Extend-A-Snap, 4-Pack - Handi-Man Marine

saved me the cost of replacing boat cover

I purchased these snaps because my boat cover had shrunk and could not snap some of the snaps. Since using these extend a snaps they have either torn or broke using vey little pressure. The material used for these snaps need to be made with something stronger. If you purchase these make sure you buy about 3 times more snaps than you need because you will go through all of them in a summers time.

Absolutely genious! Never knew this product existed until found it on the internet. Works great. Wish I had found it sooner. So simple and yet so helpful.
