I bought this last to move a Daytona 600 in a closed 6x10 trailer. I laid 2 e-rails on the floor and attached the e-rails holding the 2x4. I then attached the pieces of wood to the E-rail clamps and brace. Used straps front and back. Driven 85 km without problems. The deck is heavy and durable. Great for the mid-$30 range. I'll unbolt it and put it in the garage to keep the bike there. Good value sent quickly. The wheel chock comes with 4 long bolts with 4 thick rubber washers and 4 nuts. would recommend. I paid for this product, it wasn't free.
