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 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.
