Confezione da 2 cerniere per coperchio e ribalta in lega di zinco argentata.

Made of high-quality zinc alloy, rust-resistant and durable. Using the included Allen wrench, these seat rails can be adjusted by rotating the screw in the center of the arm to accommodate different weights, thus setting the appropriate friction to prevent the lid from suddenly falling when closing. Each rail is adjustable left and right; the door opening angle is adjustable: 75°, 90°, or 110°. Maximum load capacity: 18 kg/2 pieces. Suitable for situations requiring gentle closing of the door or lid, such as those where installation screws and an Allen wrench are included for easy installation. The door can be secured in any open position or allowed to slide down gently, avoiding a violent fall that could injure fingers. Tension can be easily adjusted by rotating the screw in the center of the arm to set the appropriate friction, preventing the toilet seat from slamming shut. Installation accessories included. Easy installation. Hydraulic damping system and springs not included.
