Looking to replace Channel balances for a few windows
They all appear to be the same channel parts in terms of channel balance (although the windows are slightly different in width / weight)
The existing channels are:
29" Long
1/2" Wide (technically 5/8")
The measured depth of the bottom shoe (not the metal) is just under 1" (maybe 15/16")
The Windows range between 15.5# and 20#
The metal channel is stamped 28C
I see no other identifying marks
The windows themselves are Milestone Single hung Series 1000.
I am guessing the proper channel is
S380-29, and that based on weight I should get a set of Option 2830. That said, it's hard to be sure without any better item numbers on them. Please see pictures.
Any information or assistance is appreciated.
