This design improves safety and ease of use in powerlifting competitions and heavy weight training.\u003c\/p\u003e\n\n\u003ch4\u003e Roller J-Cup Rotation Structure\u003c\/h4\u003e\n\n\u003cp\u003e The built-in bronze bushing (bronze sliding bearing) provides extremely high durability and stable rotation from light to heavy weights. \u003cbr\u003eAfter comparing with many overseas products, it was confirmed that the roller J-cup with built-in metal bushing rotates smoothly even under heavy loads, and the roller J-cup of the MBC original rack was developed taking advantage of this feature.\u003c\/p\u003e\n\n\u003ch4\u003e Fixing mechanism for improved safety\u003c\/h4\u003e\n\n\u003cp\u003e Because the Roller J-Cup supports the weight at points, it will move left and right when adjusting the barbell position without a fixing mechanism. To solve this problem, the Roller J-Cup of the MBC original rack is equipped with a removable locking knob bolt.\u003cbr\u003e For safety, be sure to use the locking knob bolt when doing exercises that involve lateral movement, such as squats. For exercises such as bench presses, you can use the exercise without tightening the knob bolt. \u003c\/p\u003e\n\n\u003cp\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/www.mbcpower.live\/pic-labo\/limg\/MRRJC10.jpg\" alt=\"MRRJC10\"\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003c\/p\u003e\n\n\u003ch5\u003e specification\u003c\/h5\u003e\n\n\u003cp\u003e *Detailed specifications may be changed without notice.\u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003e\n\n \u003cstrong\u003eProduct weight\u003c\/strong\u003e : Approximately 8kg per pair\u003c\/li\u003e\n\n\u003cli\u003e \n\u003cstrong\u003eSize\u003c\/strong\u003e : Standard size\u003c\/li\u003e\n\n\u003cli\u003e\n\n \u003cstrong\u003ematerial\u003c\/strong\u003e :\n\u003cul\u003e\n\n\u003cli\u003e Body: Steel (black powder-coated finish)\u003c\/li\u003e\n\n\u003cli\u003e Roller: Resin with metal bearings\u003c\/li\u003e\n\n\u003cli\u003e Barbell protection: Ultra-high molecular weight polyethylene (UHMW) insert\u003c\/li\u003e\n\n\u003cli\u003e Frame protection: Ultra-High Molecular Weight Polyethylene (UHMW) insert\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n \u003cstrong\u003eCountry of Origin\u003c\/strong\u003e : China\u003c\/li\u003e\n\n\u003cli\u003e\n\n \u003cstrong\u003eothers\u003c\/strong\u003e :\n\u003cul\u003e\n\n\u003cli\u003e Sold in pairs\u003c\/li\u003e\n\n\u003cli\u003e Free Shipping\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\n\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003c\/p\u003e\n\n\u003ch5\u003e Notes\u003c\/h5\u003e\n\n\u003cul\u003e\n\n\u003cli\u003e Optional specifications are subject to change without notice.\u003c\/li\u003e\n\n\u003cli\u003e Due to their construction, the Squat Stand Standard 180cm and MBC Training Combo Rack may not be able to use the dip handle attachment or plate storage.\u003c\/li\u003e\n\n \u003cli\u003eMBC original rack accessories are not compatible with other racks such as ROGUE racks.
