CONCRETE STUB TUBE

Data sheet DS48E

  • Ellis Stub Tube is designed to be placed over a bolt when pouring concrete slabs.

  • This forms a void, which then allows the bolt to move around once the concrete is set to make fixing steel structures in place easier.

  • The waterproof material means there is no distortion of the void which may occur if traditional cardboard tubes are used.

  • The addition of a lid also means it is highly unlikely for concrete to be accidentally poured into the void.

  • Once the steel is correctly fitted, the bolt remains firmly locked in place with the tube left in; it can then be filled with concrete or grout to be permanently fixed in place.

  • The stub tube is designed to accommodate a bolt up to M24 and be used at full size for 340mm fixings or cut down for 190mm fixings.

  • Manufactured in the UK from recycled, water-resistant polypropylene polymer

  • Part number BB-340
