heyous Detachable Oblique Stainless Steel V-Type Groove Sliding Wheel Roller Track Rail Fixed Pulley, Silver Tone

If you need a pulley this one is top notch

This pully seems ligit but BEWARE they fail to put the weight capacity of this on the description. I would say that a pretty important piece of info needed...

Good quality pulley for use with winch cable to raise and lower my two hundred pound tailgate on my flatbed truck. Originally tailgate had a semi twisted rod inside the hinge, but it broke.
