Installation Instructions:

Layout & Fastening

• Layout NBE & attach to the form for desired location & height prior to concrete pour.

• Install port protection caps if you are not using the port to attach NBE to form

____________________________________________________________________________

 Concrete Pour

• Pour concrete & embed NBE. Do not allow concrete to cover the top NBE.
• Let concrete cure according to manufactures guidelines
• Remove form and place port protection caps in port of NBE to prevent contamination of the internal threaded port on NBE

____________________________________________________________________________

Surface Prep & Waterproofing

• Scarify and apply waterproofing each NBE anchor mount per the waterproof flashing manufacturer’s recommendations to improve adhesion.
• After waterproofing has cured, cut out the port protection caps to expose internal threads

Washer Placement and Reassembly

• Place a minimum 1/16” thick washer over each NBE port so that the washers sit directly on the waterproofing membrane.
• Use a washer with an ID size of at least ½” around the internal port of the NBE.
• Attachment should never sit directly on the waterproofing.
• ½”-13 bolt for attachments
• Ensure bolt is fully seated in the port without bottoming out
• Torque to 60 ft-lbs. using a hand tool only
• Use a level and structural shims if necessary
• No power tools for final tightening.
