Finally, multi-purpose ladders are designed to incorporate a number of the above designs. This typically means they can extend, or fold in to smaller size, as well as feature numerous steps and rungs. For this reason they may also be called multi-position ladders, as the customisable features allow you to set them up in the desired position and height you wish.
Multi-positional ladders are useful in more unique situations, such as on uneven surfaces. The two sides can be set at different heights, ensuring the ladder is still balanced. This makes them great on stairs and steps, for instance, where other ladders might lack these features.
While this is highly advantageous, these ladders are often heavier and bulkier as a result. While modern designs use lightweight material, such as aluminium, to offset this, it is always something worth keeping in mind.
As you can see, two ladders are ever seldom alike. While there are many ladders designed for a variety of uses, the specialist ladders offer extra support in some key areas. Knowing what you need will easily help you narrow down your options and find the right ladder for you!
