LOKSET RESIN CAPSULES

The Lokset resin system provides rapid anchoring of the bolt to the surrounding strata. The rotation of the bolt during installation ruptures the capsule, shreds the skin and mixes the two components transforming the resin mastic into a solid anchor. Resin point anchoring and bulbs to assist resin capsule mixing.

Packaging

Bolts are usually packaged in bundles of 50 or 100. Coiled or flat bundle options available
