Replacement operator

A home owner from Colorado, USA says:
The name on the handle is "SEALRITE" The dimensions as best I can tell are 4&3/4" on the e3xterior arm and 5" on the inside crank. Numbers include 20755 on the upper arm and 31229 on the lower arm. Please not these pictures are for a window that opens to the left but the replacement I need is for a window that opens to the right. Thank you!

Hello,

I would recommend starting by comparing the dimensions of the 39-031 and 39-032 EntryGard operators to yours, paying close attention to the 4-7/16" length of the shorter link arm. Thank you!

The shorter link measures 3&3/4".Is that the length on the 39-155?

Thanks for verifying! In that case, yes, our 39-155 and 39-156 would be a better option for your window.
