Length of my Series 850

A home owner from Greensboro, NC says:
Order received, Thank You for the speedy delivery. Now, I remain confused about the parts they appear to be too short. On the part S850-16 your sent, from the bottom of the boot to the top of the spring, including the curved end, is 8 1/2" long.

Same measurement on the old part is 15 1/4".

The boot you sent is exactly what is needed.

I did find a Pat. # of 5737877 on the old part, same # is on the part shipped.

Also, do you have the metal pins that go on the bottom of window that fit into the boot?

Thanks for you assistance. jim blalock

Paul from SWISCO responded:
The way we measure our balance is from the bottom of the shoe to the very top of the assembled balance, not including the screw clip. What is that length on your old balance? That is the most important thing to consider.

The metal pin you're looking for is known as a pivot bar. We may have a match but there are a lot of potential options. Can you show us a picture of yours?
