Alloy:
6062T6
Outside Diameter:
7/8
Wall:
.120
Part number:
03-36500
Length:
4
Quantity:
2
(I ordered 2 x 4 foot lengths instead of one 8 foot length so it can
come via regular UPS and save $.)
My order cost me ~30 (don't know what shipping is, I figure $10 at
most). So I got 8 clipon tubes for ~$5 a pop. (Standard clipon
tube u can buy is 9 inches, so take a 12in length and cut it to size)
Enjoy!
