You operator looks like an older version of the 39-014. However yours has a large nylon bearing at the end so you will need to replace the track with the 39-505 to fit the newer version bearing. I'm also not sure how well the 39-014 will fit in the sill trim, so keep in mind you may need to adapt the sill to fit the new style operator.

looking at the picture of the operator with the tape measure
if you look at the one on the left with a screw going down from the top is what i have. mine has a 9-1/2 " arm and a smaller one as well. its stamped bilt well on the top of both arms.but nothing anyplace else
is the single arm version mentioned 39014 my option?

If your arm is only 9-1/2", then I would recommend the 39-028E and 39-027E instead of what Dave recommended above. However, his warning is still in place. There's no guarantee that these will work, and if they can then it would likely require some adaptation. I'm sorry that we cannot offer a better match. |
