Installation Instructions:
The NBLDN1 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
- Drill holes at each mark using a ⅞” diameter concrete bit to a depth of 4 1/16”.
- Hole cleaning: Insert the nozzle of an air compressor or air pump to the bottom of the hole and blow out debris. Repeat twice.
Epoxy fill
- Install epoxy into the hole per epoxy manufacturers guidelines
Installation
- Install NBLDN1 (internal threaded port side up) into the hole using a back & forth twisting motion to ensure complete coverage of epoxy until the top of NBLDN1 is flush with concrete surface.
- Let epoxy completely cure. Follow epoxy manufacturers curing guidelines.
- Install attachment into the NBLDN1 using a ⅜”-16 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.
