Sturdy Door Closer: The spring-loaded door closer can be used on doors up to 69 kg. Ideal for indoor gardens, outdoor doors, gates, or garden shed doors. Easy-to-adjust spring tension. 【Automatic Closing】- Automatic closing and locking ensures peace and security. During breaks, you don't have to worry about escaping from the house or your dogs and cats running around your room. High Quality: The lightweight door closer is made of stainless steel, which is antioxidant, corrosion-resistant, rustproof, stable, abrasion-resistant, weather-resistant, quiet, and safe. Adjustable: This hands-free spring-loaded door closer has an adjustable closing speed. It can be used on both left- and right-handed swing doors. 【Installation Notes】 – To avoid over-tensioning, adjust closer by a quarter turn at a time and test the door after each adjustment. Excessive tension can cause the spring to buckle. If you wish to add extra lubricant to the unit, carefully disassemble it after relieving the tension and apply white lithium grease directly to the springs.
