1
Mark off all measurements on floor using blue chalk line. (Measurements
are included on project drawings.)
2
Project chalk lines from the floor to the roof members using plumb bob or
laser plumb pointer.
CAUTION: All measurements indicate center of clamp. Don’t forget
to add or subtract distance to clamp edges when placing clamps.
3
Attach clamp assemblies to roof structure (use numbers on project draw-
ings to cross reference figures below). See Fig. G-1 and Fig. G-2 for tips
on beam and tube mounts.
Please Note:
Make sure all bolt and screw heads are toward the floor
(threads pointing up).
4
Place superstructure tubing into clamp assemblies, insert cap screws,
and start nuts.
Please Note: All superstructure must be plumb and level before
attaching T-Frame.
5
Tighten with impact tool. All Progressive Sports Construction Group
Gymnasium Equipment is supplied with Grade 5 hardware. Clamps are
designed to be installed with the nuts and bolts “tight.” Progressive
Sports Construction Group would consider tight to be torques between
40 ft-lbs and 60 ft-lbs.
