I'm installing a few new doors, and bought slab doors to save some money. I have a jig for boring the door knob holes, but I'm not sure where on the door to put the hole. Is there a standard height for door knobs?
According to the International Building Code, door knobs should be between 34" - 48" above the finished floor.
