Don t include the carpet backing just the soft fibers from the backing up.
The strip is supported on both sides by the lips and held in place with nails.
Large format tiles such as 18 by 18 inch and 24 by 24 inch can.
The pile height measurement is not usually shown on the carpet sample however all you need is a tape measure.
Wood for example has a very different finish height than ceramic tile.
The leg of the t doesn t touch the floor.
T molding transition strips have two lips to cover the edges of both surfaces when flooring products differ no more than about 3 8 inch in height.
