Good Morning,
I am replacing channel balances on three, non-tilt single hung windows. The house is new to me but was built in 1982. I believe the windows are all Rollyson windows as they are etched with 'RO'. Unfortunately it appears as though some of the plastic balance shoes, balance tops, and top sash guides are broken but hopefully they can still be identified.
For two of the windows:
Channel Length: 29 inches
Channel Width: 0.5 inches
Balance Marked: '2830 B.S.I. MM'
For one of the windows:
Channel Length: 31 inches
Channel Width: 0.5 inches
Balance Marked: '3130 V'
I believe all of the channels use the same balance shoes and tops. From looking at your parts catalog, I believe they are close the following:
Possible Balance Shoe:
15-005 (Please see attached picture)
My only concern is that my max dimension is under 1". This seems shorter than the
15-005 but
closer than the 15-004.
Possible Balance Top:
19-037 (Please see attached picture)
However, instead of having a 'wingspan' of 1 13/32", mine is only about 1 3/16". I have
attached some pictures but it most cases, the 'wings' been snapped off. I measured the
1 3/16" from the window itself.
I will also need two top sash guides for one of the windows. I think they would be parts
18-123 and
18-124 but my example part is missing part of the plastic clip. (Please see attached picture).
Any insight you have on this would be greatly appreciated.
Thank you,
Adam
