Overview
The Rogue FML-6 Twin Functional Trainer Add-On is a transformative conversion kit designed specifically for owners of the RML-690 Monster Lite Power Rack. This upgrade integrates two independent weight stacks into the rack’s frame, providing a vertically adjustable 2:1 ratio functional trainer along with a 1:1 ratio lat pulldown and low row station. By positioning the weight stacks on the sides, the "Twin" configuration maintains a minimized footprint—extending only 5” behind the rack—making it an ideal "all-in-one" solution for high-performance home and commercial gyms.

Independent Resistance: Two weight sources allow two users to work simultaneously on different cable movements or ensure perfectly balanced bilateral training for a single user.
Space-Efficiency: Replaces up to six separate pieces of equipment within the footprint of a single power rack.
Monster Lite Compatibility: Retains the core functionality of the RML-690, including Westside hole spacing and compatibility with a vast range of Monster Lite accessories.
Maintenance and Care
Floor Anchoring: This unit must be securely bolted to the floor using a concrete anchor kit to handle the additional weight and mechanical leverage.
Guide Rod Lubrication: Clean the chrome-plated guide rods monthly with a lint-free cloth. Apply a thin layer of silicone-based lubricant to ensure a smooth, silent glide for the weight stacks.
Cable Inspection: Regularly inspect the 3/16" aircraft cable for signs of fraying, kinking, or coating cracks. Replace cables immediately if damage is found.
Hardware Audit: Monthly verification of all 5/8” bolts and pulley hardware is recommended to ensure they remain tightened to Rogue's specified torque.
Cleaning: Wipe down the powder-coated frame with a mild soap and water solution. Avoid using abrasive chemicals on the aluminum pulleys or custom finishes.
