4" and 5" Truss Kits for 40' Spans
Step 1: Locate the truss base assemblies (Ref #1) in the center of the tube that is to be trussed as
shown in Figure 1 on Page 1 . Be sure the angles on the base assemblies are oriented in the
same direction as noted. (See Figure 2 on Page 3.) Fasten the truss bases to the tube with
hardware Ref #2, #3 and #4. (See Figure 2 on Page 3.)
Step 2: Place truss braces (Ref #5) between the truss base assemblies and orient as shown. Attach
using hardware Ref #2, #4 and #6. (See Figure 2 on Page 3.)
Step 3: Position the cable saddle assemblies (Ref #11) and the eye bolt saddle weldments (Ref #7) on
opposite ends of the tube (See Figure 1 on Page 1) as close to the ends as possible but without
interfering with the compression couplers. Be sure to orient the saddle assemblies as shown in
Figure 3 on Page 4 and install with hardware Ref #4 and #6.
Step 4: Install the eye bolts (Ref #8) through the anchors on the eye bolt saddle weldments as shown in
Figure 3 on Page 4 . Make sure the eye is pointing toward the center of the tube. Fasten the
eye bolts using hardware Ref #9 and #10. Leave hardware loose for later cable adjustment.
Step 5: Run cables through the chain connectors on the cable saddle assemblies and fasten with
two (2) 5/16" cable clamps (Ref #13) as shown in Figure 3 on Page 4 .
NOTE: Secure the U-bolt of the clamps against the loose end of the cable.
Step 6: Loosen the 3/8" cable clamps on the tube base assemblies and route the cables through these
cable clamps to the eye bolt saddle weldments. DO NOT tighten 3/8" cable clamps at this time.
Step 7: Loop cables through eye bolts and fasten with two (2) 5/16" cable clamps (Ref #13) as shown
in Figure 3 on Page 4 .
NOTE: Secure the U-bolt of the clamps against the loose end of the cable.
Step 8: Using the eye bolts, tighten the cables to remove slack. Tighten all cables so they have the same
amount of tension. DO NOT overtighten. Sight down the tube to make sure it is straight. Once
adjustments are made, tighten the double 5/8" nuts (Ref #10) to lock the eye bolts in place.
Step 9: Tighten the 3/8" cable clamps that hold the cables to the tube base assemblies. Installation is
now complete.
NOTE: Saddle assemblies should be skip welded to the tube to prevent slipping.
