Expansion shells of ø36 mm are the elements which set the bolt in the hole. The KE-3W shell consists of 3 shells and one expander while the KE3-2K shell consists of 3 shells and 2 expanders.
Simple and easy to install for immediate support to a work area, the expansion shell creates a point to anchor into the hole by turning the bolt. The shell tightens to the rock creating tension at the foot of the borehole, transferring the load from the bolt head and plate to the rock via the shell.
