Product Overview
Stainless-Steel Plate-Fork Hammock / Swing Set Hangers – Model ZB4002
Turn any wooden beam, concrete ceiling or steel post into a 300 kgf-rated swing station in five minutes.
RICHWITS ZB4002 combines a laser-cut 316 stainless plate with a forged fork eye—CNC-shaped to accept carabiners, hammock chains or swing straps without chafe.
8.5 mm thick backbone—20 % heavier than DIN 5299—handles dynamic loads and kids’ jump force with zero flex.
The 45 mm offset fork keeps ropes clear of walls, while the radiused edges protect webbing and bare feet.
