H-Series FS 04 - Free Standing Rig

The NC Fitness H-Series FS 04 is a commercial-grade free standing gym rig spanning 4.25 metres wide — a self-supporting, floor-anchored structure that delivers the full training capability of a wall rig without requiring wall attachment. Built from extra-heavy 80 x 80 x 4mm steel uprights and 8mm steel components throughout, the FS 04 is engineered for CrossFit boxes, functional training facilities, PT studios, and serious home gym installations across Melbourne and Australia. Local pickup available from our Keysborough warehouse.

Important installation note: This rig must be bolted to the floor. The buyer is responsible for confirming that the floor structure is rated for this application. Floor bolts are not included due to the variability in floor types and anchor requirements. We strongly recommend engaging a structural engineer or licensed builder to assess your floor prior to installation. For guidance on structural requirements for gym equipment installation in Australia, refer to the Australian Building Codes Board (ABCB).

Free Standing vs Wall Mounted: Which Is Right for You?

The key advantage of a free standing rig over a wall mounted rig is installation flexibility. The FS 04 does not require wall anchoring — making it suitable for facilities where wall structure cannot be confirmed, where the rig needs to be positioned away from walls, or where future relocation is a consideration. It requires only floor anchoring, which is typically simpler to engineer across a wider range of building types.

The trade-off is footprint: the FS 04’s 1.24m depth accounts for the rear uprights that replace the wall as the structural support. For facilities with sufficient floor space, the free standing configuration offers greater placement flexibility and equivalent structural performance to a wall mounted rig of the same steel specification.

Frame Construction

The FS 04 is built from 80 x 80 x 4mm steel uprights — the same commercial specification used across the H-Series wall mounted rig range. The 4mm wall thickness delivers significantly greater rigidity and load capacity than the 2–3mm steel found in entry-level and mid-range rigs. With 8 upright columns (versus 6 in the WM 07 wall rig), the FS 04’s free standing structure distributes load across a larger number of anchor points, maintaining structural integrity under the dynamic forces generated by kipping pull-ups, bar muscle-ups, and barbell cycling.

The pull-up bar height is adjustable in 50mm increments, accommodating athletes of different heights and different movement standards. The unit can also be shortened in height to suit facilities with lower ceiling clearance — a practical consideration for garage gyms and converted commercial spaces.

Training Applications

The FS 04’s 4.25m width and 4 J-hook pairs enable multiple simultaneous training bays across a full range of barbell and bodyweight movements:

• Barbell squats — back squat, front squat, and overhead squat from the J-hooks. The free standing design allows the rig to be positioned centrally in a training space for access from both sides.
• Pull-ups and chin-ups — strict, kipping, and butterfly pull-ups across multiple pull-up bar positions. The adjustable bar height accommodates different athlete heights and movement standards.
• Bar muscle-ups — the commercial-grade 80x80x4mm steel and floor anchoring provide the structural rigidity required for the dynamic loading of kipping muscle-ups.
• Ring work — gymnastics rings can be hung from the cross beams for ring dips, ring rows, ring muscle-ups, and L-sits across the 1080mm and 1770mm cross beam positions.
• Barbell pressing — bench press and overhead press with a bench positioned under the rig. The 4 J-hook pairs allow multiple rack heights to be set simultaneously for different athletes.
• Rack pulls and partial deadlifts — J-hooks set at various heights for partial range pulling movements and pin pulls.
• Functional training and conditioning — battle ropes, resistance bands, and suspension trainers can be anchored to the rig frame. The free standing configuration allows 360-degree access around the rig for functional training circuits.

For programming guidance on rig-based training, the ACE Fitness Exercise Library provides technique guides for pull-up, ring, and barbell rack movements.

Who Is the FS 04 For?

• CrossFit boxes and functional training facilities — the 4.25m width accommodates 2–3 simultaneous training bays. The free standing design allows flexible placement within the training floor without wall anchoring constraints.
• PT studios — a complete multi-bay rig for group and individual training in a single footprint. The 4 J-hook pairs allow multiple rack heights to be configured simultaneously for different clients.
• Commercial gyms — a space-efficient alternative to multiple individual power racks, delivering equivalent training capacity in a single integrated structure.
• Serious home gym installations — for dedicated gym rooms, garage gyms, or shed installations where wall anchoring is not possible or practical. The FS 04 delivers a commercial-grade training environment with floor anchoring only.

Installation Guidance

Free standing rigs require secure floor anchoring to prevent movement under dynamic loading. Key considerations for Australian installations include:

• Floor anchoring — floor bolts are not included due to variability in concrete slab thickness, timber subfloor construction, and anchor requirements. A structural engineer should specify appropriate anchors for your floor type and slab depth.
• Concrete slab — a minimum concrete slab thickness of 100mm is generally recommended for gym equipment anchoring, though specific requirements depend on the anchor type and load. Consult a structural engineer for your specific installation.
• Ceiling clearance — the standard height of 2.435m suits most commercial and residential ceiling heights. The 3.49m extended height requires a minimum ceiling clearance of approximately 3.6–3.7m to allow safe overhead movement above the rig.
• Rubber flooring — install the rig on appropriate rubber gym flooring to protect the floor surface and reduce vibration transfer. A minimum 15mm rubber tile thickness is recommended under and around the rig footprint.
• Australian Standards — commercial gym equipment installation should comply with AS 4633:2005 (Fitness Equipment — Safety Requirements and Test Methods) and relevant building codes. Consult your local council and a licensed builder for commercial installations.

Additional charges

There may be additional charges to your freight if you have selected the wrong shipping method, if you request a specific delivery time, if for example you have a steep driveway or the courier requires 2 drivers to unload your items.

Delivery can be made in Australia wide & delivery times are guidelines and are never guaranteed. NC Fitness will not offer compensation for any delivery that arrives later than the estimate given.
All deliveries are authorised to leave at the property unless instructed otherwise.
Our aim is efficient delivery; once it has been passed to the courier company, some deliveries may be late due to your location, accidents or local disruptions. In these instances, we NC Fitness will not be liable for any consequential loss for delivery times. If your order looks damaged on delivery, please check your delivery before signing for it. Inform the delivery driver of the damage and ask them to sign the damage.

Bulk/Heavy Deliveries

Delivery drivers DO NOT carry heavy items upstairs due to safety risks, including potential injuries from lifting or falling. Liability concerns also play a role, as companies don’t want to be responsible for property damage or worker injuries during delivery. All Bulk/Heavy Deliveries are considered Curbside Delivery, which means the delivery driver drops off your item at the nearest accessible point by the curb, driveway, or sidewalk. They do not bring it inside, upstairs, or assemble it. You’re responsible for moving it indoors.
