Casement Window Operator Replacement

A quick learner from Bend, OR says:
Hi, I have vinyl crank windows and I would like to buy a casement window operator to replace the broken one that I have. Please see the photos that I have uploaded. The teeth on the operator are worn, and the window will no longer shut unless I take the screen out and grab it and pull it closed.

Hello there!

I recommend either our 39-253LB & 39-253RB or 39-438B & 39-439B operators. They look very similar to one another but the best match depends on what guide is used at the end of the arm. The video below will explain precisely what I mean. If you need a new cover and handle, see our 39-375 & 39-376 or 39-451 & 39-452 .
