i live in an apartment and the fools here want to call a contractor and come and fix this because they don't know how. and they are paid well on top of that. it took me a minute to pop the window out. the so called tech didn't know what to do. he doesn't know what he is doing and is employed. i know what i am doing, and am unemployed. go figure. i'll repair it myself and give them the bill.
the 5/8 aluminum one looks like it would work, except mine only has one screw hole not 2. are these guides available at lowes/home depot, or are they your design?
I'm having trouble finding a closer match. Could you give us your exact dimensions? I'd like to know if they differ in any other way.
