Pre-Drilled Stair Posts for Stair Applications

The pre-drilled stair posts measure at 2-3/8". Because of many variables in stairs, these posts do not come with base plates attached. This way you can place, adjust and mount the posts where needed. Stair post holes are slotted and drilled at 3-3/16"OC and offset to allow cables to pass through at the angle of the stair. Their length of 46" allows the posts to be cut at appropriate height.
