Schedule 40 PVC tube. The tube must be a single, contiguous
piece, capped with a commercial PVC pipe cap cemented at the
bottom end.

Please note that the flag holder must be 12" long, Schedule 40 with a pipe cap whose top end is 51" above the floor +/- 1". Mounting holes are acceptable but are under the scrutiny of the Robot Inspector. Further, the flagholder must allow for a two inch radius of at least 180 degrees for the lap indicator to be visible from above. The lap indicator does move a bit during robot operation. The rule this year is specific and does not provide for deviation in design.

If I can add my $.02. 1/2" Sch 40 pvc has an ID of 3/8", NOT an ID of 1/2". (It's a construction thing.) Make sure the printed labeling on the side of the sch 40 says 1/2 inch.
As far as mounting, 2 hose clamps work well wrapped around a piece off 1" x 1" alum angle thats bolted to a structural member.
