Construction Details of a preassembled stair

The Cooper Difference is in the details.

Pocket Screw from Riser into Tread - See Top Circle above - Secures the tread to the riser to ensure a tight connection without relying on glue.
Tongue and Groove - See Bottom Circle above - Creates a sure fit for the riser and tread and virtually eliminates squeaks.
