A quick learner from Country Club Hills, Illinois says:

Hello,

I'm looking to replace approximately 10 encasement operators from the attached photos (5 RT, 5LT)...I recently received an order fro swisco but they unit(s) do not fit.

Thanks!

Hello,
Have you seen the video below that demonstrates replacing the discontinued GU operator in your photos with our 39-315 and 39-316 operators that you purchased? I'm also curious about what you mean about them not fitting? Could you go into a bit more detail? Thanks you!

Aha! Thanks for the feedback....The video explains how to correct my issue; I just need to simply file the entry area that receives the operator.

Thanks.
