FLEX TPO EXTENSION LEGS
PRODUCT DESCRIPTION
Flex TPO Extension Legs are designed for use with the Flex TPO Molded Sealant Pocket to extend the
sealant pocket by increments of ten inches. Fabricated from 45 mil thick TPO reinforced membrane and
TPO coated metal, the Flex Extension Legs can be used full length, cut to size for customized lengths or
welded to each other for extra long applications. They are packaged 10 legs per carton and available in
white.
PHYSICAL PROPERTIES

Material: Reinforced TPO membrane and coated metal

INSTALLATION
1. Clean the inside of the Flex TPO Extension Legs and Flex TPO Molded Pockets as well as the
areas where the pocket overlaps, the underside of the pocket flange and the deck membrane with
Flex Weathered Membrane Cleaner. Use a Primer Pad with the cleaner if the membrane has been
exposed for an extended period of time.
2. Place the Flex TPO Molded Pocket and the Flex TPO Extension Legs around the penetration(s),
overlapping the two sections of the pocket with the extension legs. The extension legs must be
positioned as follows: the two-inch TPO overlap tab is placed on the topside of the molded pocket
and the opposite end (with no welding tab) is placed on the underside of the opposing molded
pocket.
3. Cut a piece of cardboard (approximately 4” x 4”) and place it under the overlap area to be welded.
The cardboard prevents the pocket and extension leg from fusing to the deck membrane when first
welding overlaps.
4. Using a hand welder, weld the angle change in the overlap areas at each end of the extension leg.
Using the end of a seam probe assists in this process. (The hand-welder temperature setting
should be between 5 and 6).
5. Hand-weld the remainder of the horizontal overlaps.
