In the past, door closer mechanisms were quite complicated, which made them difficult to assemble on your own. Usually a trained professional had to be called to assemble them on-site. As a result, you would have to pay the labour cost for on-site installation on top of the actual product price, which made it relatively expensive. The door closer developed by our company is light, compact and easy-to-assemble. Assembly is done by just tightening three screws, so it is perfect for DIY projects.
Function: 1. Door automatically closes once it is opened.
2. When door is opened over 90 degrees, the door will lock in place so you can move things through the doorway without it closing.
