truth entry gard operator

Thanks for contacting us. I'm afraid we don't have a casement operator track in 13.5". The best match we have is our 39-505, which is 11-3/8". Is this something you could use? It's designed to work with our 39-031 and 39-032 operators, which I think will also match what you have in your photos. You should go over our dimensions just to be sure they match. 

Some other parts you may want to look at are our 39-107 cover and 39-115 knob.
