A quick learner says:
Let me know if you need anything else to help me locate these parts. Thank you very much. I would need both a left and a right side.

Hi there, Claude.

According to our records, the parts shown here are no longer made. Our Series 140 would be our recommendation, however. This is 9/16" thick and 1-1/4" wide. Take a look and see what you think.

If you have any questions just let us know!

So is this a series 140 single coil?

With a 9-pound sash, you can use the S140-5. A pair of these will support a sash weighing 9-10.99 pounds. We also sell the S140-4. A pair would support a sash weighing 7-8.99 pounds but there's a chance this may not be strong enough for the sash.
