Bbj h-frame bracket set 450x450mm feet b6089 As part of the expanding Big Foot range, the H Frame is a quick and economical solution for supporting pipework and ductwork. Using an insert, the foot adapts to accommodate 41 x 41mm off-the-shelf unistrut. You provide your own unistrut, keeping the duct and pipe installations low cost and totally flexible by fabricating the frameworks on-site. The H Frames are supplied with either 305mm2 feet (H: 75mm), or for larger scale installations (where a greater load spread is required) 450mm2 feet (H: 100mm). IMPORTANT: The purchaser or installer of these products must satisfy themselves that the roof structure is of sufficient strength to take the combined weight of the Big Foot System and units.
