Unique 27-E-50 Channel Balance

Quick Learner from Spring hill, florida
The block pulley broke on my channel balance. There is an ink stamp "(09/2)UNIQUE 27-E-50" on the back. The bar measures 28 inches long, is 9/16th wide, and is the plain design. Is the 770 28" Plain the correct bar to order?

Hi, Thanks for posting with images.
This does look like the 28" Series 770 balance. Please remove the window sash and place it on a scale. We need the weight of the window sash in pounds to determine the proper stamp option.
