Spring loaded handle 4" long x 5/8" diameter, 1-5/16" wide (NOT including 1/8" locking tab in center).

A home owner from Rancho Cordova, CA says:
Dimensions are under "subject". Final picture shows all 5 parts. The 1/8 inch thick by 1/4 inch square nut engages a slot in the sliding window frame and the spring pushes the locking tab into a slot in the fixed window frame. I have included photos per your request. I am looking for 3 complete assemblies with all 5 parts as shown. I could find no visible markings on the device.

Hello!

Our 90-315 was the first part to come to mind. Take a look at the specifications and see how they compare with yours.

Let us know if you have any questions!

Hello Emily,

Regarding Discussion #290087

Part # 90-315 looks promising, but I have a question about the difference in its curved handle or "grip", which is different from the round handle on the ones I'd like to replace. I'd like to be sure that the difference in the grip is strictly cosmetic rather than functional. I have added a photo to show the round handle.

We don't sell this exact style but it is our best option. As long as the specifications match up, you should be good to go!

Emily,

90-315 latch is good but as mentioned in this thread I dont see locking tab. Is this latch comes with locking tab?

Thanks

I'm afraid I'm not sure what you mean by locking tab but see the image below for how this latch is configured. Let us know if this helps.

I am looking for this part. This is locking system front and back. If you have that then I want to buy.

Thanks for the photos. We don't sell a match for this part, unfortunately. Your best bet may be to contact the original manufacturer of the window if they're still around. I am very sorry for the inconvenience.
