Congrats! This is the folding rack for you.Its 1,000-pound capacity outlasts heavy squats, handles big bench presses and withstands chin-ups with 8 kids hanging onto your waist — just bolt it securely before you go trying for that new chin-up PR.The uprights measure true 3″ x 3″ which is EXACTLY 76.2mm x 76.2mm, instead of the typical 75mm x 75mm uprights of other brands’ imported racks. By matching the same tubing specs as many of our American competitors, you can mix and match attachments freely without needing to stick to one brand — hello, open ecosystem! You can even side-mount your 5/8″ attachments (as long as they’re destined for true 3″ x 3″ tubing) using the side keyhole slots; perfect if you prefer the more economical Hydra rack attachments, now that’s a fairy tale come true!Built with modular components, so you can expand later into a larger Manticore rack to accommodate a new home gym space or team workouts with your swolemate.Compatible with Manticore rack attachments.1x Set of Wall Mount Hinges (set of 4)1x Set of 8\" Folding Rack Wall Connector (set of 4)2x Pairs of 84\" Uprights2x Pairs of 30\" Crossmembers1x Adjustable Straight Pull Up Bar w/ lock pins1x Pair of Sandwich J-Cups 1x Logo Tag\nIMPORTANT: The Manticore series of power racks are TRUE 3″ x 3″ tubing with 1-inch holes, so only Manticore attachments & non-B.o.S. attachments made precisely for 76.2mm x 76.2mm uprights with 1-inch holes will fit.","images":["https://cdn.shopify.com/s/files/1/0654/3346/9125/files/FOL-MTC-PREBLT-01.jpg?v=1777374519","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/FOL-MTC-PREBLT-02.jpg?v=1777374519","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/FOL-MTC-PREBLT-03.jpg?v=1777374519","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/FOL-MTC-PREBLT-04.jpg?v=1777374519","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/FOL-MTC-PREBLT-05.jpg?v=1777374519"],"price":1269.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:45.943Z"},"share_url":"https://firestarter.network/l/lst_FJbfPD4P","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
