Types of Ladders & How to Choose the Right One
From stepladders to extension ladders, understanding the different types of ladders helps you work safer, smarter, and at the right height for any task.
Choosing the right ladder starts with understanding the types of ladders available and matching them to your project’s requirements.
Types of Ladders
Step Ladders
The most popular and versatile style, stepladders are ideal for medium- to low-height tasks. Many come with pail shelves or tops to hold tools, paint, or supplies while you work.
Mechanics Ladders
Designed to allow two people to work side-by-side, mechanics ladders make it easier to complete tasks that would be difficult for a single person.
Platform Ladders
Platform ladders combine the features of a stepladder with the stability of a warehouse ladder. A non-pinch platform provides a spacious standing area, making it perfect for tasks that require long periods of standing.
Extension Ladders
The go-to choice for reaching high elevations, extension ladders are adjustable, making them one of the most versatile long ladders available. They come in a variety of sizes for both residential and industrial use.
