Hi,
I bought S140-20 balancer (quick-Tilt, dual) that do not fit to my window. It is wrong size and wrong type. I may have to return them (order number is 1283475).
I took the old balancer out per attached picture.
I saw number like 1. 5353.5. The size is 100 mm (3.937") long x 30 mm (1.181") wide and 12 mm (0.492") thick.
Can you help to select a right part to use?
Thank you and best regards,
Jason
