Sliding window rollers

Thank you for reaching out to us. It doesn't appear that we sell this exact roller. Our 81-229 is the first to come to mind though this has a 1-1/8" diameter wheel. If you think the specifications could work for you, the wheel can be swapped out with the 81-228 and 81-310 kit. 

We also have the 23-043. I recommend you review the specifications for each part to see if you think one of them could work for you.

Metal wheels are usually more rougher on the track than nylon wheels and are more prone to rust as well. Please note that the 81-229 is designed for sliding patio doors so we can't make any promises as to the functionality with windows. Our return policy can be found here.
