A note about biminis: Generally speaking, these bimini parts are made to be used with standard aluminum or stainless steel tubing in 3/4" and 7/8" sizes. Other materials such as electrical conduit or pipe can sometimes be used but the fit will not be ideal and you will have to shim or grind as necessary. Tubing is designated by its outside diameter while pipe and conduit are designated by the approximate inside dimension.
