The hammock hanging kit features a flat top and a lock nut design to maximize strength. Suitable for various swings, hammocks, and punching bags with a working load not exceeding 350 kg. Special design: Integrated screw and washer design with wear-resistant washers on both sides to reduce direct friction, provide high wear resistance, and ensure quiet operation. The bracket with a lock nut can rotate 180 degrees vertically for better weight support. The hanging hook bracket rotates 360 degrees freely and includes a spring-loaded snap hook to securely lock the hook in place and prevent accidental disengagement.
