U-Anchor Attachment

The U1400-PVC is attached by fastening through the roofing assembly into the structural decking with 2-4 approved fasteners. The membrane cover is then hot air welded around the perimeter to the roof membrane. Fastener selection is dictated by the system assembly, deck type, and the project engineer. Refer to installation instructions and the specified roofing material manufacturer requirements before installing.

Equipment Attachment

To securely mount your rooftop equipment to the U-Anchor, after its installed, the connection nut must be fastened to approximately 20-25 torque pounds. Use a calibrated torque wrench during install to ensure appropriate results are achieved.
