• If you ordered a stair that has center balusters, they are installed after the handrail and wooden treads are installed. A combination wood screw / thread bolt is supplied. Thread the wood screw portion of the combination screw, into the pre-drilled hole in the wood tread.

• Tap a tube connector into the end of the baluster and thread the baluster onto the wood tread. Connect the baluster to the handrail as before.
