RML-390F Flat Foot Monster Lite Rack

RML-390F Flat Foot Monster Lite Rack

The RML-390F is the Flat Foot version of the RML-3 Monster Lite Power Rack. Available as a stand-alone unit or by converting an existing SML-2 or SML-3 Squat Stand, this rack's self-stabilizing base means you won't need to bolt it to the ground before you use it—a major benefit for those looking to protect their floors or to have more flexibility in a workout space. The Flat Foot Monster Lite Rack is manufactured in Columbus, OH, and features 3x3" 11-gauge steel uprights, 2x3" 11-gauge steel bases with Westside hole spacing and 5/8" bolts and fasteners. Leaving just a 48" x 49" footprint, the unit still creates a substantial 30" of inside depth. Customers can choose between a Single Skinny or Fat/Skinny 43" Pull-up Bar, and all orders come standard with a pair of Monster Lite J-Cups and a pin/pipe safety system.

This rack is perfect for my current setup. 1st floor (one level up) spare bedroom. No need to bolt down, and spreads the weight along the feet (I assume). As others have mentioned, it does have some potential downsides. Not being a "standard" rack, some attachments won't work, and extending to a 6-post is non-trivial. You'll want Sandwich J-cups to help with the width, and a silver sharpie to write some hole numbers. Note: You can email Rogue to switch attachments out at time of purchase. I wish they just had this available directly on their website. I suggest a) Sandwich J-cups b) Strap safeties c) Socket pullup bar. The last potential con is that some attachments only cater for 1" holes. I've not found that to be an issue, but worth considering.

While this rack has endured 10 years of free weight compounds without issue, the industry has advanced, hurting this product's overall value. I still prefer 5/8" holes and Westside spacing but seemingly, most gym equipment companies do not. That, plus the scarcity of 4-way holes, restricts the potential for storage/utility upgrades. I've resorted to fabrication and customization to work around such limitations but if I was starting over? I'd invest in the 1in hole ecosystem favored today.

I’ve had this rack for 5 years and I’m completely satisfied with it. When I first started looking for racks I was contemplating cheaper racks from other brands, but I decided to go with the Rogue Monster Lite line with the 5/8 holes and west side hole spacing. I didn’t want a rack I would have to bolt to the ground, but I still wanted something sturdy. This totally fits the bill! In instillation as pretty straight forward and pretty easy to do. It’s heavy enough to stays put pretty well. If you’re slamming the weight into the Jcups you may move it a little over time, especially if you’re not on rubber floors. This is a great and safe rack, the only thing you can’t really do with a flat foot rack is use band pegs for band work. I mean; you can, but you risk potentially lifting/moving your rack if you’re strong enough as the rack weighs 295lbs. Also, I don’t think you’re supposed to use attachments like the Pritchett pad either. So it does have its limitations. Just like anything, there is a give and take. I do believe that you can buy some mounting brackets if you do decide to bolt it to the floor for you to be able to use that, but that just removes the whole reason you probably got a flat footed rack. There is also no numbers laser etched like other racks. So I used a white out tape to mark holes. Some people buy those magnets and others just use a paint pen or chalk. I’m pretty happy with this purchase and don’t see the need to upgrade to anything else. I’ll probably end up passing this down to grand kids lol.

Years back, this was one of the racks I almost chose, but I decided I wanted the option to bolt my rack down, which I ended up doing. I ended up bolting my rack down after a couple of years of getting tired of moving it back into place. Never had any problems with a rack of the same size tipping, though.

This rack started off for me as the rouge monster lite squat stand which I subsequently upgraded to the flat foot rack. I have no major criticisms of this rack. It looks great, feels high quality, and serves its purpose well. I have plenty of space to squat inside, the hole spacing for bench is nice, and it is very stable for pull-ups / chin-ups. I don't have any problems with it moving as other have noted, but I do have it on stall mats (maybe I'm not squatting enough). I do want to share a few points of caution. 1) Be aware that all rogue racks tend to be a bit wider than other options - I've run into issues hitting the uprights on walkouts. Being a bit more careful and getting roller J-cups has essentially solved this for me. 2) The flat foot design may limit the use of some accessories and also means it is not expandable to a 6-post or other expanded set up if you desire that in the future.

I had this rack for several years before selling it to make space for my custom 8-post rack from Rep. The RML-390F was sturdy enough for everything I threw at it. The power coating was high quality and I didn't notice any chipping. However, depending on the flooring you have, it may slide around a bit when reracking heavy weights. Additionally, it was just a bit too short to overhead press in for my height (5'11"). I also have to write numbers on the uprights for the holes with sharpie. They could definitely add numbering, even if it's every 5 holes like Rep does with the PR-4000. Additionally, the flat foot design does limit you from adding on later from Rogue's catalogue of rack attachments that require bottom cross-members. If you are looking for just a power rack and you know you won't need to use it for functional trainer capability or don't want to add on weight storage, this rack is great. Otherwise, I'd for a "bolt down" rack (who really needs to bolt those down anyways).

I’ve been using this rack for ~5 years, strong enough to handle anything a lifter can throw at it. The flat feet is a bonus for stability but the pieces holding the feet on the rack make it difficult to attach anything on the very bottom few inches of the rack. Also not quite tall enough to do standing OHP inside the cage.

I’ve been using the RML-390F Flat Foot Monster Lite Rack in my home gym for about 2 years. Even without being bolted down, the flat-foot design keeps it stable during heavy squat and pull-ups, with no noticeable wobble. My rack is positioned on an Olympic size platform and I prefer not having my rack bolted down as I do move it back a foot or 2 to make room for floor to overhead movements. I do have the dialed motion set up on this and if I don’t have the side with weight on a stall mat it will slip. No issues with movement or slipping if I’m on a mat. As always rogue provides a good build quality with clean welds and a durable powder coat. Other brands have significantly improved their quality at a lower price, making this rack a bit lower in overall value for your dollar. An improvement I would like to see is ANY numbering on the uprights. I personally think BOS does it best with their ⅝” rack with numbers. You could write them yourself, use stickers, or magnets, but with rogue holding a slightly more premium perception I’d prefer not to write on my rack. No numbering isn’t the end of the world, but it is a noticeable few second issue that I am reminded of 1-2 times per workout. If you’re going flat foot and don’t need made in the USA, go BOS.
