NON-TILT WINDOW CHANNEL BALANCES for Rollyson Series E-500

A home owner from Middletown, Maryland says:

I have four windows that I need to replace the channel balances for. The stamps are 3410 and 2810. I don't not see anything on your site that references those numbers or the series number, but I did notice that the Series 370 looks very similar..

Any help is greatly appreciated.

Hey, Seth. I agree, our Series 370 looks like a close match. The stamps aren't any kind of identification number, they just help you know what the strength of the springs are.

Just double check that the nylon attachments on the Series 370 match your own as closely as possible.
