It is suitable for various types of doors, family doors, and shop doors. </p> <p> STRENGTHEN THE TENSION TO 1200G + BUFFER DAMPING: Compared with the old door closer, 1, we upgraded its tension. Now we can close heavier doors. Of course, your door damping does not exceed 1200g. The door is no longer closed suddenly and quickly; 2. We added a buffer damper to make it slower, more comfortable, and more friendly to the door; 3. We lengthened the length of the door closer, which is now 1.5m (4.9ft). </p> <p> EASY INSTALLATION, 2 INSTALLATION MODES: 1. Glue fixation (faster and more convenient); 2. Screw drilling (more firm). </p> <p> DURABLE: Door closer residential, we have tested the fatigue strength for tens of thousands of times and can be used for a long time. </p> <p> 50,000 Tests and 1200G Pull: The high-quality steel wire rope has passed 50,000 times of tensile tests and rebound tests, with 1200G super tensile force, suitable for commercial doors with strong closing force, anti-theft doors, and residential doors. </p>
