Windows Block and Tackle

A home owner from California says:
I'm looking for Windows Block and Tackle with shoe set.

On it it has the following marking -

29-5 KX CMC 7

My guess 29-5 translates to 2950 on your website and I'm thinking the following item is correct replacement -

30" SERIES 385 CHANNEL BALANCE
Product Code: S385-30

Appreciate if you can confirm before I place order for a pair of these.

Hello,

As long as your bottom attachment has the same 1-3/32" depth shown below, I agree that the S385-30 with a 2950 spring strength option would be the correct replacement. If the depth is 1" exactly, take a look at the S380-30 instead. Thank you!
