Monster J-Cup Pairs
Black

Rogue offers three types of J-Cups for use with your Monster Series rack or rig. You can compare the options below and select your preference and quantity from the order menu on this page. All J-Cups are sold in pairs.

Monster Standard J-Cups: 3” width, 7-¾” height, ⅜” plate steel, 15 LB Laser cut and precision bent, with UHMW plastic on the face to protect the knurling on your bar and UHMW plastic on the back to protect the rack from chipping.

Monster Sandwich J-Cups: 1.5” width, 10” height, ⅜” plate steel, 18 LB UHMW plastic core offers full protection against your barbell knurling. It also has UHMW plastic on the backside to protect the rack from chipping.

Monster 2” Sandwich J-Cups: 2” width, 10” height, ⅜” plate steel, 20 LB The side plates fit into a recessed, machined plastic core (2" wide) to prevent metal-to-metal contact. The hardware (that connects the plastic to the side plates) is also recessed, preventing the bar or a user’s hand from scraping against them. Welds are insides the side plates for a clean edge, and UHMW plastic is featured on the clasp and back plate to prevent damage to the uprights. A thin piece of rubber on the side of the clasp also softens contact between the clasp and upright when the J-Cup is swung into place.

Meticulously made Monster Standard J-Cup
Stout (3/8" steel). Height is optimum. Back of J-Cup is closer to reach (than sandwich style) when racking bar after a bench press, The desire of protecting the knurl possibly is overshadowing a more important consideration: putting undo stress on the shoulders by traveling a greater distance. Suggestions regarding the UHMW protective plastic. The back piece which measures 2 1/2" width and 4" length could be increased to 3" width (same width as rack). Otherwise, there's a lip which can bump the rack when swiveling on the hefty J-Cup. Also, a protected UHMW plastic piece could be added to the inside of the angled lip portion on the front of the J-Cup or simply extend present coverage with a one- piece mold solution. Lastly, there is a difference when a product like this one, or any other, is made in the USA.

1’ Sandwich cups
Buy the sandwich 1’ cups. The 2’ are a little wide snd thr tegulsr J-cups can damage your bar if you’re not careful.

Convenient to have Multiples
I bought my third pair to make life easier when dealing my bars. My squat bar is the biggest pain to store. These Monster J Cups solve the issue.

Good Jcups that do what they're intended to
These came with my FM-6 Twin functional trainer. They smoothly slide into place. They do have a small gap between the pillars (nearly all J cups will unless you custom shim them). Oddly enough my barbell rolls back into the rack even though they slop away from the rack. All in all they do what they're supposed to. They're heavy duty and as normal run of the mill jcups go, barbells glide left to right with minimal effort even when loaded with over 400lbs

Perfect J-cups
The 2" Sandwich J-cups are incredibly robust and will protect your bars and your rack. 10/10 would recommend.

Tight fit
The fit is tight, and I wouldn't want to move them regularly. My rig is from 2014, if that matters. I'm using these for my squat bar, so it will be fixed. But I'm glad they are tight, no movement. My original j-cups are very loose.
