Window Lock Replacement

Home Owner from Brookline, MA
Hi there,

I just moved into a new house, and many of the window locks are broken. Unfortunately, I have no idea what kind of windows these are. I need at least 11 replacement locks, and possibly more. Ideally the replacements would be more durable than the originals, which snap off at the least provocation.

Please have a look at the attached photos, and let me know what you think. The lock is 2.5" long. It's harder to measure its width because the measurement varies depending on where you choose to put the tape measure, so I won't include a measurement for that. It is 7/8" tall. The part you push with your thumb to lock the window is 2" long.

It's 2" or 2 1/8" from one screw hole to the other.

The part that the lock locks into is 2.5" long and 1/4-3/8" wide.

Thanks,
Karyn W

Thanks for posting, Karyn. There's a big difference between 2" and 2-1/8". Can you confirm the hole spacing? Make sure to only measure from the center of each hole, not the edges. That gives a more accurate measurement.

I'm thinking it might be 2-1/16". Check out our 90-077A and 90-177, or perhaps our 90-161.

Thanks for your help.

I have found it hard to measure between screw holes because the thumb piece is in the way. Lucky(?) for me, one of the locks has the thumb piece broken right off. So I laid a piece of paper across it, put a dot in the center of each screw on the lock, and the measurement is 2-3/16". Do you have anything that would fit that distance between screw holes?

Thanks!

I'm afraid we have nothing in that style that's that big. Can you confirm that measurement?

You can probably just turn the lever aside for an accurate measurement of the holes.
