ASC 12N 7-pin metal trailer socket
This ASC 12N 7-pin metal trailer socket is a proper, no-nonsense choice for anyone who tows a caravan, horsebox or trailer and wants something that just works. It’s made from heavy-duty metal so it won’t feel flimsy after a few trips, and the simple design means you plug in, lock it down and get on with your journey — no faff.
What it is
It’s a standard 7-pin 12N metal socket designed to take the common caravan and trailer 7-pin plugs. The locating slot (keyway) lines the pins up correctly every time, so there’s no guesswork when you’re connecting the electrics. A spring-loaded, weatherproof cover keeps water and muck off the contacts — pretty handy in winter or after a muddy field stop.
Why choose this one?
The metal construction stands up to day-to-day use and rougher conditions better than plastic alternatives. The keyway prevents incorrect fitment, protecting your lighting and signalling circuits from being misaligned. The cover closes securely to limit corrosion, so less maintenance and fewer surprises at the next MOT or on a dark country lane.
- Suitable for caravans, trailers, horseboxes and general towing where a standard 7-pin 12N socket is required.
- Built for regular users who need a tougher socket on utility trailers and commercial towing duties.
- Perfect for upgrading older, worn sockets that have become unreliable or rusty.
Practical details
Manufacturer: ASC — Manufacturer reference: ASC12nSocketMetal. It’s a metal-bodied 7-pin 12N socket with a locating slot to prevent incorrect insertion and a spring-loaded cover to keep the elements out. If you’re unsure whether 12N is the right type for your trailer or caravan, have a quick look at the vehicle handbook or ask the seller — but for standard lighting circuits (lights and indicators) this is the common choice.
Common concerns
Worried about fitment? The socket accepts standard 7-pin plugs, but mounting hole pitches and panel cut-outs can differ between vehicles, so check the measurements before drilling. Concerned about corrosion? The metal housing and cover significantly reduce exposure, but an occasional wipe and a dab of dielectric grease on the contacts will keep things tip-top for years.
All told, the ASC 12N socket is a straightforward, durable upgrade for anyone after a weather-resistant towing connection — less faffing about and more time on the road.
