INSTáL 1A Compression Bolt (3/4" and 7/8" one-piece)

  1. Drill a 1-3/8" diameter hole approximately 1-1/2"-1" longer than the bolt when completely assembled. 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 resin cartridge into hole (system adaptable to any length of resin). Length and type of resin as specified in the roof control plan.

  3. Insert INSTáL 1A Compression* Bolt in the hole with expansion shell , support nut, mixing wedge, resin compression ring and adjustable clamp, optional anti-friction washer, hardened steel washer, and plate assembled on the bolt.

  4. With the bolt in the bolt wrench, raise to top of the hole. Just hold bolt snug against the roof while applying torque. Do not apply excessive up thrust when torqueing bolt. Always keep hands away from rotating parts.

  5. Torque bolt to 200-350 ft-lbs (3/4" system) or 250-400 ft-lbs (7/8" system). This completes the installation.

  6. *If using two piece (or more) INSTáL 1A, follow INSTáL II and INSTáL III Compression (3/4" and 7/8") instructions for coupled bolts.
