Looking for a replacement operators both left and right hand positions for 2 late 90's Certainteed casement windows. I think you have what I need but could use some advice on picking the right ones. Please list the parts I would need to replace both entire assemblies. Thanks.

Hello,

Your operator resembles the 39-253LB & 39-253RB or the 39-438B & 39-439B. The determining factor would be the guide used at the end of the straight arm. See our video below to choose the correct replacements. Thanks for posting!

Thanks for this info. It was tough to get a good picture but I believe the ones I need in right and left hand operation are the 39-253LB and 39-253RB, along with (2) of the 39-529 glider clips. Do you agree? Thanks.

I agree that your photo resembles the 39-529 slider used with the 39-253LB and 39-253RB but you'll ultimately need to detach it from the track to confirm the specifications below match up to yours.
