EX BT Openreach Box mounted on a Braked Galvanised Trailer. As far as I know this box is in as original specification as supplied to BT. I have had it for about seven years using it mainly as makeshift storage when having my house extended so can vouch for it being waterproof. Everything in the photos relating to the trailer are included like the tow ball lock, wheel clamp, extension towing mirror for a car and yellow metal rear step that came with it. I have keys for all the locks with the exception of the white safe box in the photos. I used my own 7pin light board when I bought it which is still attached and it tows well including empty when I bought it and full with approximately 1tonne. External Dimensions 14ft 9 Long Inc. Hitch / 7ft Wide – 7ft 6 High. Internal Dimensions 10ft Long / 6ft 7″ Wide – 6ft 2″ High.
