Hi,
I need help finding replacements for 2 different sets of channel balances.

The first one has a 30" length and a 9/16" channel width with markings "29DS_48L BSI RN"

Hi,

I need help finding replacements for 2 different sets of channel balances. I've made a separate post for the first set.

The second set has a 36" length and a 9/16" channel width with markings "35DS IMP 37 BSI R"
(Last 4 photos)

These channel balances support very heavy windows with Hurricane glass.

Thanks!

Hello! I think we can replace this hardware, though they will need to be custom made. To confirm, I would like the weight of the sash each pair of balances support. Please let me know that and we can work from there.
