Welcome to our forum.
There isn't one...there's Two!What do you imagine those two BLACK FOAM FILLED NYLON DOOHICKIES conveniently placed at each end of the cover are for?
Drewstar, If you felt them you could tell that they are meant as a seal. With both sides of the loop together (as it would be with the cover closed) they are almost an inch thick!the main point being that in the original picture it appears as if there is a gap between the two sides of the cover....'Tis not the case, it is sealed.Would a linear seal be better? Probably. That being said the vast majority of Mfg. only have seals on the ends. As does Great Lakes.Peace Out
yep, I'm thinking HANDLES.....They didn't strike me as anything else......they're nylon webbing.EDIT: I'll check and recheck to see if they do anything.....however, I wonder what the actual level of workable insulation is in that cover, if that's all they provide.....I may get a second cover just for peace of mind.
Tatted Lady, Great Lakes tubs come standard with a cover that has a 4" to 2" taper. They offer a cover with a 5" to 4" taper as an option. We get an extra $150 for it. Ask your dealer.
Tatts, Tell your dealer to throw one in or no deal. He'll do it.
