The Lindapter Hollo-Bolt is a patented method of securing to square, rectangular or circular hollow section steel, or to conventional steelwork where access is available from one side only. Awarded the Design Council's Millennium Products status for innovation in connecting to hollow section, the Hollo-Bolt also has third party endorsements from Corus and the UK's Steel Construction Institute.

The Hollo-Bolt offers a tremendous reduction in installation time and costs over

traditional methods, as well as giving the specifier absolute confidence through guaranteed loads with a built in factor of safety. For aggressive environments, the Hollo-Bolt comes with JS500 protection as standard and is available in stainless steel if the application demands.
