Details
Solid - KnuckleHeads adhered with M-1 prevent water, ice and dirt from underriding support and attacking roofing membranes. Bonded KnuckleHead support systems minimize damage by wind, ice, flying debris, vandalism and seismic events. KnuckleHeads help disperse weight to the desired points along the bonded structure. Small membrane pads may be used to further disperse the weight.
Durable - KnuckleHeads are impervious to water, biological attack and freeze-thaw conditions.
Versatile - The adjustable KnuckleHead easily raises and lowers from a height of 3 1/8" to 4 1/8", usually eliminating the need for a riser. It accommodates two ½" diameter pipes in small channels, or a single 1" pipe in a large channel.
