A difficult part of any installation process is lifting the objects to be installed. This applies even more to heavy objects. That's why a team of individuals typically builds heavy objects. But what if you need to install something, say a door or a cabinet, and you don't have a team to help you? This makes for a sticky situation. However, DIY installation doesn't have to be so complicated when you have a labor-saving jack to help you lift things. The labor-saving arm has a lifting capacity of 120 kg (330 lb)! This makes lifting heavy objects a breeze with this tool.
