Our Through The Trapdoor ("3T") Industrial Scaffold Tower is the top selling tower in its class and the best on the market. Fully certified to the very latest BSEN 1004 British Standard and holding the BSI Kite mark - it is one of very few to have this prestigious award of safety. Importantly, the tower is manufactured in the UK by an ISO9001 licensed company and the quality of our product just can't be beaten. "3T" is one of the two methods of scaffold tower erection and dismantling recommended by the Prefabricated Access Suppliers and Manufacturers Association (PASMA) as well as the UK Health & Safety Executive. The other recommended method is Advanced Guard Rail (AGR), which we also offer.
