At first glance, this looks like any other fiberglass stepladder, until you see the angled corners and notch in the top. The shape of the top lets you lean the folded ladder into inside corners or onto outside corners and posts—without fear of sliding. A latch keeps the legs closed while the ladder is being leaned; in the open position, it works like a regular step ladder. The aluminum steps are heavily braced, and the top has rubber bumpers and is shaped to hold tools and fasteners. These Type 1A (300-lb. rating) ladders are available in 4- to 12-foot sizes. Price: $100 to $325 /
