6, 10, 12 Or 20 Ladder? Buying The Right Ladder Size
Ladders are available
in different sizes and are usually available in 6, 10, 12, 20, 40 feet.
Buying the right size or length of a ladder is as important as
determining on other aspects of a ladder such as its
construction
material, purpose and manufacturer. Buying a ladder that is either too
short or too long is often a mistake made by homemaker which could
potentially be dangerous. As a general rule buy a ladder that has 7 to
11 feet more in length than the height of support point. For example if
the height to gutter or to support point is 13 to 17 feet, you should buy a
24 foot ladder.
