Overview
The Rogue RML-390F is the "flat-foot" version of the best-selling RML-390 Monster Lite Power Rack. It is specifically engineered for athletes who need a heavy-duty, commercial-grade power cage but cannot (or prefer not to) bolt their equipment into the floor. By utilizing a self-stabilizing base with a triangle-plate design, the RML-390F maintains a rock-solid foundation for heavy squats, benching, and pull-ups. Built from 3x3" 11-gauge steel, it offers a perfect balance of durability, modularity, and space efficiency for garage gyms and home training spaces.

Maintenance and Care
Level Surface: While the rack does not need to be bolted, it performs best on a level surface. Using 3/4" rubber horse stall mats is highly recommended to provide a stable, non-slip foundation.
Hardware Audit: Periodically check the 5/8” hardware to ensure all bolts remain tight, especially after performing high-vibration movements like kipping pull-ups.
UHMW Protection: Regularly inspect the UHMW plastic on the J-cups and safeties. Replace the liners if they wear thin to prevent metal-on-metal contact with your barbell.
Surface Care: Clean the Matte Black frame with a damp cloth and mild soap. Avoid abrasive chemicals.
Rust Prevention: If located in a garage or basement with high humidity, wipe down moisture after workouts and touch up any significant scratches in the powder coat with a matching black paint.
Warranty Information
Frame and Welds: Limited Lifetime Warranty.
General Parts: 5-Year Warranty on most mechanical attachments.
Frequently Asked Questions
Q: Is it safe for kipping pull-ups?
A: Yes, the flat-foot base is very stable for pull-ups. However, for maximum peace of mind during aggressive kipping, many users choose to add weight plate storage pins to the rear of the rack to act as ballast.
Q: Can I use Safety Spotter Arms on this rack?
A: Rogue generally recommends against using Safety Spotter Arms (which hang off the front) on unbolted racks due to the risk of tipping. It is safest to use the included Pin/Pipe safeties inside the cage.
Q: What is the difference between this and the RML-3?
A: The RML-3 is a bolt-down rack that uses 2x3" steel for the base crossmembers. The RML-390F uses a 3x3" flat-foot base and does not require anchoring.
Q: Does it fit in a room with an 8-foot ceiling?
A: Yes. The total height is 92.25", which leaves nearly 4 inches of clearance in a standard 96" (8ft) high room.
