STB-98005 Frame construction

The Marcy SteelBody STB-98005 Monster Cage features a heavy-duty construction consisting of 16-gauge rectangular steel bars. The main pillars of the unit are pretty thick, 3″ x 3″ (7.6 x 7.6 cm), offering superior sturdiness. All the main joints of the cage feature reinforcement plates for a secure connection.

It’s also important to mention that the cage’s rear base section is equipped with oblique reinforcement bars, while the two short upright bars at the back also connect to the middle uprights with two extra bars. Therefore, it considerably improves the overall sturdiness of the unit.

Its net weight is approx 295 lbs (134 kg). This weight alone provides excellent stability, continually improving by adding weight plates, dumbbells, or kettlebells to its storage pegs and tray.

All the bars in its construction come coated with a corrosion-resistant and chip-resistant paint finish. In addition, the main upright bars feature a brown finish, while the rest of the bars and accessories are black, these being the only colors available for this power cage.

The fully assembled cage is relatively large. It is approx—74″ (188 cm) deep and 65″ (165 cm) wide. The inside is spacious as well, approx. 62.5″ (159 cm) deep and 42″ (107 cm) wide, so the cage offers plenty of space for the correct execution of all exercises.

The main upright bars feature 15 safety and bar catches; their distance is approximate—5″ (13 cm).

This Marcy power cage is pretty tall. The top chinning bar attached measures approx 95″ (241 cm) in height. Without this bar attached, it is approx—86″ (218 cm). So, either way, it won’t fit in a room with a ceiling height of only seven feet. You will need a ceiling height of at least 8 1/2 feet to execute all the pull-up/chin-up exercises correctly.

Other parts

The Marcy SteelBody STB-98005 Monster Cage includes safety bars with bar catches on their ends, and an additional bar catches set. These are all rated for 500 lbs (~226 kg) load capacity.

The short rear bars of the cage come equipped with two weight plate storage posts each. They have Olympic (2″) sleeves for Olympic plates, but these are removable so that you can store Standard (1″) plates on them as well. Each post holds plates up to 100 lbs (45 kg). The storage tray in-between the two rear bars can also support loads up to 270 lbs (~122 kilograms).

Apart from the cage, which provides a training setting for squats and other exercises, the Marcy SteelBody STB-98005 includes two other workout stations.

One of them is the chinning bar, which is attached to the rear top bar of the cage. It features a multi-grip design with curved lateral grips and parallel grips. However, attaching this bar to the cage is not entirely necessary.

The front upper section of the enclosure features a simple cylindrical bar, which also offers the possibility to perform chin-ups, pull-ups, and variations of these exercises. The chin-up bars have a weight capacity of 350 lbs (~159 kg).

The other attachment or workout station included with the Marcy STB-98005 is the dip station, which consists of two short bars (1.5″ in diameter) with rubberized grips. They attach to any of the 15 positions of the upright bars to execute dip exercises and variations. Like the chinning bar, the dip bars have a weight capacity of 350 lbs (~159 kg).

STB-98005 Accessories

The cage also includes a set of resistance band pegs. These can also be attached to the cage’s base bars and support various resistance bands.

Finally, it is essential to mention that this Marcy power cage does not include any weight plates or barbells. Therefore, you will have to purchase these separately or use the ones you already have. Also, the cage is for Olympic (7′) bars.

STB-98005 Assembly and Maintenance

The Marcy STB-98005 Monster Cage requires complete assembly. Although the task isn’t too complicated, it may take several hours. You will have to put the base together first, add the vertical bars, the reinforcement plates, and bars, close the cage with the top bars, and connect the accessories.

The included manual provides pretty clear assembly instructions and schematics. Tools for assembly do not come included, though. Therefore, you will need an adjustable wrench, an Allen wrench, and a rubber mallet.

Once assembled, maintenance doesn’t require much. Thus, all you need to do is periodically inspect the joints and bolts to re-tighten them if it’s the case or replaces any potential broken parts. It’s also important to mention that this cage is for indoor use only.

  1. Hello there! I have always wanted these types of training equipment. I like how versatile this equipment is and how many exercises you can perform with it. Unfortunately, it is expensive for me, and I also do not have the space to put it together. Perhaps when I find a more steady income (and have my room), I’ll get this product. Thanks for sharing this.

  2. Thanks for introducing this monster cage to me.

    I had considered buying one of these before but was scared that the ‘home’ ones would not be of great quality and would not stand up to much use.  But from your review, this one looks like one that is worth considering.

    I like that it is so versatile that I can use it for many different types of exercise, as I must admit that I do get bored easily.

    You have covered the details well, and it is great to see that you only found a couple of faults which are quite minor.

  3. This cage is very sturdy and looks very durable with an impressive spec. I used a cage at a local gym before, but it didn’t have such features as this one. It’s a good product and also very affordable. I’d love to have this in my home gym., and I’d recommend this surely for anyone.

  4. Hey Robert,

    I always wanted a home gym, and now that I have the space for one, I was looking for what equipment to add to it. Unfortunately, I was not too sure what to add until I ran into this post and saw this beauty. I already have multiple bars and weight sets that would fit perfectly on this bad boy, and this will undoubtedly take my workouts to the next level with all the combination exercises possible. So again, I appreciate the info and site. Thank you.
