Installation Instructions:
The NBLDN3 threaded adhesive anchor must be installed into a rigid, structural substrate that meets the project engineer’s specifications.
Layout & Pre-Drilling
- Mark all attachment hole locations on concrete
- Drill holes at each mark using a 1” diameter concrete bit to a depth of 5-1/4”.
- Initial hole cleaning: Insert the nozzle of an air compressor or air pump to the bottom of the hole and blow out debris. Repeat twice.
- Brush hole walls: Use a metal brush to scrub the walls of each hole, loosening any residual concrete. Repeat twice.
- Final hole cleaning: use the air compressor or air pump once more to remove any remaining debris from the hole
Epoxy fill
- Install epoxy into the hole per epoxy manufacturers guidelines
Installation
- Install NBLDN3 (internal threaded port side up) into the hole using a back & forth twisting motion to ensure complete coverage of epoxy until the top of NBLDN3 is flush with concrete surface.
- Let epoxy completely cure. Follow epoxy manufacturers curing guidelines.
- Install attachment into the NBLDN3 using a ½”-13 threaded rod or bolt.
- Ensure bolt is fully seated in the port without bottoming out
- Torque to 60 ft-lbs. using a hand tool only
- Medium-strength Loctite recommended
- Do not use power tools for final tightening.
