Rogue RM-4 Monster Rack 2.0

The Rogue RM-4 Monster Rack 2.0 is Rogue’s highest-end 4-post rack. This rack is constructed with 3×3 11-gauge steel with 1″ hardware and 2″ spacing. It’s compatible with Rogue’s Monster attachments as well as some attachments from other companies.

It’s fully modular with a 4-way hole design (keyholes on the side) and there are a large number of accessories that can be added.

The Monster line is the most future-proof rack offering from Rogue. It continues to evolve/improve and Rogue has shown they’re committed to growing this line.

If you’re looking for a larger rack, the RM-6 from Rogue is built the same as the RM-4 but with an added section for plate storage.

Features & Highlights

  • Steel Size – The RM-4 rack from Rogue is a part of their Monster lineup. It’s constructed with 3×3 11-gauge steel and it’s easily assembled with a bolt-together design. 3×3 steel is becoming increasingly popular for its strength, attachment compatibility, and its overall aesthetic.
  • 4-Post Design – As a 4-post rack, you’ll save some space compared to a 6-post rack. There are two other differences worth considering: plate storage and stability. On a 4-post rack, while you can store plates on the back upright, you may find that the plates can interfere with your setup when lifting inside the rack. This is particularly true on the bench press. The workaround is to bench press from the inside of the opposite upright. In terms of stability, this rack will need to be bolted into the ground or onto a platform unless you buy the optional stabilizer. The stabilizer attaches to the bottom of the back crossmembers. Even still, if you’re lifting heavy on the outside of the front uprights or if you’re doing heavy pull-ups, bolting down is recommended (not required).
  • Hole/Hardware Sizing – This rack uses 1″ hardware, which is also increasing in popularity. 1″ hardware racks tend to get the best, most refined attachments. The rack will accommodate all of Rogue’s Monster Attachments/Accessories as well as some from other companies (read more in the compatibility section below).
  • Hole Spacing – The RM-4 differs from the RML-490C/490 in two primary ways. Firstly, the Monster line includes 2″ hole spacing from top to bottom. The Monster Lite racks offer Westside spacing through the bench zone and 2″ spacing above and below. Secondly, the Monster line includes the same number of side holes and front/back holes. The Monster Lite racks have fewer side holes. The Monster line also uses a key-hole design on the sides, which creates additional attachment compatibility.
  • Exterior Rack Dimensions – This rack is the second-to-largest in the Monster Lite family with a total length of 53″ and a total width of 53″ (includes footplates). In terms of the uprights themselves, the dimensions are 49″ deep and 49″ wide. A 49″ width is fairly common for 3×3 racks, but one of the downsides is you have less room between the uprights and the plates. This requires a more efficient walk-out/re-rack since there’s a greater risk of hitting the uprights with your plates. Some racks from REP and Sorinex, for example, have 47″ wide racks which provide more space to work with. The uprights stand 90″ tall, but with the footplates, the total height is slightly higher at 90 3/8.”
  • Interior Rack Dimensions – The interior lifting area measures 43″ deep, which is more than enough room to lift comfortably. This is the same depth as the 6-post RM-6 from Rogue. The main difference between the two is the missing storage section.
  • Safety Options – This rack includes pin & pipe safeties as standard, which are common. This safety system is the most cumbersome to set up and it has a powder-coated exterior. I strongly recommend that if you buy a Monster rack that you upgrade to either the Monster safety straps or the Monster flip-down safeties. Both are easier to use and they protect your barbells much better. They also offer safety spotter arms with UHMW for the front of your rack, which I also really like since some people (like myself) enjoy lifting outside of their racks.
  • Laser Cut Hole Numbers – The Monster line includes laser cut numbers on every hole, which is a great feature for easy adjustments on J-cups, safeties, etc… It’s also much more aesthetic than non-numbered uprights, in my opinion.
  • Multiple Color Options – A great benefit of the RM-4, and the Monster line in general, is that it comes in a variety of colors. There are currently 12 color choices to choose from including Rogue Red, Bright Blue, Bright Green, Cerakote (upcharge), Stainless Steel (BIG upcharge), etc… Rogue offers black zinc hardware as standard with the RM-4, although you can pay a slight premium for bright zinc.
  • Made in America – The Rogue RM-4 is made in Ohio.

What’s Included in the Box

The Rogue RM-4 Monster Rack includes several notable attachments as standard:

  • (2) Monster Standard J-Cups with UHMW Lining – You can Upgrade to the Sandwich Cups or the 2″ Sandwich cups on the product page. I recommend at least the Sandwich Cups.
  • (2) Pin & Pipe Safeties – You can Upgrade to the Flip-Down Safeties or the Safety Straps on the product page. I recommend at least one of the two.
  • (4) Band Pegs
  • (1) 43″ Single Skinny Pull-Up Bar OR (1) 43″ Single Fat Pull-Up Bar for front option. You can Upgrade to the Socket Pull-Up Bar, the Fat/Skinny Pull-Up Bar, or the Socket Curl Pull-Up Bar.
  • (1) Fat/Skinny Pull-Up Bar for Back Option. You can upgrade to the Monster Beam or the Rogue Nameplate crossmember. Both look nice and add extra attachment compatibility via side holes.
  • (4) 43″ Crossmembers with Side Holes and Top/Bottom holes for Slinger Compatibility
  • (4) 90″, 100″, or 108″ Uprights with Side Holes

Attachment Compatibility

The RM-4 Monster Rack is constructed with 3×3 steel and 1″ hardware, which is compatible with Rogue’s Monster Attachments.

Here you can add additional accessories to your rack or you can upgrade the ones that come standard with the RM-4 (as above). In general, the Monster accessories are the best that Rogue offers

Some attachments that I think are worthy of considering include the Rogue Monster Matador, the Rogue Monster Landmine, the Adjustable Monolift, the Monster Sandwich J-Cups, and either the Safety Straps or the Flip-Downs. I also think the LT-1 50 Call Trolley/Lever Arms are a great attachment for the RM-6 given their versatility.

The Matador allows for a portable dip station, the monolift eliminates the squat walk-out and makes bench setup MUCH easier, and the landmines open up a ton of barbell movement versatility. The sandwich cups are a big improvement over the standard J-cups, and the safety straps/flip-downs are a BIG improvement over the pin & pipes.

As for attachment compatibility outside of Rogue Fitness, notable places to look are REP Fitness, SorinexTitan Fitness, Fray Fitness, Griffin Fitness, and Fringe Sport. Each of these companies offers attachments that will fit 3×3 and 1″ hardware (REP PR-5000, Various Sorinex, Titan Series, Fray Savage, Griffin GR3, Fringe 3×3). One thing to keep in mind is that imported racks use the metric system vs. the imperial system on USA-made racks (Rogue and Sorinex). This means that hole spacing will be slightly shorter. If you find an attachment that has two pins (or a single pin with a second hitch pin) then it may not fit properly. Single-pin attachments tend to work fine.

Another thing to consider is that REP, Sorinex, Fray, and Griffin use 47″ wide racks vs. 49″, so any attachment that spans the width of their racks will not fit the Rogue racks without modification.

What They’re Saying at Rogue Fitness

The Rogue RM-4 Monster Rack 2.0 receives outstanding feedback from users. With an average rating of 4.9/5, here are some of the things people have said at


  • “Rogue makes the best home gym equipment. Super heavy duty and looks great. I put over 700 pounds on it with no problem. If you’re on the fence between a Monster Lite or a Monster Rack this one is worth the extra money. I highly recommend the the RM-4 Monster rack for any home gym. I LOVE MINE!”
  • “Quality is excellent. No flaws in any of the coating which was a huge positive. Went with the gun metal rack, if I had to do it again…I’d probably go with satin clear. But I can make the gun metal look amazing with customizing other pieces to compliment it. I thought it’d be darker tbh. Rack barely moves. Very sturdy. not bolted to the ground. It’s def the best you can get, IMO. So many attachments, my word to you, go with the rm6 of the bat. You will pay more to upgrade it to the 6 post if not (like I’m doing now) all in all. You’ll need the 6 post if you have plans for all the attachments you can get. It’s only 24 inches longer as well regarding the footprint. Not a big deal at all. I’d also go with 2 extra top crossmembers to go across the front of the rack and the rear…move your pull up bar inside the rack where you please. The wait was the worse, but def worth it once received.”
  • “Upgraded from an HR2, love the full rack and potential for utilizing monster attachments compared to the RML versions. Extremely well built, numbered posts are a huge bonus. Went with the infinity straps and 2nd tier sandwich cups! Loving every day in the rack!”
  • “Ordered everything in last two months. This is the heart of my home gym. Everything came packaged nicely without flaws. It’s rare to do business with a company that has such a superior product. If you are thinking about buying this rack, don’t think too hard. Thanks Rogue! Keep up the fantastic work and craftsmanship!”
  • “I ordered this rack on a Tuesday, it shipped Friday and I received everything the following week which was awesome. The satin clear color is beautiful and I’m very happy with the choice, highly recommended. I love how overbuild the rack is and know the rack will exceed expectations for years to come. “
  • “This is the centerpiece to my basement gym and I live the flexibility to do nearly everything with this rack. Money well spent on something that will out live me. Even my boys 8 and 11 are intrigued and starting to do workouts with it….gym class in quarantine. If you have the space get this rack, you won’t regret it”


  • “Some of the holes did not having the cut metal popped out. Had to hammer them out myself to get the clamps in and unfortunately these holes are missing the paint matching the rest of the rack.”
