NEXUS functional trainers combine a squat rack, pull-up station and 120kg cable stacks in one modular 3 or 5 Series system for home, PT and commercial gyms.
NEXUS Functional Trainers: Squat Rack and Cable Machine in One
A functional trainer combines a squat rack, pull-up station and cable columns in one frame, so barbell, bodyweight and cable training can all happen in the same footprint. The BLK BOX NEXUS range builds that onto our 3 Series and 5 Series rack platforms, with integrated 120kg cable stacks, for home gyms, PT studios, commercial facilities and elite performance spaces. Every NEXUS Rack is designed, manufactured and assembled at BLK BOX HQ in Belfast, backed by a lifetime structural warranty on the uprights.
NEXUS Specifications
Every NEXUS cable stack is 120kg as standard, with a 150kg option available on enquiry, and runs on a 2:1 pulley ratio for smooth, consistent resistance. 3 Series NEXUS racks use 70x70x3mm uprights with 75mm hole spacing at 2.2m or 2.4m high; 5 Series NEXUS racks move to 80x80x3mm uprights with Westside hole spacing (37.5mm and 75mm) at 2.3m or 2.5m. Racks are 1.2m wide, with wall mounted and compact versions 0.8m deep and full versions 1.9m deep.
NEXUS Configurations
Wall Mounted and Compact NEXUS Racks
Wall mounted and compact NEXUS racks pair one squat station and one pull-up station with a single 120kg cable column on a 0.8m-deep footprint. Wall mounted versions fix to a suitable wall for the smallest footprint in the range, compact versions are available with integrated storage, and the 3 Series Freestanding Compact NEXUS Rack needs no floor fixings.
Full NEXUS Racks with Dual Cable Stacks
Full NEXUS racks add twin cable columns, two squat bays and two pull-up stations at 1.9m deep, performing as a power rack and dual cable machine for cable crossovers, lat pulldowns, rows, curls and rehabilitation work alongside squats, bench press and pull-ups. The 3 Series Freestanding NEXUS Full Rack adds eight storage pegs and rear barbell storage with no floor fixings.
Combo and Back-to-Back NEXUS Racks
Combo racks join two rack types side by side, in Full/Full, Full/Compact, Full/Half, Compact/Compact, Compact/Full and Compact/Half layouts, while back-to-back NEXUS racks place two stations facing opposite directions, each with its own 120kg stack, in a footprint far tighter than two separate racks.
NEXUS Testing Racks and Upgrade Kits
NEXUS Testing Racks combine the cable system with an integrated Smith machine and ISO attachment for independent barbell movement. If you already own a 3 Series or 5 Series rack, a NEXUS Upgrade Kit retrofits cable columns to compact or full racks, matched to 70x70x3mm or 80x80x3mm uprights. Our NEXUS rack buying guide compares every configuration.
Modular and Built to Grow
NEXUS is designed around a modular platform compatible with the wider BLK BOX attachment ecosystem, so it can be expanded with storage and training attachments as your programming develops. For a more traditional setup instead, compare against our squat racks and power racks or browse the full gym rigs range.
Can I combine a squat rack and cable machine in one system?
Yes. NEXUS combines a squat rack, pull-up station and cable machine in one modular system. The range uses 3 Series or 5 Series rack platforms with integrated cable stacks, allowing barbell, bodyweight and cable training from the same footprint.
Can two people use separate stations at the same time?
Yes, depending on the configuration. The full NEXUS rack provides two squat bays, two pull-up stations and dual cable stacks, supporting simultaneous training on separate stations when the exercises do not interfere. Compact versions provide one squat and one pull-up station and therefore have lower simultaneous capacity.
Which NEXUS configuration suits my room and training?
Choose the NEXUS configuration from available floor area, number of users and whether you need one or two squat bays. Compact and wall-mounted versions reduce depth, while full, combo and back-to-back formats add more stations for PT studios, commercial gyms and elite performance spaces. 3 Series suits modular commercial use; 5 Series adds Westside spacing and advanced performance options.
Should I buy a complete NEXUS system or upgrade my rack?
Buy a complete NEXUS system when you need a new rack and cables together. Use an upgrade kit when you already own a compatible current 3 Series or 5 Series rack and want to add cable functionality without replacing the full rack.
What is included in a NEXUS setup and what costs extra?
A complete NEXUS configuration includes the rack structure and integrated cable system specified for that setup; storage, attachments, benches and cable handles vary by configuration and may be extra. Use the final configured equipment list rather than assuming every NEXUS system includes the same accessories.
What working clearance is needed around the chosen NEXUS configuration?
Start with the rack footprint, then allow barbell loading space, cable travel and user circulation. Wall mounted and compact NEXUS racks are 1.2m wide and 0.8m deep, and full racks 1.2m wide and 1.9m deep; the working area must be larger than those fixed footprints.
What pulley ratio applies and how does it affect working resistance?
NEXUS cable stacks are 120kg as standard with a 2:1 pulley ratio; compact and wall mounted racks have one cable column, while full and back-to-back racks have twin columns. A 150kg stack is available on enquiry. Use the resistance stated for the exact NEXUS configuration rather than assuming all cable machines share the same effective loading behaviour.
Which rack generation is required for the NEXUS upgrade kit?
The current NEXUS upgrade platform is for compatible 3 Series and 5 Series racks. Match the exact rack type, series and height to the upgrade kit; do not assume older Goliath or Samson racks are compatible with a current NEXUS kit without confirmation.
Does this configuration require wall or floor anchoring?
Anchoring follows the rack configuration and installation guide. 5 Series racks require bolting to the wall or ground; wall-mounted NEXUS must also be fixed to a suitable structure, while the 3 Series Freestanding NEXUS Full and Compact Racks need no floor fixings. Confirm the exact anchoring requirement for the selected 3 or 5 Series configuration before installation.
Which handles, safeties and bench accessories are included?
Included handles, safeties and bench accessories vary by NEXUS product. Treat the rack, cable system and stated included components as the base, then check whether J-Hooks, safeties, cable handles, storage and bench are included or need to be added separately in the configured quote.
How does the complete configured price compare with separate rack and cable units?
Compare the complete configured NEXUS price with the cost and floor area of a separate rack plus a standalone cable machine, not just the frame prices. NEXUS is strongest where combining both functions in one footprint reduces duplication, while separate units can make more sense if several users need independent stations at the same time.
What service and replacement-part support is available for the cable system?
Service and replacement support depends on the NEXUS model and cable components. Inspect cables and pulleys for wear and use the product model or SKU when requesting parts or maintenance support.
Is the Nexus rack for a home or commercial gym?
The Nexus rack lineup offers high-quality racks across the 3 and 5 series for both home and professional gyms with the NEXUS functional trainer range combining free weight with cable-strength training.
How much clearance do I need from the wall when installing the Series 3 and Series 5 racks?
We recommend allowing 300mm of space from the wall on either side of the plates to provide clearance for the bumper storage.
What attachments can I add to a BLK BOX squat rack?
You can add a wide range of attachments including pull‑up/dip bars, landmine attachments, weight plate storage pegs, cable systems, safety arms, and more.
What customisation options are available for the 5 Series?
The 5 Series is fully customisable - from colour and laser-cut branding to stainless steel construction, J-Hook colour accents, and stack guards. It’s the most tailored range in the BLK BOX lineup.
How can I cover my exercise list without buying duplicate equipment?
A NEXUS functional trainer combines a squat rack, pull-up station and cable column in one footprint, so barbell, bodyweight and cable exercises share one frame instead of needing a separate rack and cable machine. Attachments and storage then extend it as your training develops.
