New Top Sash Clips

A contractor from Ohio says:
I am in need of replacement top sash clips for a customer of mine. The windows are for an apartment complex, they are aluminum double hung windows. I have previously purchased Series 390 Channel Balance for the windows but now they are in need of these clips. I looked at the recommended clip and the measurements and profile does not match up. Did the design change or something? Any help you could offer would be greatly appreciated.

Hello! Take a look at our 18-159P top sash guide and see if this is a good match.
