Product details

Olympic Machine Extenders + KingPin Combo

Push your training further with the GymPin Plate-Loading Expansion Bundle: a pair of 2" Olympic Machine Extenders plus two extra-long 10mm KingPins.

Designed for serious lifters who have outgrown the available loading capacity of their machines, this bundle gives you more room to load Olympic plates across compatible Hammer Strength-style plate-loaded equipment and 10mm selectorised cable machines.

The Olympic Machine Extenders slide inside compatible machine loading horns, adding over 6"/152mm of usable loading space per side. Use them for heavy leg presses, rows, chest presses, shoulder presses and other plate-loaded movements.

The KingPins replace the standard selector pin in compatible 10mm cable machines, allowing 2" Olympic plates to be loaded onto the extended sleeve. They are ideal for heavy rows, pulldowns, presses, curls, triceps work, and other cable exercises when the built-in stack is no longer enough.

Bundle includes

  • 2 × 2" Olympic Machine Extenders
  • 2 × KingPin 10mm weight stack extenders
  • Raw finish products as shown

Key benefits

  • Increase loading capacity without permanently modifying your equipment
  • Add over 6"/152mm per side with the Olympic Machine Extenders
  • Load 2" Olympic plates onto compatible cable machines with the KingPins
  • Built for serious home gyms, commercial facilities, bodybuilders and strength athletes
  • UK-designed GymPin products made for demanding training environments

Please check your machine dimensions and compatibility before ordering. The Olympic Machine Extenders are designed for compatible Hammer Strength plate-loaded machines, while the KingPin is suitable for compatible machines using a 10mm selector pin only. The KingPin has a recommended maximum load of 60kg; always load equipment evenly and train under control.

Why GymPin made it

GymPin products are created to solve practical training problems that lifters experience in real gyms.

The Extender & KingPin Bundle follows the same approach: useful equipment, solid construction and a clear purpose. No overcomplication. No unnecessary theatre. Just a product designed to make training better.

Our focus is on equipment that helps lifters train harder, set up faster, move better and get more from the machines, bars and accessories they already use.

Compatibility notes

Please check the product details, size options and compatibility information before ordering The Extender & KingPin Bundle.

Where relevant, make sure the product suits your machine, cable station, barbell, rack, loading pin, attachment point or training setup.

If your equipment uses non-standard sizing, unusual fittings or heavily customised parts, check measurements carefully before use. Gym equipment manufacturers love making “standard” things that are somehow not standard, because apparently chaos needed branding.

Important safety guidance

Always inspect The Extender & KingPin Bundle before use and make sure it is correctly fitted, positioned or attached before training.

Use controlled movement, sensible loading and stop using the product if anything feels loose, unstable or damaged.
