The Ladder Lock is a hand tool used to help secure extension ladders to a variety of surfaces. It helps prevent lateral movement when stepping on or off a ladder, as well as helping prevent property damage from the ladder sliding or blowing off the top. Saves time, money and effort in securing your extension ladder. Takes the guesswork out of what you can securely tie onto and installs in seconds. Studies show that the Ladder Lock is a great tool being used by many contractors to help achieve higher safety in the workplace. The working parts are constructed of steel with a strong spring for holding power. The spring is only part of the holding. The Ladder Lock is designed to work by binding itself against the extension ladder during lateral movement. This binding is encouraged by an over-sized washer that causes the Ladder Lock to bed at a predetermined angle. Some of our contractors tell us one Ladder Lock is enough, although we strongly advise using two. This is good especially for wall cap and drip edge connections.
