INSTáL III Bolt (.914" J-Bar®)

  1. Drill a 1-1/2" diameter hole approximately 1" to 1-1/2" longer than the bolt when completely assembled. 1-5/8" diameter borehole may also be used under certain strata conditions. Measure from where the plate touches the roof to the top of the bolt. Adjustment to be made to accommodate header boards, crossbars, plank, etc.

  2. Insert appropriate length and type of resin cartridge into hole (system adaptable to any length of resin).

  3. Insert the INSTáL II bolt into the borehole.

  4. With the bolt in the bolt wrench, raise to top of the hole. Just hold bolt snug against the roof and apply torque as specified in roof control plan (250-400 ft-lbs). Do not apply excessive up pressure with the boom of the bolting machine. Always keep hands away from rotating parts. This completes the installation
