MB Rapid Bolt

MB Rapid Bolt safely and economically secures tilt-up and precast braces to the slab or other anchor points. It eliminates the inconvenience or uncertainty of cast-in-place inserts or expansion bolts.

MB Rapid Bolt is designed for quick and easy installation in single-use applications for tilt-up and precast concrete panels. 

 

 INSTALLATION INSTRUCTIONS

    1. 7” deep hole with hole cleaned to remove concrete fines.
    2. Drill through slab.
  2. Install the bolt through the brace shoe and drive the anchor down with a 200 FT-LB torque

WARNING: Over torquing can damage the anchor and reduce its capacity.
