LEVELOK LADDER LEG LEVELER, $99.99 Aluminum & Fiberglass Extension Ladders
This turns out to be a sturdy, dependable, and easy to use Ladder Leveler for your extension ladders. I really liked that when you install it, you don't have to cut or remove anything from your existing ladder. Operation is a snap with only your foot, and its easy to install. I highly recommend this product.
