Highland 0700500 8" Aluminum Ramp Kit

Okay, I ordered this ramp kit based on the great comments.
You can use 2"X10" boards I did use 2"X8", but 2"X10" will work fine.
However you will have 1" over hang on both sides of the brackets if you use 10".
Now if you have a concern about the wood being slippery if they get wet, two suggestions read the instruction that recommend a kit that is an anti-skip plate type of unit. I used paint and added a little sand to it, it's an old painter's trick (yes I'm old)... or just use spray paint undercoating or truck bed lining paint. I will have many years of use from these ramps.

These are excellent. Kit has both top an bottom to attach to a 2x8 or 2x10. Length is dependent on height because the angle of the top will come out flat if you use the correct length. Lays right on the tailgate of my pickup. Self adhesive protective pads will protect the paint. Very strong. It's just what I needed.

Great product! Easy to assemble! The only addition to this product that I would suggest would be buying some traction tape for the boards. When the wood gets wet it is slippery.
