Buying Guide: Best Picture Frame Molding Kit for Stairs
Use these points to choose the best picture frame molding kit for stairs.
Find the stair angle
Hold a bevel gauge against the stringer or handrail to find the angle, often 30 to 38 degrees.
Parallelogram frames
Stair frames have two angled sides that match the slope and two plumb sides.
Split the angle
Each corner miter is half the corner angle. Cut test pieces from scrap first.
Long lengths help
Long pieces reduce joints on the sloped top and bottom rails.
Follow the stringer
Keep the bottom rail parallel to the stair stringer or baseboard.
Use a miter saw
Angled corners are hard with a hand miter box; a power miter saw helps.
Staircase Molding Tips
Frames that follow the slope.
- Measure the stair angle with a bevel gauge.
- Make a cardboard template first.
- Cut test miters from scrap.
- Keep rails parallel to the stringer.
