Rogue RML-390F Flat Foot Monster Lite Power Rack Review

Updated January 1, 2019

The Rogue RML-390F Flat Foot is a slightly pared down version of the RM-390 Flat Foot. While it features the same robust 3 x 3 inch square, 11-gauge steel framing, the hardware is slightly less hardcore, with ⅝ inch hardware as opposed to one inch diameter bolts on the RM-390. As with the larger version you do not need to bolt this unit down, making it more portable and versatile than the other units in the Rogue stable.

Let’s get a closer look at the Rogue RML-390F Flat Foot.

The Rogue RML-390F Flat Foot Monster Lite Up Close

The Rogue Monster Lite Flat Foot can be used as a stand alone unit or it can be converted using an existing SML-2 or SML-3 squat rack. The rack has a special triangle base set-up which provides you with a superior level of balance and rigidity. That means that you don’t have to bolt this unit to the ground, giving you a lot of flexibility as to where you locate the rack.

Rogue Monster Lite Flat Foot features 3 x 3 inch, 11-gauge square steel tubing. That is as heavy duty as it gets with Rogue and provides you with extremely high end rigidity. The bolts to put this thing together are ⅝ inch in diameter. While not as hardcore as the one inch bolts used on the RM-390 F, it still provides you with all the structural integrity you will ever need. The foot-print of this unit is quite conservative, at 48 x 49 inches. Even still, it gives you a generous 30 inch walk in space.

You get a good level of customization choice with this unit. You can select between a single skinny or fat/skinny 43 inch pull up bar. Pin pipe safeties come as standard and you get a pair of high quality j-cups. This rack also makes use of the Westside hole spacing system, so you get one-inch hole spacings during the bench press zone and two inch spacings between the upper and lower portions.​


  • Doesn’t need to be bolted down
  • Generous walk in space
  • Westside hole spacing


  • No built in safety system
