Ferme-porte, amortisseur de porte à ressort réglable en acier inoxydable, noir

【High-Quality Stainless Steel】Made of high-quality stainless steel, thickened throughout for strong load-bearing capacity, corrosion resistance, and durability. The bracket is made of chrome-plated plastic to prevent metal-to-metal friction noise (do not overtighten during installation). 【Reduces Closing Force】Automatic door closer. Helps reduce closing force, protecting the door from damage. Adjustable tension and screw-adjustable closing speed create a quiet and comfortable environment. 【How to Adjust Force】To adjust the force, first pull out the pin, then use an Allen wrench to rotate the end, and finally insert the pin into the corresponding hole. The door closer reduces the force required to close the door. Fully automatic closing with adjustable speed ensures safe closure. 【Wide Range of Applications】This adjustable door closer is suitable for various types of central doors—left-opening, right-opening, wooden doors, residential and commercial doors, interior and exterior doors, and fire doors. The door and door frame must be flush, whether left-opening or right-opening. 【Easy Installation】This interior door closer is easy to install: simply place it between the door frame and the door and tighten. It is suitable for both left-opening and right-opening doors and can also be wall-mounted. Threaded connections are easy to install and remove, durable, quiet, and convenient to use, improving efficiency and ease of use.
