Overview
The Rogue FM-6 Twin Functional Trainer Add-On is a premier conversion kit designed to transform an existing Rogue RM-6 Monster Rack into a dual-stack training powerhouse. This system integrates two independent weight stacks on the sides of the rack, delivering a vertically adjustable 2:1 ratio functional trainer. A key innovation of the "Twin" model is its ability to internally combine the output from both stacks, providing up to 300 LB of total load for lat pulldown and low row exercises. By leveraging the rack's side space, it maintains a compact overall depth while offering commercial-grade cable versatility.

Key Features and Specifications
Compatibility: Specifically engineered for the Rogue Monster Series (3x3" 11-gauge steel) RM-6 Power Racks.
Dual Weight Stacks: Available in dual 250 LB or 300 LB stack configurations.
Advanced Pulley Configuration:
2:1 Ratio: Front adjustable trolleys (150 LB effective resistance per side with 300 LB stacks).
Combined Load: Internally bridges both stacks to provide 1:1 feel for lat pulldown and low row.
Cable Quality: 3/16" US-made Military Spec Aircraft Cable.
Footprint Efficiency: Reduces depth by positioning weight stacks on the sides, extending only 3.5” behind the back of the rack.
Adjustability: Features four precision-machined rollers on the trolley for effortless vertical movement and swiveling pulleys for optimal angles.
Hardware: 1" oversized hardware and 1/4" steel pulley plates.
Manufacturing: Made in the USA with imported pulleys.
Performance Benefits
Ultimate Versatility: Transitions seamlessly between single-arm cable work, dual-arm functional training, heavy lat pulldowns, and low rows without reconfiguring any cables.
Independent Resistance: Dual weight sources allow for independent unilateral training, ensuring that the stronger side cannot compensate for the weaker side.
High-Capacity Pulling: Unlike single-stack trainers, the Twin configuration combines the power of both stacks for high-load pulling movements, reaching up to 300 LB for back development.
Space Optimization: The "behind the rack" profile is minimized, allowing for more room in the center of the gym while keeping the weight stacks protected and accessible.
Smooth Commercial Feel: Larger pulleys and high-grade rollers result in a friction-free experience that matches high-end commercial gym equipment.
Maintenance and Care
Bolting Requirement: The host RM-6 rack must be securely bolted to the floor to support the additional weight and dynamic leverage of the dual stacks.
Cable Tensioning: During assembly, ensure the cables are properly tensioned so the top weight plate rests flat on the stack. Re-check tension after the first 30 days of use as cables may experience a minor "break-in" stretch.
Lubrication: Wipe down the weight stack guide rods monthly and apply a thin coat of silicone-based lubricant to ensure a silent and smooth glide.
Hardware Audit: Regularly inspect the 1" hex nuts and 3/8" pulley bolts to ensure they remain tightened to Rogue’s specifications.
Stack Care: Keep the weight stacks free of dust and chalk. If shrouds are installed, periodically remove them to inspect the internal pulley paths and cable integrity.
Warranty Information
Structural Welds and Frame: Limited Lifetime Warranty.
Pulleys, Cables, and Guide Rods: 5-Year Warranty.
Frequently Asked Questions
Q: Does this include handles or a lat bar?
A: Standard handle attachments are typically optional. You can customize your order by selecting lat bars, low row triangles, and functional handles in the purchase area.
Q: Can I perform seated rows with the Twin Add-On?
A: Yes, a removable low row bracket and footplate are included as part of the system.
Q: Is there a seat for lat pulldowns?
A: A dedicated seat is not standard. The Rogue Monster Multi-Use Rack Roller is recommended to serve as a thigh catch when using a flat bench.
Q: How much ceiling height is required?
A: Assembly requires a minimum of 95" or 105" of total height depending on whether you have a 90" or 100" upright configuration.
