Installation Tips

• A 12” - 16” gap (or less) between support framing under the planks is recommended. Over 16” is not recommended.

• When cutting each plank to length, leave a ½” to ¾” gap next to the sidewall at each side of the trailer to facilitate the cleanout of manure and mud under the planks.

• You can vary the gap between planks. Distances vary from 0” to 1” but completely up to you and your state regulations. 

• A minimum of two 5/16 - 18 x 2 ½” (diameter, thread count, length) self-tapping trailer flooring screws are recommended at each end of each plank. Additional screws along the plank every 24” are also recommended to help control movement. (Note: type of screws pictured in the photo below are for alignment demonstration only)

• Screw alignment is very important. You must catch the full height of the plank with the screw. Use the groove lines (see photo below) on the upper sides of the planks as a placement guide to drill pilot holes through the plank and framing before driving the screws.

  • IMPORTANT: The screws fastening the plank down MUST pass through one of the legs on the underside of the plank. If not secured through the bottom legs (see photo below) the screw head may pull through the plank.

• You may have odd 4” or 6” spaces left between a full plank and the next steel plate. You can rip boards lengthwise with any standard woodworking tool to get full coverage between plates.

  •  IMPORTANT: If you rip a plank to fit an odd space, make sure you have at least two underside/bottom legs remaining. (see photo below)

  • You may consider ordering an additional plank to ensure you can complete the installation.

• If you have any small bits of plank left over at the end of the project, they make great stepping stones.
