Step 1 – Combine Extrusions
Thread threaded stud into center hole of one end
of one extrusion. Using either a cap nut or two
nuts on the end of threaded stud will aid in
threading the stud into the extrusion.
Screw the other extrusion onto the other end of
threaded stud.
Slide two 5/16” x 3/4” carriage bolts into the end of each rail.
Set the splice plate over the four carriage bolts.
Using four 3/8” washers and four 3/8” lock washers, fasten the splice plate to the extrusions. Be sure the
splice plate is centered over the two extrusions.
Tighten.
Repeat for other two extrusions.
