The end cap is a right-angle shaped piece, designed to end a floor by covering the top and side of its edge. End caps are used to border off where a floor ends, such as at a doorway or when the height difference between two types of flooring is too extreme for a reducer.
T-molding is used when transitioning between two floors that are of equal height or within ⅛” in height of each other. T-molding helps streamline the flow of your home when these two floors meet.
Stair nosing is the horizontal, protruding edge of a stair where most foot traffic occurs. This molding would be used to finish the step, in addition to another plank of flooring, and cannot be used with a stair tread.
Reducer moldings are used when two floors of slightly different thicknesses come together, such as a laminate floor and a wood, vinyl, ceramic or low-pile carpet floor.
Quarter Rounds are used with baseboards to cover gaps where the it and the floor meet.
