What does center-to-center hole spacing mean for handlesets?
When ordering a handleset, the center-to-center hole spacing is a measurement you need to determine. Two holes (typically 1-1/8″ in diameter) are typically bored into a door to accommodate a handleset (either a single or double cylinder handleset). The measurement is made between the center of one hole to the center of the other hole. The most common center-to-center measurement is 5-1/2″; however, it can be different, and you need to make sure before you order.
