My block and tackle balance is 28 inches long and stamped 28B but the top end has a 1/4" wide hook attached to the string. The hook engages a 9/32" hole near the top of the window channel.
>> Do you have a model with a hook or do I untie my hook and use it?
My "pivot bar" also looks different from 26-021 shown on your site.
>> Do I re-use my pivot bar? The end looks like 26-021 and should engage 15-195 t-lock balance shoe.
Photos are attached.
Thanks for your help,
David
