The 20-yard roll-off container is widely considered the “workhorse” of the waste industry due to its ideal balance of high capacity and a manageable footprint. It is the most requested size for both residential and commercial projects, offering enough volume to handle substantial debris without requiring the excessive space of a 30 yard roll off container. AJ Waste Systems offers two types of 20 Yard Container. 20 Yard “Hook” Container, has the footprint of one parking space and is about 6.5 feet tall, and the 20 Yard Roll Off as displayed.
