What is the main difference between an extension ladder and a step ladder?

An extension ladder is not self-supporting; it must be leaned against a surface. A step ladder has an A-frame design and is self-supporting.

How do I safely set up an extension ladder?

Use the '4-to-1 rule': for every 4 feet of height, the ladder base should be 1 foot away from the wall. Ensure both feet are on firm, level ground and the locks are fully engaged.

Can 'extension ladder' be used metaphorically?

Yes, though it's less common than 'ladder' alone. It can metaphorically emphasize adjustable or incremental progress towards a goal.

Is 'extendable ladder' the same as 'extension ladder'?

Essentially yes, but 'extension ladder' is the far more standard and widely recognized term in technical, commercial, and everyday use.
