We just used these for hurricane Matthew and they made boarding up (and unboarding) so incredibly easy! No damage to our windows that are only a couple of years old and no damage to our brick house. Awesome that you don't have to drill through anything. I would recommend adding these to your hurricane kit if you don't already have them. We used 4 clips per window.

These clips are a lifesaver for hurricane preparedness. They slide easily over the edge of the plywood and make it simple to cover windows without drilling holes. We have boards cut to fit our windows stacked in our garage and when storm season rolls around we simply slide the clips onto the edge of the wood and push the boards into the window and door frames. The "teeth" on the edge grab the frame and hold the wood in place.

I have bought and used this product in the past. Two Hurricanes so far in Houston, TX. No window problems.

If you live anywhere near a coastal region and had tropical storms/Hurricanes, you need this product. It is the only way to install plywood that fits snugly into a window opening without using screws or nails. Once you cut the plywood to size, install the clips on the edges of the plywood and push the plywood into the opening. It locks in place. Removing is also easy. Just pry one clip away from the window with a pry bar or large screw driver and the rest just pop off when you pull on the plywood. I keep the plywood in the garage up against the wall with the window location noted with a permanent marking pen, so I can use them over and over again.

Our 1st time to board up for a hurricane. Our boards were precut, so all we needed were the clips. They were sold out locally. Got them next day with Amazon Prime. The clips worked perfectly. We had our windows covered and secure in just minutes. These are the greatest invention! Have been able to return home yet due to the flooding Harvey has caused. We are hoping for minimal damage.
