This wedge-shaped platform safely balances a ladder on sloped ground.
When setting up ladders on uneven ground, I used to go searching for a scrap of wood to prop up one leg of the ladder. But eventually I made the simple rig shown in the drawing. It’s a wedge-shaped platform made from a piece of 3/4-in. plywood screwed to two pieces of 2x lumber diagonally ripped in half. On top of the plywood is a 1×1 wooden strip that prevents the ladder’s feet from sliding. The strip is centered on the plywood so the wedge can be used with the slope in either direction. At 16 in. by 24 in., the plywood is sized to accept most ladders and it works with most slopes.
