Window channel balance

Question

Hello,
I would like to buy two channel balances for one of my windows. I have attached pictures of both balances.
Currently I have balances with following specifications.
Metal channel width is 0.5 inches.
Metal channel length is 21 inches.
One channel has printed: “20 4 LR CALDWELL”.
The other has “20 4 CALDWELL HM”.

Thanks for posting. See the S380-21 or S385-21 Channel Balances. The difference is the depth of the bottom nylon shoe. See below. In either case, for a stamp option choose 2040.
