28 9 ES CALDWELL

Question

I was looking at your
28" Series 351 Channel Balance
but I need to get the model that matches my units which are stamped "28 9 ES CALDWELL". The metal channel is 28".

Also, are your items better designed than my originals? They have cheap plastic rollers that go bad just sitting in the window.

Thanks

Hey there! Thanks for contacting us. Stamps ending in 9, like your "28 9," use an old rating system that has since fallen out of use. One of the more modern stamp options for the S351-28 will probably work, but you will need to weigh your sash on a scale to confirm.

Channel balances like the S351-28 should work for a good 5-10 years, depending on how often the window is used. There are no "better" made balances. They are pretty much all manufactured the same way.
