39-253LB Question

Question

Yesterday, I tried to install my encore dual arm and discovered that the pin at the end of the long arm on the new part (see first picture) is just a tad smaller than the pin on the old existing part. When I try to insert the pin into the holder hole at the bottom of the existing window, the pin does not stay in & pops out. Otherwise, the encore dual arm is a perfect fit for old stripped part from my Milgard window.

Can you please recommend what I can do to fix this? Do you sell the holder hole part (see second picture, fuzzy, underside track of window) that fits the pin on the encore dual arm? Is this a part I can just buy at a local hardware store?

Thanks,
Tom

The track slider that works with our 39-253LB is the 39-529. It's possible you might be able to get the replacement operator to works by replacing the track slider. However, I should stress that the 39-253LB is often confused with another operator, the 39-438B. These two are practically the same, except that the 39-438B has a built in track slider that is more rectangular in shape. This is not interchangeable with the 39-253LB and 39-529. Now, based on your photos your old track slide does look more like the 39-529. But review the video below just to be certain.
