| In a typical framing application, four End Clamps
are attached to two parallel bar joists or beams. Each End Clamp
slides over the top of the joist, occupying a space 1 1/4”
high by 3 1/4” wide between the joist and corrugations of
a standard roof deck. The bolt slots of the End Clamp hold Grade
5 carriage bolts captive while tightening the nuts. The slight slope
of the bolt slot counteracts any excess clearance, placing the clamp
system squarely on top of the joist. Combined with T-Brackets and
Perforated Channels, this system is ideal for the safe and economical
installation of exhaust fans, vents, sky lights, and roof mounted
air-conditioning units. |
