Selecting the right ladder

Extension ladders require a surface, such as a wall or a roof line, for support. They’re usually available in larger sizes than step ladders, making them a good choice for outdoor projects, like cleaning gutters or painting the outside of a home. Be sure you know your average reach height when shopping for your ladder. Using a ladder that’s too short or tall can hamper the safety and efficiency of your work.

Ladders Buying Guide

Common ladder materials are Aluminum and Fiberglass. Aluminum ladders are corrosion-resistant, strong and lightweight, making them a durable choice that's easy to maneuver and carry. Aluminum ladders also conduct electricity, however, so don’t use them when working on electrical projects or near electrical lines. Fiberglass ladders are strong and durable. When clean and dry, they don’t conduct electricity and are the right choice for electrical projects and work near electrical lines.

Product arrived late and damaged

Would Not Recommend

I had to wait 3 weeks for the item to arrive at the store and then I had to wait 15 minutes for the attendant to bring out the item, then when I got home and unwrapped the plastic, it was damaged.

Just started coming apart

Would Not Recommend

I have bought many of these ladders though the years, my last purchase of 2 of them, one of them just started coming apart one rung at a time for no reason! 1 rung then the next then rung, and being only a couple of months old would expect better quality!

It's a ladder.

Would Recommend

It's a ladder, what can I say. Seems to work fine. If you want a quick grab and don't want to carry or unfold your step ladder this is the one. Took a month to arrive to my store after ordering. I paid $109 and it went on sale for $89 while in transit!
