What is a Triple Extension Ladder? Your Guide

February 25, 2025 | Nate Cord

Extension ladders are ladders made up of two or more sections that fit together and can be adjusted in length. A triple extension ladder takes this concept even further, enabling even greater height without sacrificing portability.

So, what is a triple extension ladder and how does it differ to the other types of extension ladders? To put it simply, a triple extension ladder consists of three sliding sections (hence the ‘triple’ in the name), allowing it to extend to significant heights while remaining compact when not in use and folded up.

The other popular type of extension ladder is a double extension ladder, which, you guessed it, has only two sections. When comparing the two, a double-extension ladder has to be extended just the once, making it slightly easier to use than a triple-extension ladder. However, a triple-extension ladder can be closed down smaller, making it easier to store, manoeuvre and transport. A triple extension ladder therefore provides you with extra height without requiring as much storage space when collapsed.

Are Triple Extension Ladders Safe?

You’ll be pleased to know that, yes, triple extension ladders are absolutely safe when they’re used correctly. Ultimately, a triple extension ladder, as with any ladder used when working at heights, is just as safe as the person using it.

Tips for How to Use a Triple Extension Ladder​ Safely

As triple extension ladders extend to significant heights higher than any other form of extension ladder, stability is a concern if the ladder is not placed on a level surface or properly secured.

To ensure you use a triple extension ladder safely, users should always adhere to safe best practices/guidelines, such as maintaining a 3-point contact (two hands and one foot or two feet and one hand), extending the ladder at the correct angle (4:1 ratio), and ensuring the ladder is fully locked in place before mounting and climbing. You might also want to use stabilisers to reduce the risk of tipping even more.
