I installed it myself and took me no time. I used a power drill for installation.

This was a perfect fit replacement for an OEM Milguard vertical sash, white vinyl window lock. The locking mechanism fit into the original holes, and there was no need to replace the second part (lock catch) as they worked together seamlessly. (The only identifying numbers on the broken OEM lock, other than the Milgard logo on the front, were on the underside: A-S PA)

works

Super-easy to install and is much sturdier (being metal) than the plastic flimsy stuff most vinyl windows come with.

Pretty solid. Not the exact shape I wanted as the holes from the previous window latch are still visible but awesome price and for some reason a very difficult to find item at hardware stores.

So glad I found these. I had been searching for the right size. This was exactly the right size, a perfect match!

Easy to install followed the holes that were drilled already. Will be buying a few more as backups

I live in a fairly new house and all the window locks were plastic. A couple broke and I decided to replace them all with these. I wasn’t able to install them myself as you really need a drill driver, which I don’t have, but it took my son only 30 mins to install 18 of them. I am very pleased that I can now open & close my windows without fearing that the lock will break.

Haven’t installed yet- not exactly what I needed. Mine is more square without the curve. Looks good for size. If it doesn’t work it’s my fault. I didn’t see exactly what I needed. The system is the same the shape is a variation. Will update if I install- still looking.
