Window Part

To whom it may concern,

I'm looking to replace the part pictured below. It's the slider mechanism from a glass patio window, and dates to the 1980s.
The part is marked "Allen Stevens Corp" "Woodside, N. Y.", with a circle that has the numbers "60" over "49" in it. The piece with the wheel attached has the number 6047 stamped into it. You should be able to zoom in on the photos for more detail.

I'm hoping to purchase four of these.

Thank you in advance for your help.

Hello there!

Thank you for reaching out to us. I'm afraid Allen Stevens is no longer in business so we don't sell this roller. However, the good news is that you can use the 81-005 to replace it. Take a look and let me know if you have any questions.
