Anderson Window Sash Balance

Question

I have attached a picture of the balance. The number on the part is C33 6P23 377. The visible glass size is 32 1/2 inches long by 15 7/8 high. The part is 6 1/8 long by 2 7/8 inches wide. It is a double hung window installed in the late 70's I would like to order 4 in case I would need to replace another later on.

Thanks for posting! I recommend our 24-637. This can replace Andersen balance boxes stamped with 6P23.
