A solid base for your CS-1 power rack
The 104 cm rack uprights from the CS-1 range have been designed to offer stability, safety and modularity. Their thick steel construction ensures excellent hold under load, even in intensive set-ups (squats, presses, weighted pull-ups).
The 104 cm format is ideal for compact racks, half-racks or wall-mounted configurations, while retaining a wide range of exercises.
Precision and everyday ease of use
The laser-cut markings make it easy to position J-cups, safety arms or accessories symmetrically. The regular hole spacing guarantees precise, quick adjustment, essential for moving through your sessions without wasting time.
This precision is particularly appreciated for structured strength, hypertrophy or cross-training work.
Full compatibility with CS-1 accessories
These uprights are fully compatible with the accessories in the CS-1 range:
J-cups, safety arms, pull-up bars, pulleys, landmine, storage supports or leg accessories.
They fit perfectly into the logic of an upgradeable rack, which you can develop as your goals evolve without replacing your structure.
Who is it for?
The uprights from the CS-1 rack range 104 cm are equally suited to:
-
demanding lifters in a home gym,
-
coaches and gyms looking for a reliable structure,
-
users wanting a modular, long-lasting rack with no compromise on safety.
Unmatched modularity and compatibility
The 75 x 75 mm (3 x 3”) format is a recognised standard in the world of high-end power racks. On the CS-1 range, we have kept the strength and architecture of our historic uprights while developing their drilling with a keyhole design.
This design delivers extended compatibility with the vast majority of accessories for 75 x 75 mm (3 x 3”) racks available on the market, whether they use 26 mm (1”) or 16 mm (5/8”) fixings. Thanks to this dual compatibility, the rack becomes more versatile, more upgradeable and simpler to develop over time.
The uprights in the CS-1 range are drilled on all 4 faces, which increases the configuration possibilities and lets you make the most of the advantages of a modular 75 x 75 mm (3 x 3”) power rack. The rack can therefore adapt to your training, your space and the way your needs evolve, without limiting you to a single standard or a single accessory brand.
This modularity makes it easy to add, for example, roller J-cups, a high pulley / low or adjustable, a Smith Machine, dip bars or other training accessories. It also lets you develop your set-up from a classic configuration to a 6-upright extension.
By choosing a 75 x 75 mm (3 x 3”) rack with keyhole drilling, compatible with 1” and 5/8”, you are opting for a durable, upgradeable solution designed to maximise compatibility with our own accessories as well as those from other manufacturers.
