box, red
- 5-3/16 in. H × 4 in. W × 2-3/16 in. D (132 mm × 102 mm × 56 mm)
- Knockouts located top and bottom
- For Simplex 4099 Series addressable manual stations: 4099-9001, 4099-9002, 4099-9003 and 4099-9020
Box only — the pull station is ordered separately. For threaded 3/4 in. conduit entries the cast aluminum equivalent is the 2975-9022; for a semi-flush retrofit to an existing two gang switch box, use the 2099-9813 trim plate instead.
