Steps 1-4

The following assembly steps show two #10-32 bolts being used to mount the Tube Plugs. Additional bolts can be added and found here.

Step 1

Install a 1" x 1" Tube Plug into each end of the Horizontal Support Rails, secure them with #10-32 x 3/8"L bolts as shown below.

The Tube Plug may require light force to install. In such cases, a dead blow hammer or soft mallet can be used to gently seat the assembly into the tube.

Step 2

Install a 1" x 1" Tube Plug into each end of the Vertical Rails, secure them with #10-32 x 3/8"L bolts as shown below.

Only the Vertical Rails without pre-installed Rivet Nuts will have Tube Plugs at each end.

The Tube Plug may require light force to install. In such cases, a dead blow hammer or soft mallet can be used to gently seat the assembly into the tube.

Step 3

Install a 1" x 1" Tube Plug into the end of the remaining Vertical Rails, secure them with #10-32 x 3/8"L bolts as shown below.

Only the Vertical Rails with the pre-installed Rivet Nuts will have a Tube Plug on one end.

The Tube Plug may require light force to install. In such cases, a dead blow hammer or soft mallet can be used to gently seat the assembly into the tube.

Step 4

Combine the Vertical Rails from Steps 2 & 3 using the Horizontal Support Rail From Step 1, then secure them with #10-32 x 3/8"L bolts as shown below.

Repeat this for all of the Vertical Rails.
