Simple to use: install the small round part on the door and the longer part on the wall where you want to keep the door open. Note: if the longer part is installed on the floor, the hydraulic buffer will not function. Package includes: 2 magnetic door stops, 10 screws; magnetic door stop can enhance daily convenience.
