The Quarter Round molding is used to hide the expansion gap left during installation. The Tee molding is used as a threshold in doorways or as a transition strip where the bamboo flooring meets tile or carpet of similar height. The Reducer molding is used as a transition from the height of the sub-floor to the height of the bamboo. The Stair nose molding is used to cover the front edge of a stair tread or step. If used on a stair, flooring is installed behind the Starinose to cover the horizontal part (the tread) of the stair. The Stair tread molding is a one-piece molding used to entirely cover the structural stair tread.
