1Before assembling the bench extension, layout and measure the 1.5" x 1.5" square tube lengths to verify
that you have all the correct tubes.
Determine the end of the original bench where the extension will be attached. Remove the Tek screws that
secure the Polymax® panel to the bench along this end. Remove any Tek screws that obstruct the 2-way
corner fittings of the original bench.
Carefully (and with assistance) flip the assembled bench frame onto its top. Locate two (2) 99" lengths of
square tube.
Slide the swaged end of the 99" tubes into the 2-way corner fittings and attach with a Tek screw.
NOTE: If the swaged ends do not fit entirely into the corner fittings, use a metal file or drill attachment to
smooth the pipe to receive the swaged end.
