I need to replace a Milgard window balancer for a non-tilting window. It's stamped 25 5 and no other stamps. It has winged ends. The channel is a 25 5/8" x 1/2". Sash weighs about 22 lbs. The bottom end is 1 3/32".
This style has the small metal piece that attaches to the end of the cord on the bottom of the balance.The U channel is overall 25 5/8". This measur5emnt doe snot include the plastic guides on the ends, just the actual metal channel.
