The product other name is split set stabiliser, it has only two parts-a tube and a bearing plate. The high-strength steel tube has a slot along its length; one end is tapered for easy insertion, and the other has a welded ring flange to hold the plate. With the bearing plate in place, the tube is driven into a slightly smaller hole, using the same standard percussion drill which made the hole. As the tube slides into place, its full-length slot narrows; the tube exerts radial pressure against the rock over its full contact length. Plate loading is generated immediately. The result is a tight grip which actually grows stronger with time and ground movement.
