Patriot Window 9 1/2" Single Arm Operator

A contractor from Mclean, VA says:
I need to locate 6 left and 6 right 9 1/2" Single arm operators for a Patriot Casement window. I believe your items 39-365, 39-366 and 39-114L are the correct replacements, but wanted to make sure. We would like the best product that will last. Also, are there left and right handles? or do I order 12 of the 39-114L's?

Thanks for your help

Paul from SWISCO responded:
I agree with your assessment. Our 39-365 and 39-366 with stainless steel wheel bearings appear to be the best match. The handles do not come in left and right, so I would recommend either our 39-114L or 39-205 for both.
