Eco Fasten GF-1 Complete Mount and Flashing Assembly

GF-1

GF-1 FLASHING GLV MLL 8X12″ GALVALUME FLASHING WITH PREINSTALLED EPDM RUBBER GASKET

(AVAILABLE IN 8X10 & 8X12, WITH MILL & BLACK FINISH OPTIONS)

INSTALLING GF-1

Snap horizontal lines across the roof to mark the mount rows, then locate the rafter and mark the installation position of each GF-1 flashing.
Drill a 7/32″ pilot hole into the rafter or structural member for the lag screw. Backfill with sealant compatible with the roof type.
Slide flashing up under the next row of shingles directly above the pilot hole, taking care to align the hole in the flashing with the pilot hole.
Thread the EPDM bonded washer onto the lag bolt followed by one of EcoFasten’s compression brackets and then insert the lag bolt into the gasketed hole in the flashing.
Drive the lag bolt down into the rafter using an impact driver. Torque range is between 100-400 torque inch-pounds depending on the type of wood and time of year. The visual indicator for proper torque is when the EPDM on the underside of the bonded washer begins to push out the sides as the washer compresses. Do not over torque.
