Set of 10pcs White Window Sash Vent Stops 1720WHITE by Vision Hardware

This fit perfectly in my window frame and stops the window perfectly.

The windows that are home are probably about 20 + years old. The vent stops that came with them are thin, cheap, and brittle... Maybe UV weakened them but you can see they were cheap to start.The replacements seem to be made of a bolder more flexible material and will hopefully hold up. There were easy to install and work well. Compared to the original they are a touch of white, but my windows may have faded. Can't really tell and either way it's far better than a hole where the old ones were. Wish they were a bit cheaper but that's not much an issue.

I had a contractor redo the floors in my house so, naturally, they managed to break almost all of the sash stops in the house. Good times.These stops are solid, probably manufactured using a 3d printer-type process. I have no problems with that at all -- better them than me.They can be a little tricky to install. If you find yourself tempted to get a mallet to make 'em go, you're doing it wrong. Whatever seems like the right way to do it is the exact wrong way. Once you figure the trick out, they're painless to install.My biggest challenge with them is that there's no raised lip exposed when they're in the "allow the window to open all the way" position. So, I wind up trying to jam a fingernail under the end to pry it out. Maybe it's just me, but I find the sensation of prying them up with my fingernails to be unpleasant.All of that said, they fit perfectly, they're sturdy, and, again, they fit perfectly. (evidently my windows' stops are a less-common size). I would buy them again.

I'm so pleased with these window sash vent stops. The tenants removed the old ones when they left the apartment. Go figure!These stoppers were exactly what I wanted. They were easy to install, fit perfectly and work well.

I've been looking for these for years trying to find a replacement for the ones that were missing when we bought our house. They work perfectly very happy with the purchase

The media could not be loaded. Easy to install. Works perfect. The drafts that came through those little holes was insane. Now, all better

the tips bend up so it won't lock open... perfect fit but the material is not as strong as it needs to be

Worked great on our "Insulate" brand single-hung vinyl windows from the mid 90's. Exact fit. Whew!
