How to Cut Inside Corners of Chair Rail Trim How to Cut Inside Corners of Chair Rail Trim

What You'll Need
Chair rail
Miter box
Circular saw

You may install chair rail trim to protect your walls from getting damaged due by the backs of chairs or simply to transform the look of bare walls in a room. The cost of rails varies by the type of material from which they are made as well as their size and shape. You may find trim made of genuine wood or some other synthetic material, but also in a variety of different widths and designs.

Step 1: Cutting the Inner Corner of Rail

Insert the rail into the miter box with its front face touching the back of the miter box.

Step 2: Mitering the Rail at 45 Degrees

Hold the molding in your hand, and cut the end at a 45-degree angle with the coping saw. You can also use a miter saw for cutting the rails. Once you have cut one corner end of the rail, cut the corner as well.

Step 3: Cutting the Other End of Rail

Measure and mark the place where you will cut, and position the rail with its plane face touching the back of the miter box. Cut at the marked position at 45 degrees. Now both the inner corners of the rail are cut.

Step 4: Cutting the Mating Piece

Repeat the above steps to cut the other mating piece of railing that will be fixed with the first piece in the corner.
