How to Build Snowboard Box Rails

How to Build Snowboard Box Rails
A rail in your backyard is an excellent way to keep in practice when you can't make it to the mountain. A box rail, which is a rail with a wider top surface, is excellent for beginners because of its stability. Building your own box rail may seem complicated, but with an afternoon, a bit of know-how and some simple supplies, you can make your very own box rail.


Difficulty: Moderately Easy

Assemble the Box Rail

Things You’ll Need:
  • 5 8-foot 2x4s
  • 1 4x4 at least 4 feet long
  • 3-inch screws
  • 3 5-inch, 1/2-inch diameter bolts
  • 5 7-inch, 1/2-inch diameter bolts
  • Saw
  • Tape measure
  • 3 pier blocks
  • Stain
  • Power screwdriver with 1/2-inch drill bit
Step 1
Cut the lumber. Cut the 4x4 into three 16-inch lengths. In one end of each, cut a notch 1.5 inches deep and 1.5 inches wide. Cut three 10-inch lengths of 2x4. In each, cut a 6-inch notch on the long side, 1.5 inches deep.
Step 2
Secure the vertical supports. Place a 4x4 in the metal "shoe" of each pier block, notch end up. Drill a 1/2 inch hole through the base of each 4x4 to match the hole in the shoe. Fasten the supports to the pier blocks using the 5-inch bolts.
Step 3
Place the horizontal supports. Place one of the 10-inch 2x4s in the center of each of the notches at the top of the 4x4s, with the 6-inch notch up. Secure it in place using the screws.
Step 4
Mark the 8-foot 2x4s in the center of the long side at intervals of 6 inches, 2 feet, 4 feet, 6 feet and 90 inches. Drill a hole through each mark using the 1/2-inch bit.
Step 5
Attach the 8-foot 2x4s together into a block, using the 7-inch bolts.
Step 6
Place the box rail onto the horizontal struts, securing it into the 6-inch notches. Affix it at the sides using the 3-inch screws.

Complete the Box Rail

Step 1
Stain the rail assembly. This will weather-proof it and ensure long life. Re-stain every year.
Step 2
Coat the rail with water and let it freeze overnight. This will both make it slicker and keep it from wearing, as you will be grinding on the ice, not the wood. Water the rail after every session.
Step 3
Pack the pier blocks in snow. This will increase the box rail's stability, as well as put some padding between you and the blocks.

Tips & Warnings

Always use protective gear when using power tools.
Do not use the rail without snow.
