Channel Balances, Series 350?

A landlord from Safety Harbor, Florida says:
I am interested in buying 8 # 2220 and 8 # 1620 1/2 channel Balances with top and shoe attached.

I am sending pictures to get the right top and shoe.

If you could please help me with this it would be greatly appreciated.

I think it is a 350 series but I am not sure.

Best regards
Robert V

Thanks for posting! Before I can offer any replacement channel balances for you to look at, can you first let me know what the length of the metal channel is for both of your balances? Please do not include the plastic attachments in your measurement.

the 2220 stamped on the side is 23 inches and the 1620 I think was 17 inches long without the plastic

Thank you. Please take a look at our S351-23 with a 2220 stamp option for the 23" balance, and a S351-17 with a 1620 stamp option for the 17" balance. Do you think these will work for you?
