Different people, projects and tasks require ladders of varying styles, sizes, grades and materials. Style, size, duty rating and material are the four key elements to understand when choosing the right ladder for the job.

Style

When working indoors, a stepstool, stepladder, platform or multi-purpose ladder is usually recommended when you need a reach of two to eight feet. Outside, a taller stepladder, multi-purpose or extension ladder is often more appropriate for jobs requiring a reach of thirteen feet or more. Different styles of ladders are designed to keep the user safe and productive when climbing.

Size

Choosing the right size or length is just as important as the ladder style. One of the most common and potentially dangerous ladder selection mistakes is purchasing a ladder that is either too short or too long.

Choose the Right Extension Ladder

Material

We suggest that if you buy only one ladder, fiberglass should be your choice. Different ladder materials offer characteristics that are best for certain applications, and one kind of material may be better suited to your work environment or work application.

• Fiberglass — Electrically non-conductive, great value, strong leading choice of professionals.

• Aluminum — Strong, lightweight, corrosion-resistant.

• Wood — Economical, electrically non-conductive when clean and dry.
