{"type":"firestarter.listing","listing":{"id":"lst_b0nq_yKC","product_name":"Manticore Four Post Converter Bench","category":null,"description":"The four-post bench station is what you see at powerlifting meets and serious commercial gyms. It’s a dedicated bench press station, made your way when you add your favourite safeties and j-cups — and the Converter Bench makes it happen.What makes this one different from the competition is the floating bench design.The Converter Bench hangs between the specialty crossmembers with ZERO POSTS UNDERNEATH. That means you can tuck your feet back as far as you want without hitting anything. For powerlifters who rely on leg drive, this is a big deal.Add your choice of roller J-cups, sandwich J-cups, regular J-cups, and safeties — spec this station out however you want. For more versatility, grab 4 Manticore Mag Pins (Full Length), so when you’re done benching, you can pop the pins, wheel the bench out, and use the uprights for other attachments. Dips. Seal rows. Whatever.60\" Manticore uprights built with the 3”x3” and 1\" hole cross-brand compatibility you know and love (or hate, if you work for a competitor.) Looking for 5/8\" holes? We make a 60\" Hydra version, too. Either way, you’re getting IPF competition height and a four-post station that’s more versatile than anything else on the market.This setup includes the Converter Bench and a pair of specialty 43\" crossmembers (also available separately). Choose your j-cups and safeties to seal the deal. It’s also compatible with the spotter deck we’re developing so your favourite hander-offer (technical term) can get in on the action.","images":["https://cdn.shopify.com/s/files/1/0654/3346/9125/files/4post-cnvt-mtc-set-01.jpg?v=1777321578","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/4post-cnvt-mtc-set-02_8c2cbc3e-7d99-43a1-abaa-f4254a4db9c9.jpg?v=1777321579","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/4post-cnvt-mtc-set-03_1f50b3e0-7936-4b0c-9b4c-f368730de2d7.jpg?v=1777321579","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/4post-cnvt-mtc-set-04_86aec30a-0bad-4e33-88a9-09dfc36c0b9a.jpg?v=1777321579","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/4post-cnvt-mtc-set-05_a154facd-2444-45ff-9630-5c3a517e4aa4.jpg?v=1777321579","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/4post-cnvt-mtc-set-06_eff091a5-809d-44ae-9421-50a214dada8c.jpg?v=1777321579","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/4post-cnvt-mtc-set-07_474e1189-a7a7-4244-9ea0-1198559d017e.jpg?v=1777321579","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/4post-cnvt-mtc-set-08_1f8de6b0-d9ba-4ba5-8b41-ad5b1a7d3d4c.jpg?v=1777321579"],"price":1034.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:45.228Z"},"share_url":"https://firestarter.network/l/lst_b0nq_yKC","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
