High-quality stainless steel: The ceiling bracket is made of high-quality 304 stainless steel, smooth, rust-proof and corrosion-resistant, firmly welded and durable, with high load-bearing capacity. The sealing protection inside the hooks reduces direct friction and increases the service life, ideal for indoor and outdoor use. Flexible and rotatable: The swivel bracket can be freely rotated 360 degrees and rotated 180 degrees forward and backward. This makes the hook more flexible, vibrates less and can be used more widely. Easy to install: With two pre-drilled holes for screwing onto wooden beams or concrete. High load-bearing capacity: This heavy commercial swivel hanger can safely support 450 kg thanks to high-quality welding technology. Attention: This is only the load capacity of the hook. When using it, you should also consider the load-bearing capacity of the supporting object.
