How To Choose Your Ladder

 

To make a safe ladder choice, duty rating, ladder length, and the material from which the ladder is constructed are the most important elements.

Duty Rating:

Most ladders are designed to support one person plus the materials and tools for the job. To help you make a safe choice, the American National Standards Institute (ANSI) has developed tests that determine the duty rating, type, and maximum working load (which includes tools, planks and materials as well as the user) for every ladder. Every ladder has a label that provides the duty rating information you need. The labels are color coded based on the duty ratings (see below). The following chart will be useful when making your choice:

Ladder Length:
