Truth Window Crank

A handy person from Marysville, Ohio says:
I need to replace two window cranks that say they are Entry Gard by Truth 20755. Both arms seem to move in the same direction. Could you please give me some assistants on what I might need.

Start by comparing the dimensions of your operator to our 39-155 and see if this will work for you.

Thank you this is perfect . Is there a different number for one that opens to the right??

That would be our 39-156. I hope this helps!!
