2.8. INSTALL UNIVERSAL CROSS BRACE
2.8.1.
Install universal cross braces on all support tubes when the walking surface is 72” or
higher above the ground. Cross braces are normally installed on all four sides unless two
platforms are connected.
2.8.2.
Use four braces per platform or six braces when two platforms are connected.
2.8.3.
Separate ends of brace bands until they fit around the 1-1/2” support leg.
2.8.4.
Install four bands on each leg with the part containing bolt holes at 90 degrees from each
other and in line with the outer edge of the foot (FIG. 2.21).
2.8.5.
The cross brace should be placed approximately in the middle of the platform legs on all four
sides with the top brace bands a minimum of two feet from the bottom brace bands.
2.8.6.
Install the cross brace by installing the 5/16”-18 x 1-1/2” hex bolt, 5/16”-18 hex nut, and
5/16” flat washer through the center hole in the braces. Tighten enough to hold the
brace together but still allow it to pivot around the bolt (FIG. 2.21).
2.8.7.
If needed for the location, trim the ends of the cross brace to fit.
2.8.8.
Drill one 11/32” or 3/8” diameter hole on center approximately 1/2” from both ends of
each brace.
2.8.9.
Install the assembled cross brace between the legs of the brace bands using the four
5/16”-18 x 1-1/2” long square neck carriage bolts, 5/16”-18 hex nuts, and 5/16” washers
provided (FIG. 2.21).
2.8.10.
Tighten all fasteners securely.
Ensure that all cross braces are secured before using platform.
