ZKC has supplied their weightlifting equipment to the 2008 Beijing Olympics and also at the 2016 Rio Olympics. It is one of the five companies whose equipment is certified for use in International Weightlifting Federation sanctioned competition.
When looking for competition collars you can trust, they don’t come more trustworthy than the Zhangkong Competition Collars.
Weighing an exceptionally accurate 2.5kg and super reliable grip-to-bar, both the accuracy of the lift and the safety of the lift are prioritised. Heavily plated bars and downward pressure on these collars are not a problem, which has given them the International Weightlifting Federation approval.
