https://www.ironcompany.com/valorathleticssquatracksweightbenchesspeedbagplatformsandmore.aspx – Sometimes fitness equipment manufacturer Valor Fitness receives e-mails or phone calls regarding how certain units are assembled. One of those questions or concerns is “why is the unit so wobbly once I have it all together”? There could be numerous reasons but the one that seems to surface the most is that some customers do not understand what “self-locking nuts” are. So, Valor put together a little video just on the design, purpose, and “how to” assembly regarding the self-locking nut. Hope this answers some questions!
