Non-Tensioned Headed Rebar or J-Bar®

  1. Drill appropriate diameter hole 1" longer than the length of the bolt. Measure from where the plate touches the roof to the top end of the bolt.

  2. Insert the appropriate length resin cartridge(s) into the drillhole. Care should be taken to insure the resin cartridge is not broken before inserting into the hole.

  3. With the square head of the bolt in the bolt wrench, push the bolt into the hole and through the resin cartridge.

  4. Once the bolt is completely in the drillhole, and with the plate slightly off the roof without excessive upward boom pressure, rotate the bolt rapidly to mix the resin. Always keep hands away from rotating parts. Rotate for amount of time as specified for type of resin used.

  5. When the proper mix time has been achieved, stop rotation, thrust the head of the bolt with plate tight against the roof using the bolt machine boom pressure. Hold tight against roof until resin sets up as per time specified.

  6. Once resin hold time is achieved, installation is complete and wrench may be removed from bolt. Do not attempt to rotate bolt once resin sets up.
