{"type":"firestarter.listing","listing":{"id":"lst_sVp2fnjo","product_name":"Manticore Flat Foot Power Rack Builder (3\" x 3\", 1\" Holes)","category":"Power Rack","description":"The Flat Foot Power Rack is where classic design and rock-solid stability team up with a chalky fist bump of swoleship.Its 1,000-pound capacity outlasts heavy squats, handles big bench presses and withstands chin-ups with 8 kids hanging onto your waist. 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 with Manticore components or divide it into two smaller Manticore racks to accommodate a new home gym space or team workouts with your swolemate.Compatible with all Manticore rack attachments, like the hyper-versatile Manticore Lat Pulldown.IMPORTANT: 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/MANTICORE_FLAT_FOOT_POWER_RACK_BUILDER_3__X_3__1__HOLES_f38171e8-c5b1-41a3-820d-60db17943376.jpg?v=1782378806","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/MANTICORE_FLAT_FOOT_POWER_RACK_BUILDER_3__X_3__1__HOLES_-_02_ae15ae70-aab5-4440-92c3-94b41e8c2f57.jpg?v=1782378806","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/MANTICORE-FLATFOOT-carousel-primary_55fcfed2-2bfa-46a1-aa9a-d7f205dea116.jpg?v=1766759029","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/Manticore_20Flat_20Foot_20Gallery_203_948da0be-9c69-48ea-a297-ea54cb7631a5.jpg?v=1766759029","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/Manticore_20Flat_20Foot_20Gallery_201_e4b5c4b4-b084-4b0b-a6cb-f48a7f676aa5.jpg?v=1766759029","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/Manticore_20Flat_20Foot_20Gallery_202_cbbcde6c-5345-49dd-9358-77627122344f.jpg?v=1766759029","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/NEW_20Manticore_20Flat_20Foot_20Gallery_207_u20j1r_b4b29d96-54b0-4c4d-b633-d4d2ecd50ca6.jpg?v=1766759029","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/Manticore_20Flat_20Foot_20Gallery_208_b7893e7d-7c7a-4789-8540-9c7d0ad29516.jpg?v=1766759029","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/Manticore_20Flat_20Foot_20Gallery_206_3d783914-4677-456c-bf5e-7f946f5e7c5c.jpg?v=1766759029","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/Manticore_20Flat_20Foot_20Gallery_209_c7d47771-98d7-411a-a8b0-9bd72230d799.jpg?v=1766759029"],"price":0,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:45.902Z"},"share_url":"https://firestarter.network/l/lst_sVp2fnjo","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
