Rubber 5/8 tube holder? spacer?

Question

Hello Swisco,

I am not sure what the part is called and whether it is necessary, but the 5/8th tubes are held in position by a square rubber spacer with a hole for the end of the tube? If you have an idea that would be great.

Thanks in advance,

Pete

Hi Pete,

Take a look at the 26-139, single hole aligner.

Honestly, I'm not so sure how necessary they are but if they were installed originally I think it's a good idea to replace. I believe some window manufacturers used them to keep the balance centered and taught as the sash slides up and down.
