Pivot lock

A quick learner from NC says:
I need to replace the pivot locks on my windows. Attached are pictures. They measure 2 inches tall 1 1/4 inches wide and 1/2 inch deep. There are PAT# D467490 on the top of the pivot lock and #4810108 on the bottom of the pivot lock. Any help would be appreciated.

Hello,

Your T-Lock shoe resembles the open cam 15-195B, which is used on our Series 795 tilt window channel balances. We'll include the dimensions from our product page below. Take a look and let us know if you have any other questions. Thank you!
