Also, as per our customer’s feedback, we have made some changes to make our SLIDEback version a better closing speed… If there is a sliding door in your home, no matter it is glass, metal, or wooden sliding door, we will recommend you to install our SLIDEback on it since it is easy to install and do not have to purchase the whole set of a sliding system, just a SLIDEback can make your sliding door close automatically, like an automatic door. What’s more, it does not need electricity, so you do not have to worry about the electricity bill every month, it is very economical.

If you are not sure which series or power force is more suitable for your sliding door, please feel free to contact us.

There are a series of specific cycle testing, prototyping, quality checking, and assembling tools in our factory, please refer to the following photos,
