SWIVEL SOCKET NOSE BOX

The Phillips Industries Sta-Dry S7 Swivel Socket Nosebox (part number 16-9510) is a 7-way electrical junction box that mounts on the front of a semi-trailer to connect lighting and ABS circuits between the tractor and trailer. The socket swivels 80° (40° each way) to follow the tractor's movement, reducing strain on the cable [phillipsind.com](https://phillipsind.com/product/sta-dry-s7/). It features an automatic disconnect that safely releases if the trailer is accidentally pulled away while still plugged in, preventing damage to the socket, cable, and tractor receptacle [finditparts.com](https://www.finditparts.com/products/4864570/phillips-industries-16-9510). The durable weather-resistant housing seals interior wiring against corrosion, chemicals, and extreme weather, and the box offers over 50% more interior space than standard noseboxes to keep wires organized and pinch-free [semitrailers.net](https://semitrailers.net/shop/phillips-sta-dry-s7-nose-box-w-swivel-socket-phl16-9510/). Replace your nosebox when the socket is worn, the housing is cracked, or you're experiencing intermittent electrical issues on your trailer.
