Pair of non-tilt channel balances needed -- PART 1

Hi,

Home owner looking for a pair of non-tilt channel balances as replacement for a broken one. I have looked at your series 380 (S380-29) 2870 for 40# sash as a potential. I have included data below and images of balance parts for your team to check for the best fit. The only exception to the measurements of your 380 series appears to be the depth of the shoe (15-005) at 1 inch which is about 1/16 off what I measured on my balance. Probably insignificant -- maybe? And I don't know how much slop there is in the making of the windows to make an educated guess.

I have not been able to find information for the identifier (05/10 UNIQUE 28-F-60). If "60" means 60#, why use it for a 40# sash -- over kill? We have noticed these windows particularly hard to open/close. Would appreciate knowing what it means for my records. Please email if you need other information or images.

Hoping to hear from SWISCO soon. Thanks in advance and have a pleasant day.

Hi,

Due to the limit of images allowed, this post includes the rest of images for post D289461. Again, have a pleasant day.

Thanks for the quick response. I am unsure the 7/8 would be a good fit. Is it that SWISCO does not offer or have in stock a 5/16 inch depth winged shoe? I noticed you stock Rollyson items. There is a Rollyson item 60-904 on the net that is 15/16". As they say in the measurement world -- you can take some material off if necessary, but you can't add it back.

My initial measurements were referenced off a standard school ruler -- not the best. This time I used my digital caliper and the results are closer to the 15/16 inch than the 7/8 inch. Anyway, below are the latest data.

New measurements:

Equivalent for 15/16 -- 30/32, 120/128; for 7/8 -- 28/32, 112/128.

shoe #1 -- 119/128 both sides
shoe #2 -- 29/32, 17/128
