Introducing Deckorator's new square ESTATE BALUSTERS.  These 3/4" square aluminum balusters mount between the cross rails, just like the 3/4" round Classic Balusters.  No drilling required with the square Estate Baluster Connectors.  Simply screw down the connectors and the balusters fit snugly inside.  For stair applications, add the Stair Adapter to the bottom of the Baluster Connector.
