From people who brought you the Tri-Vise comes the Lumber Lok, which securely supports most conventional lumber sizes above the ground so you can cut, notch, drill, or perform other operations.
Made in the USA by Tri-Vise Industries, the steel Lumber Lok weighs 4.3 lbs. They powder coat it to keep it from corroding and print a 12″ ruler on one edge for convenience. The tool has openings for 1x4s, 1x6s, 2×2, 2x4s, 2x6s, 2x8s, 2x10s, 2x12s, and 4x8s. You can pick up the Lumber Lok for $30 shipped.
Although I have no experience with their products, I do suggest Tri-Vise Industries fire the person in charge of building an all-flash site that automatically plays sound effects when you open it. It was an annoying practice eight years ago, and is no less so today. Also, it’s just dense not to realize you’re thumbing your nose at mobile users.
