Truth roto

A quick learner from Edison, NJ says:
I have an old casement with Truth Roto hardware. The plastic pivot piece that slides in the track broke. The second, shorter arm appears to be a travel limiter. It has one on top and one one the bottom of the sash and they appear OK.


Jamb mounted track: 9 1/2"
Sash mounted track: 12"
Off set shaped arm from the crank assembly: 7 1/2"

The crank housing is 5 1/2" wide. The screws, as viewed from outside, have two screws together on left and one on the right. The distance at the outermost screws is 4-1/4". I see no other markings besides "Roto" and "Truth".

Thanks for posting, Jon. Looks like the plastic slide in your casement window hinge broke. Unfortunately, these are not available by themselves and so you will need a new hinge entirely. Check out our 36-013-10 and see if this can possibly work as a replacement.
