Excalibur Scaffolding Ring Bolts 12mm

DETAILS

Excalibur Scaffolding Ring Bolts 12mm

The Excalibur Scaffolding Ring Bolts 12mm is used for the fixing of a vertical scaffold tube to a structure – safely, conveniently and securely.

A major advantage of this type of anchor lies in it being a once piece tie; when the project is finished and the scaffold struck, there is nothing left in the wall which may lead to further issues and the hole can be simply plugged.

During manufacture, the eye part is closed by a weld and when tested gave an ultimate tensile failure load of 50kN. With a suggested safety factor of 5:1, the SWL of 10kN exceeds that of the scaffold clip and is on par with the load imposed on a brick wall.
