THE TRADE-OFF IS PRESENTATION, NOT PURPOSE.

Product details
GymPin Internal Machine Extenders
GymPin Internal Machine Extenders are designed to add extra loading space to compatible Hammer Strength and Cybex plate loaded gym equipment. Simply slide the extenders inside the existing machine weight horns to create a longer loading bar, giving you more room to add Olympic weight plates during heavy strength training sessions.
Designed and manufactured in the UK, these heavy-duty machine extenders are built from high-quality materials and made for serious gym environments. They are used by bodybuilders, powerlifters and strength athletes who need more plate loading capacity from their existing equipment without changing the machine.
Add More Weight to Plate Loaded Gym Equipment
Each extender adds over 6 inches / 152mm of usable loading length per side, making them ideal for high-level leg presses, chest presses, rows, shoulder presses and other compatible plate loaded machines where the standard loading horn is no longer enough.

B-GRADE QUESTIONS, ANSWERED.
WHAT CAN MAKE AN INTERNAL EXTENDER B-GRADE?
Possible reasons include surface, machining, finish or packaging imperfections. These affect presentation rather than the intended loading function.
DO I NEED THE 34 MM OR 37 MM VERSION?
Measure the relevant part of your machine and use the compatibility wording shown against each variant. Do not assume fit from the machine brand alone.
HOW DOES B-GRADE STOCK WORK?
Each variant stays unavailable until an inspected pair is entered into inventory. Availability can differ by finish and diameter.
