Split Set Utility Hangers can also make screen and mesh installation much easier, faster and safer. After your opening is secured with standard Friction Bolt, install the mesh all at once by driving friction bolt Utility hangers inside the tubes. No new holes are needed. There’s no awkward handling of mesh at the end of a long bolt, or under unsupported ground. Screen or Mesh conforms to the rock more tightly.

Hanger bolt’s welds quality is a also very critical point for the split set bolt which will affect the performance of the bolt while used in ground support. We have a routine quality mornitoring and warning system to get a consistance and stable perfect welds quality, and a job traveller with pull testing records will go through the whole processes to avoid any accidents in the production.

Hanger galvanizing and Black Split Set Bolt with different length are available. Made by high-grade of steel material, our split set bolt can get a very good zinc coating surface to have a better performance when it is used in corrosive environment.
