1 purchased the 1-1/4 inch size. When you compress the fabric it widens a bit. It did take a little time to feed the hose through the sheath because as it is stretched, it wants to grab (shrink). Once I got the hang of it (compressing it as I was installing it) the job went fairly quickly. You must cut any excess nylon fabric with a hot knife or an old junk knife that you heat up with a propane torch (my method). Once the fabric has melted on the knife, it is very tough to get it off. The ends are just attacked with a band clamp (I thing a zip tie pulled tight might work also).I assume you want to use the smallest diameter sheath so you can fit it all back in the wet bay. So I gotta ask, was it very hard to fish that limp noodle thru the sheath?
