{"type":"firestarter.listing","listing":{"id":"lst_Fsj06Nsw","product_name":"Kraken Rack Attachment for 4 Post Hydra & Manticore Racks (Single Side)","category":"Rack Attachment","description":"The Kraken is a compact rack-mounted cable system, turning your 3” x 3” 4-post power rack with ⅝” or 1” holes into a dual-handle cable tower with 5lbs to 210+lbs of resistance! All of this while maintaining the use of your barbell and rack attachments.It comes in two versions: - Plate-Loaded: use your weight plates to save big bucks- Weight Stack: a convenient 210-pound stack for quick, no-fuss adjustmentsThanks to the knurled handle, nylon rollers and chrome-coated pop pins, the trolleys are adjustable with a single hand. By using your uprights’ holes for height selections, you can fine-tune the feel of nearly all your cable exercises. The Kraken saves the clangin’ & bangin’ for your barbell lifts; its aluminum pulleys and dual guide rods deliver the kind of velvety smoothness you'd expect at a commercial gym — but without the crowds, the dude grunting in the corner, and that fit-fluencer hogging the Smith Machine for “just one more angle.”The dual aluminum handles have 6002 bearings, rotating as smoothly as a barbell, and allow bilateral exercises from a single upright. A single cable features a 2:1 pull ratio (10lbs feels like 5lbs), tackling everything from rehab work to isolations. Plus, the cable travel offers uninterrupted focus during sport-specific drills or while getting that joooooicy bicep pump. When connected with the cable adapter, the Kraken converts into a glorious 1:1 pull ratio — perfect for heavy lat pulldowns & low rows — with no need to buy a separate weight pack expansion down the road.Safety is no afterthought either — the Weight Stack version features an optional Shroud that does double duty: protecting fingers (big and small) AND acting as a pegboard, keeping your cable attachments neatly stowed using their included hooks. This means more family time while keeping your little ones safe… because a home gym shouldn't need a “Caution: Dangerous Sh*t EVERYWHERE” sign.A Single Side of the Kraken Includes:- Two aluminum handles- One cable ","images":["https://cdn.shopify.com/s/files/1/0654/3346/9125/files/4P-84H-STK-KRAKEN-SET-carousel-primary.jpg?v=1764593250","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/4_20post_20weight_20stack_20one_20side_20only.jpg?v=1764593250","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/Kraken_204_20post_20manticore_20rack_20weight_20stack_20one_20side_20only.jpg?v=1764593250","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/4_20post_20weight_20stack_20carousel-7.jpg?v=1764593250","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/4_20post_20weight_20stack_20carousel-8.jpg?v=1764593250","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/4_20post_20weight_20stack_20carousel-9.jpg?v=1764593250","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/4_20post_20weight_20stack_20carousel-10.jpg?v=1764593250","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/4_20post_20weight_20stack_20carousel-4.jpg?v=1764593250","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/4_20post_20weight_20stack_20carousel-1.jpg?v=1764593250","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/4_20post_20weight_20stack_20carousel-2.jpg?v=1764593250","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/4_20post_20weight_20stack_20carousel-3.jpg?v=1764593250","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/4_20post_20weight_20stack_20carousel-6_4da67f52-807c-4272-bbe0-722a854206ab.jpg?v=1764594115","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/4_20post_20weight_20stack_20carousel-5.jpg?v=1764593250","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/4_20post_20plate_20loaded_20one_20side_20only.jpg?v=1764593250","https://cdn.shopify.com/s/files/1/0654/3346/9125/files/Kraken_204_20post_20hydra_20rack_20plate_20loaded_20one_20side_20only.jpg?v=1764593250"],"price":1199.99,"currency":"USD","in_stock":true,"inventory_qty":79992,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:45.637Z"},"share_url":"https://firestarter.network/l/lst_Fsj06Nsw","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
