The J-cup is the interface between a few hundred pounds of steel and your shoulders. It should be dead solid and it should not damage the bar sitting in it.\u003c\/p\u003e\n\u003cp\u003eThe sandwich construction is what makes these different from a standard hook. Instead of hanging off one face of the upright, the cup wraps around it, which distributes the load and eliminates the rocking that makes a cheap cup feel unstable. Under 1,000 lb of capacity, the cup does not move, so your bar height is identical set after set.\u003c\/p\u003e\n\u003cp\u003eInside, injection molded plastic takes the contact instead of bare steel. Your knurling stays sharp, your bar finish stays intact, and re-racking is quieter. The open sandwich profile also gives you a wider target coming back in, which is the difference between a clean re-rack and a scramble at the end of a hard set.\u003c\/p\u003e\n\u003cp\u003eFinished in black powder coat and sized for 3\" x 3\" uprights, these are a straightforward upgrade for any PRx rack owner who wants their bar to feel planted.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"fs-section\"\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable class=\"fs-ratio-table\"\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e10.5\" x 3.5\" x 10\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight Capacity\u003c\/td\u003e\n\u003ctd\u003e1,000 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eBlack powder coat\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBarbell Protection\u003c\/td\u003e\n\u003ctd\u003eInjection molded plastic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUpright Size\u003c\/td\u003e\n\u003ctd\u003e3\" x 3\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"fs-cta\"\u003e\n\u003cp style=\"margin:0 0 8px;font-size:18px;\"\u003e\u003cstrong\u003eReady to Build Your Dream Gym?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"margin:0;font-size:15px;\"\u003eOur fitness experts are here to help you design the perfect setup for your space and goals. \u003ca href=\"https:\/\/fitnesssupply.com\/pages\/consultation-request\"\u003eSchedule your free consultation today\u003c\/a\u003e and let us bring your vision to life.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"PRx Performance","offers":[{"title":"Default Title","offer_id":62856948449439,"sku":"PX481","price":139.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0631\/0871\/0559\/files\/3D9A6360_7e4ef0a6-bfb8-4010-bdbe-efe0fcccb6a4.jpg?v=1788211131","url":"https:\/\/fitnesssupply.com\/ja\/products\/prx-3x3-sandwich-j-cups","provider":"Fitness Supply","version":"1.0","type":"link"}
