Choose a step ladder for when you need a little extra height for the job. Step ladders offer a stable base to help you reach an extra couple feet. There are a few main things to keep in mind when choosing a step ladder. The first is that you'll want to choose a step ladder that is just the right height. If you choose one that is too high, you'll be putting strain on your back and neck. If you choose one that is too short, you will have to extend yourself, which can lead to potentially dangerous falls.
You should also consider what material you want your step ladder to be. Although all materials are durable, some are better for specific tasks than others. Wooden ladders conduct the least amount of electricity, so they are most effective for completing electrical jobs. That said, they don't last as long as aluminum ladders so for heavy duty jobs, you may want to go with an aluminum or steel step ladder.
