Commercial Power Rack Core
The KB2404 is built on a foundation of commercial-grade construction.
3"×3" 9-Gauge Steel Frame
The 9-gauge (3.2mm) steel construction exceeds the thickness of standard 11-gauge (2.5mm) racks, providing superior strength and rigidity. The 1,500LB+ static capacity handles whatever weight you can lift, while the robust structure supports the integrated cable systems without compromising rack integrity. This is commercial-grade construction designed for commercial-grade training.
Multi-Grip Pull-Up Bar
The integrated pull-up station features multiple grip positions—neutral, wide, and narrow—for complete back development. Train pull-ups and chin-ups with varied hand positions to target different areas of the back and arms. The multi-grip design accommodates different shoulder widths and training preferences.
Laser-Cut J-Cups & Safety Arms
Precision laser-cut J-cups provide secure barbell storage and proper positioning for various exercises. The safety arms offer fail-safe spotting for solo training, allowing you to push to failure safely. The precise manufacturing ensures consistent fit and reliable performance through years of heavy use.
Integrated Weight Stack & Cable System
The KB2404's cable system provides versatile training options through multiple configurations.
330LB Cast Iron Weight Stack
The commercial-grade cast iron weight stack provides smooth, consistent resistance for all cable exercises. The 330LB capacity handles most training needs, and the stack is expandable to 550LB for advanced lifters and progressive overload training. Each weight plate is precision-machined for smooth operation and accurate resistance.
Dual Pulley Configuration
2:1 Ratio Individually: Use each pulley independently for controlled, unilateral movements. The 2:1 ratio means 165LB of resistance per side—ideal for isolation exercises, rehabilitation, and unilateral training.
1:1 Ratio Paired: Pull both cables together for heavier compound cable work. The 1:1 ratio delivers the full weight stack resistance for exercises like cable squats, heavy rows, and pressing movements.
Tornado Arms Configuration
2:1 Ratio Only: The Tornado Arms provide smooth, consistent resistance across a wide range of dynamic movement patterns. The adjustable arms enable crossover exercises, sport-specific training, and functional movements that fixed pulleys cannot provide. Choose this configuration for maximum exercise variety and dynamic training.
Center Lat & Low Row Station
Dual-Pulley Design: The center station provides dedicated lat pulldown and low row capability. Use individual pulleys at 2:1 ratio for controlled single-handle work, or pair them at 1:1 ratio for heavier lat pulldowns and rows. This station delivers the back training essential for complete upper-body development.

Key Training Benefits
The Spartaks Strength KB2404 delivers benefits that make it the centerpiece of any training facility.
Complete Training Versatility
One machine provides what would otherwise require a power rack, cable crossover, lat pulldown machine, low row machine, and pull-up station. This consolidation saves significant floor space and equipment cost while providing comprehensive training capability. From powerlifting to bodybuilding to functional fitness, the KB2404 handles every training style.
Commercial-Grade Durability
The 9-gauge (3.2mm) steel construction exceeds the thickness of standard 11-gauge (2.5mm) racks, providing superior strength and rigidity. This heavier steel withstands the abuse of commercial environments while providing the stability needed for maximum-effort lifts. The powder-coated finish resists wear and corrosion for long-term aesthetics.
Smooth, Quiet Operation
The aircraft-grade aluminum pulleys with sealed bearings provide silky-smooth cable movement. Unlike plastic pulleys that create friction and noise, these precision components deliver consistent resistance with minimal maintenance. The smooth operation enhances the training experience and protects your joints from jerky resistance changes.
Progressive Overload Support
The expandable weight stack supports long-term strength development. Start with the standard 330LB capacity and expand to 550LB as your strength increases. The multiple cable ratios provide appropriate resistance for both isolation work and heavy compound movements, enabling systematic progressive overload programming.
Multi-User Capability
The dual-station design allows multiple users to train simultaneously. Someone can perform barbell work in the rack while another uses the cable system—maximizing equipment utilization in commercial settings. This capability is particularly valuable during peak hours when equipment availability matters.

Frequently Asked Questions About the KB2404
What is the difference between dual pulleys and Tornado Arms?
Dual pulleys offer two cable ratios: 2:1 when used individually for isolation work, and 1:1 when pulled together for heavier compound movements. Tornado Arms provide 2:1 ratio only but offer adjustable positioning for dynamic movement patterns, crossovers, and sport-specific training. Choose dual pulleys for maximum resistance versatility, or Tornado Arms for functional movement variety.
What does the 2:1 and 1:1 cable ratio mean?
A 2:1 ratio means you feel half the selected weight at the handle—selecting 100LB provides 50LB of resistance. This is ideal for isolation exercises and controlled movements. A 1:1 ratio means you feel the full selected weight—ideal for heavier compound movements. The KB2404 offers both ratios, allowing appropriate resistance for different exercise types.
Can I expand the weight stack?
Yes, the 330LB cast iron weight stack is expandable to 550LB. This expandability allows the machine to grow with your strength, providing long-term training value. As you progress, add additional weight plates to increase the maximum resistance available for all cable exercises.
What is the weight capacity of the rack?
The KB2404's 3"×3" 9-gauge steel construction provides a 1,500LB+ static capacity. This exceeds the capacity of standard 11-gauge racks and handles whatever weight serious lifters can use. The robust construction ensures safe training at any weight level, whether you're powerlifting, bodybuilding, or training for general fitness.
Can multiple people use this machine at once?
Yes, the dual-station design allows multiple users to train simultaneously. Someone can perform barbell exercises in the rack while another uses the cable system. The side cable stations operate independently, and the center lat/low row station is separate from the side stations. This multi-user capability maximizes equipment utilization in commercial settings.
What attachments are included?
The KB2404 includes a multi-grip pull-up bar, laser-cut J-cups, and safety arms. Standard cable attachments such as handles, bars, and ropes may be included or available separately—check with us for current package details. The 1" holes accept most standard rack attachments, allowing you to expand training options with accessories.
Do you ship to Ontario and Quebec?
Absolutely! We offer free local pickup at our Toronto (GTA) showroom—we encourage visiting to see equipment before purchase. For customers outside the GTA, we ship throughout Ontario and Quebec, including Ottawa, Hamilton, Mississauga, Montreal, Quebec City, Kingston, London, and all surrounding areas.
