Hello:
Hopefully, the attached photos (5 of 7, 2 more to follow) will assist you in identifying, with specificity, what I believe to be are 4 (four), 25 inch long (by their metal sleeves), 3/8" wide (by their metal sleeves), Non-Tilt, with a Clear/Yellowed top cap/plug, spiral sash support balances.
When I removed each one of these 4 balances, from their positions, on each side of the two windows, to which they had been installed, there was an extremely thin, white plastic covering tube present, that covered the full 25" length of each balance's metal sleeve. Each of these extremely thin plastic covering tubes fell off, broke away, chipped off, or simply dissolved and fell off, from the grease present on them along with their age (I believe these windows are original to the house and that they were Installed in or around the year 1955.
In an effort to restore the thin plastic coverings of each of these balances, I inserted each one into a 25" length of 5/8" PEX plastic tubing. All seemed fine until I attempted to reinstall them into their original positions.
Despite my taking into account, that the thickness of the PEX tubing, would increase the size of each balance's metal sleeve width from 3/8" to 5/8" wide, each of these restored balances turned out to be JUST a hair too wide, to allow them to function properly. Hence, the need to identify and replace them.
I would like to identify and purchase:4 25" spiral sash balances
4 Sash-Bottom Clips (I'm fine using the old ones. However, each is riveted to the old center spiral springs. While I could liberate each of them undamaged, I would have to manually rivet each of them onto to the new balances I purchase from you. At which point, it's probably smarter to simply replace and attach new one from you, using an updated method of attachment, no?
4 1" to 1.5" Phillips screws, with which to attach the four new balances, to the old window frames.Each old wooden window sash, is rather heavy because I replaced each of their 6 window lites with extra thick glass, and each sash meets some resistance from what appears to be aluminum lining and track, that lines the inside of each spiral balance pocket. Therefore, the rating of each spring you choose should be heavy duty enough to lift considerable weight.
If possible, I'd like to place this order on your website today, along with the appropriate non-tilt charging installation tool (~$12.00). 2 additional photos will follow this request and I'll call in shortly after your receive both emails in the hope we can resolve the identification issues that will enable me to place the above mentioned order. Thank you
