The weight plate center holes are machine-bored to ensure proper fit of all 2" or 50 mm diameter sleeve Olympic bars. Plus, the machining process creates a smoother surface, enabling easier plate loading and unloading.
The plate edges are precision-milled to create a more rounded shape versus cheaper entry-level plates on the market. Raised silver lettering displays the plate weight in pounds and kilos, plus, shows the famous "Standard" name.
The Troy BOSS Olympic Set comes with 7 ft. chrome bar that makes up the other 45 lbs. in the set. It is designed primarily for home use, offering a 500 lb. static capacity and spring collars to hold it all in place.
