Hi, Steve. I believe you have a match for our 39-253LB operator. Ours is the newer Encore style that Truth makes, which means you'll also need the 39-451 handle/cover combo that is sold separately. One thing to note is that the 39-253LB has a peg on the end of the arm that plugs into a square black guide in the window track. There is another version, the 39-438B, which has a small rectangular guide riveted to the end of the arm itself. I know it seems like a small distinction, but it is important. I can't see the end of your arm in your photos so you should check that detail before you purchase anything. All you need to do is see if the guide is a square or rectangle. |
