【Durable Cold-Rolled Steel Material】The hydraulic gas spring is made of durable, high-quality cold-rolled steel, offering maximum resistance to corrosion and wear. This ensures reliable and continuous support for your cabinet or furniture for a long time. 【High Load Capacity】The cabinet gas spring is easily installed on either the left or right side of the cabinet or furniture. Its robust construction and 20 kg (200 N) load capacity make it compatible with most cabinets and storage units. 【Excellent Damping】The gas spring gently lifts the cabinet door and closes it smoothly. It doesn't slam shut, preventing finger injuries and reducing noise from the lid hitting the door. Maximum lid dimensions for gas spring installation: 130 cm (50 inches) long and 65 cm (25 inches) wide. Ensure the interior depth is at least 23 cm for optimal stability. Multiple uses: This kit includes 2 lid-holding hinges. They allow the door to lift and stay open until you close it. Suitable for cupboards, wooden chests, toolboxes, windows, folding beds, wardrobes, tool boxes, etc.
