Casement crank

A contractor from Minnesota says:
The lower control arm handle is very loose and mechanism is loose. Would like to replace lower parts to have a nice smooth opening experience. No idea of brand. Any ideas?

I believe you have Ashland hardware. Unfortunately, I don't believe these are still available. Our suppliers do not carry them anymore and I don't know who still might. You could consider something like our 39-013 as a possible substitute, along with our 39-505 track and then a hinge like the 36-013-18, 36-004-10, or 36-004-14, but I cannot guarantee if these will work for you. I'm sorry that we can't give a more confident recommendation.
