Just wanted to make sure I'm ordering the correct part. The only markings on the old unit are the date on bottom "04/24/17 18:31 A" and "Truth" under the crank mechanism.
Do I need the left handed unit? Window opens to the left from the outside.
Thanks,
Janna

Hi Janna. This looks like the 39-253RB Dual-Arm Operator. This is technically the right-handed operator: Truth determines this from the outside of the window looking in. At any rate, you can tell it's the 39-253RB you need from the position of the spline the crank handle attaches to--it's on the left side of the operator body. With the 39-253LB, it's on the right-side.
For a new cover and handle, use either the 39-376 or 39-452, depending on the style you prefer. Also see the 39-529 Track Slide, which is sold separately. Let me know if you have further questions.
