This spring-loaded foot-operated doorstop is the most convenient doorstop available. It's sturdy and durable, with excellent grip, allowing for easy pressing and releasing even barefoot. Suitable for various door gaps. This doorstop requires no bending over… simply press the piston to lock it in place, and press the handle again to release it, and the doorstop will spring up. Just carefully place it correctly on the door, ensuring it doesn't hit the door frame when closing, and adjust it to the appropriate height so the rubber feet make sufficient pressure on the ground. The built-in foot-operated telescopic spring makes opening and closing doors easy and avoids squeaking noises. The pedal is made of soft rubber that stops the door upon contact with the ground, and the soft rubber material also protects your precious carpets, floors, and tiles. This heavy-duty semi-automatic doorstop features a spring-loaded plunger and high-quality non-slip rubber feet, providing optimal grip on most surfaces. The rubber feet protect your precious carpets, floors, and tiles, so you don't have to worry about scratching your floors. Note: May not work well on smooth wooden floors., Manufacturer: Zxarunas us
