Casement window crank

Question

I am looking for window cranks for 4 windows. Attached are pictures of the current cranks. Please let me know any additional information you need to confirm availability. It says Truth on the arm.

This looks like either a 39-253LB & 39-253RB or the 39-438B & 39-439B. The key difference between these two sets of operators are the appendages at the end of the straight arms. The 39-253LB uses a square track slider sold separately, our 39-529, while the 39-438B uses a rectangular black slider that comes built-in to the straight arm. This slight difference effects window compatibility, so be sure to confirm what you have.
