The MP1 Bolt is an encapsulated, end-anchored yielding bolt for mechanised installations. The end anchor provides immediate support upon installation with additional anchorage post-encapsulation of the installed MP1 Bolt.
To aid mechanised installation, the end anchor is shielded by a steel sleeve and is only activated once the MP1 Bolt is fully inserted into the support hole.
The MP1 Bolt can be supplied with Ø18 mm or Ø20 mm bar depending on requirements. The unit is provided with a load indicator to confirm correct tensioning of the unit when installed. The MP1 Bolt can accommodate a secondary push on or screw on mesh washer.
A specially designed system ensures easy mechanised or manual encapsulation of the installed MP1 Bolt with minimal spillage during pumping of resin or grout.
