{"type":"firestarter.listing","listing":{"id":"lst_55VijvW8","product_name":"Gray Mighty Grip Olympic Weight Plates","category":"Weight Plate","description":"The Mighty Grip Olympic weight plates feature a beautiful, ergonomic design with an ultra-durable hammertone powder coat for superior toughness and resistance to chipping.The precision grip handles make loading plates onto the bar and re-racking plates a breeze, and they're large enough for even huge hands.The comfort grip also allows the plates themselves to be used for exercises like steering wheels and farmers' carries.These plates are excellent quality iron plates made in a factory with over 40 years of casting experience. Because they are only cast and not machined, some minor blemishes and a +/-3% weight tolerance / 51mm hole are standard in the plates.If you're looking for a precision fit and machined-to-perfection plate, be sure to check out our Machined Iron Plates.IMPORTANT: Because they're cast iron instead of machined, some minor blemishes, +/-3% weight tolerance &amp; 51mm hole are standard for them.","images":["https://cdn.shopify.com/s/files/1/0654/3346/9125/files/V-MGP-PRNT-carousel-primary.jpg?v=1764592489","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/V-MGP-PRNT-carousel-8-carousel-primary.jpg?v=1764592489","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/V-MGP-PRNT-carousel-6-carousel-primary.jpg?v=1764592489","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/V-MGP-PRNT-carousel-5-carousel-primary.jpg?v=1764592489","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/V-MGP-PRNT-carousel-7-carousel-primary.jpg?v=1764592489","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/V-MGP-PRNT-carousel-2.jpg?v=1764592489","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/V-MGP-PRNT-carousel-5.jpg?v=1764592489","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/V-MGP-PRNT-carousel-6.jpg?v=1764592489","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/V-MGP-PRNT-carousel-4.jpg?v=1764592489","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/V-MGP1-carousel-primary.jpg?v=1764592489","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/V-MGP2-carousel-primary.jpg?v=1764592489","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/V-MGP5-carousel-primary.jpg?v=1764592489","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/V-MGP10-carousel-primary.jpg?v=1764592489","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/V-MGP15-carousel-primary.jpg?v=1764592489","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/V-MGP25-carousel-primary.jpg?v=1764592489","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/V-MGP35-PAIR-carousel-primary.jpg?v=1764592489","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/V-MGP45-PAIR-carousel-primary.jpg?v=1764592489"],"price":22.09,"currency":"USD","in_stock":true,"inventory_qty":69993,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:45.725Z"},"share_url":"https://firestarter.network/l/lst_55VijvW8","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
