The U4400 EPDM is a lightweight rooftop attachment system consisting of an U-Anchor 4000 Series plate flashing membrane and separator disk. The U4400-EPDM provides a fastened, watertight, warranted attachment for EPDM single-ply membranes.
• Extremely strong and lightweight.
• Rapid installation.
U-Anchor Attachment

The U4400 EPDM is attached by fastening through the roofing assembly and into the structural decking with 4-12 approved fasteners, as directed by project specific engineering. The membrane cover and separator disk are then adhered in place and seam sealer is applied around the perimeter of the cover membrane and separator disk. Project-specific data is required to determine the correct type of fastener and number needed to secure each U-Anchor. An ANSI/SPRI FX-1 Pull Test is recommended to measure the pull-out resistance of fasteners included in the load path, (for example,substrate -> fasteners -> the U-Anchor -> other components.)
Equipment Attachment
To securely mount your rooftop equipment to the U-Anchor, after its installed, the connection nut must be tightened to approximately 20-25 ft.-lbs. Use a calibrated torque wrench during install to ensure appropriate
results are achieved. Refer to product documentation for detailed installation and component requirements.
Results are based on plate performance only.
