Attach the Flanges (683-102HC) to your wood piece using wood screws.
Make sure that you are spacing the Flanges (683-102HC) enough so the 6" pipe can fit in between them.
Stage 2
Installing Locker
Slide a 6" pipe into each Flange then tighten set screws.
Attach the bottom of a Single Socket Tee (680-102HC) to each end of a 6" pipe. Make sure the vertical holes are not being blocked then tighten set screws.
Slide the pipe, with the Single Socket Tee's (680-102HC) at the end, down the vertical pipes. You will not be tightening these set screws since this bar will be your holder for the napkins.
