Square Pipe?
Flashers can be used on Square pipes also, to calculate which size is needed you multiply the dimensions of the four sides by 4 then divide the total figure by 3.142, see examples below:
Square pipe with 160mm faces, 160mm x 4 = 640mm divided by 3.142 = 203mm therefore a No. 6, 7 or 8 Flasher would be suitable but must be cut appropriately at the 200mm ring on the Flasher in this case.
