Thank you for posting! I'd be happy to tell you the difference between these color shoes, but can you first tell me what the length of your balance is?

It's not a matter of which shoe is better--each shoe is made to work with a very specific window sash weight and jamb width. You will needs to make sure that your sash weight matches the weight capacity of one of these shoe options, and that the shoe width will fit in your jamb.

The window sash weight ranges for the S850-26 shoes are as follows:

Black 1-1/4": 7 through 19 pounds
Black 1": 7 through 19 pounds
Red 15/16": 17 through 19 pounds
White 1-1/4": 19 through 24 pounds
White 1": 19 through 24 pounds
