Installation Instructions:

Substrate Requirements

• The NB3CC fastener must be installed into a solid substrate that meets the project engineer’s specifications.
•  Approved substrate: Concrete

____________________________________________________________________________

Layout & Predrilling

• Mark out NB3CC fasteners to the desired attachment locations on the already waterproofed or membraned surface.
•  Predrill marked locations using: ½” x 3.25” long drill bit.

• Hole cleaning: Insert the nozzle of an air compressor or air pump to the bottom of the hole and blow out debris. Repeat twice.

Waterproofing-Sealing

• Apply sealant in and around predrilled hole according to roofing manufactures compatibility guidelines

____________________________________________________________________________

Installation & Attachment

• Drive the NB3CC into the predrilled hole using a 5/16” allen key bit until the flange compresses directly on the waterproofed or membraned surface creating a gasket seal.
• Bolt the attachment into the internal threaded port on the NB3CC with ¼”-20 bolt using a hand tool only
• Ensure bolt is fully seated in the port without bottoming out

• Do not use power tools for final tightening of attachment.
