Prime-Line T 8500 3/8 In. x 2-1/16 In. Spring Steel Storm Window Snap Fastener (4 Pack)

These are great! They clamp down with a satisfying "snap" and hold quite a bit of weight, a surprising amount for their size. I have two on each of the heavy flipup gazebo window covers, and most of the time I only snap one of them because they hold so well. Very satisfied with this purchase.

Works great holding outside windows.

I used these to secure a storm window I made for friends. So easy to install (one screw). I saw a review that said they were difficult to snap. I didn't find them at all. They click in easily and strongly.

I put these up for easy removal of plexiglass windows. They work well. I've had to replace 2 that have come apart out of approx 56. Overall I give them a 4 with twice a year use and outdoor conditions.

Good product that is well made. Item was well packaged and arrived in a bubble envelope, well protected.

These were easy to install, we just needed longer screws to make sure they held good. We used these to secure our screens so our cats couldn’t push them out. We feel much better with these on our screens.

I thought these would be similar to the Wright brand, but these are smaller, and the "latch" part doesn't flip much; in fact there is very little play in the mechanism at all. This makes it hard to lift over the edge of the windows that I want to fasten down to the side of the house.

These were easy to install and work as expected
