Now, let’s get down to basics. 

J-cups (power rack attachments) are a fundamental part of any rack.πŸ™Β They hold our weights, protect our equipment, and, most importantly, safeguard us during our lifts.Β 

Over the years, Rack J-cups have evolved, ranging from basic bare steel to more sophisticated designs like Roller design. 

πŸ‘‰ Today, I’m excited to talk about what I believe is a game-changer – the Nylon Roller J Cups.

Bullrock fitness Rack J Cups Overview:

J-cups play a crucial role in the functionality and safety of your rack. They’ve come a long way, incorporating features like thick UHMW, rounded back corners, and various attachment methods. 

But one of the revolutionary improvements has been the introduction of rollers inside J cups. 😁

These rollers are a game-changer for lifters who’ve experienced the frustration of re-centring a bar with an aggressively knurled surface.

Let’s face it; dragging a bar across traditional J-cups can be a pain. It damages your equipment, fills up the knurl with UHMW, and overall creates a frustrating experience.Β 

Rollers aim to make this process smoother, but they also come with their set of challenges – too much roll can make the bar hard to control. πŸ™„

Roller Control:

The roller on the Bullrock Fitness – Gorilla Nylon Roller J-cup is designed with a downward angle, creating a cradle for the bar. 

Imagine the mechanism of a basketball retrieval system under a hoop – it shoots the ball back to you. This design minimizes lateral movement and frustration while re-centering the bar.Β 

The roller is available in nylon material only, which is a great choice for most home gyms.

Buffalo Block – A Game-Changing Feature:

But what really makes the Bullrock Fitness – Gorilla Nylon Roller J Cups shine is the addition of the Duffalo Block. 

If you own a Buffalo bar, you know the struggle of re-racking it without it flipping or damaging your J-cups. (The Duffalo Block is a genius solution.πŸš€)

The machined block can sit flat or rotate outward 15 degrees, creating a cradle for your Buffalo bar. It keeps the J-cup flush against the upright, preventing any flipping or damage.Β 

The block also includes a C-channel to maintain the bar in a perfectly vertical position, ensuring a smooth re-rack every time.

Other Features:

βœ… Other notable features include UHMW on all touchpoints, creating an excellent fit and reducing play. πŸ˜…

The flush mount bolt allows for easy swapping between rollers and blocks. As for fitment, Bullrock Fitness Roller J Cups are designed for 3×3 uprights only, but they don’t offer an adapter for 2×3 racks. 

So these roller J cups don’t cover most rack sizes but are compatible with gorilla racks, squat stands, and rigs offered by Bullrock.πŸ‘

Will They Fit My Rack?

πŸ‘‰ If you’re wondering if these J-cups will fit your rack, the odds are yes, unless you have an odd tube size. 

Custom machining is not available for odd sizes.

      Nylon Rollers glide the barbell to the centre effectively.
      Be safe & train tension-free.

Minimized Wear on Barbell Knurling:

  1. Roller J-Cups: The rollers (with nylon) provide a gentle surface for the barbell, minimizing wear on the knurling. This is particularly beneficial for preserving the integrity of the barbell over time.
  2. Sandwich J-Cups: Without the roller feature, standard J-cups may subject the barbell to more friction, if it is not using UHMW. So metal-to-plastic or metal-to-metal contact can cause more wear & tear. 

Enhanced Adjustability:

  1. Roller J-Cups: Rollers allow for quick and easy adjustments to the barbell’s position, enhancing the overall efficiency of workouts.
  2. Sandwich J-Cups: Traditional J-cups may require more effort to reposition the barbell due to increased friction.

Versatility in Barbell Types:

  1. Roller J-Cups: The design of roller J-cups often accommodates various barbell types and sizes. This adaptability is especially advantageous for users incorporating different bars into their routines.
  2. Sandwich J-Cups: While accommodating standard barbells, traditional J-cups may be less versatile when it comes to specialized bars. πŸ‘

πŸ§’ Overall, roller J-cups are a great option if you are looking for a J-cup that is easy to use, protects your barbell, and makes your workouts more efficient.

βœ”οΈ It is important to note: Roller j-cups may not be suitable for all lifters or all exercises. For example, if you are lifting very heavy weights, you may want to choose a J-cup that is more secure, such as a sandwich J-cup with a UHMW liner. Additionally, some lifters prefer the feel of a more stable J-cup, such as a standard sandwich J-cup. 

Things to consider before buying roller j-cups

❌ Not all roller j-cups are created equal. Here are a few things to consider before you buy:

Type of nylon lining:

Some roller j-cups have a thin nylon lining, while others have a thicker, more durable lining. The thicker lining will provide better protection for your barbell.

(With Bullrock Fitness this isn’t a problem. πŸ§’) 

Weight capacity:

Make sure the roller J-cups you choose have a weight capacity that is high enough for your needs.

(Bullrock Fitness J cups can hold easily 800 kgs + of load.)


Not all roller j-cups will fit all power racks. Make sure to measure the uprights of your rack and choose roller j-cups that are compatible. It should be 3 by 3 in size.

Nylon Vs UHMW J cup – Which is the best material?

For j-cups, safety and effectiveness should be top priorities. So here’s a breakdown of which material works best. 😁

1. Nylon:

  • βœ”οΈ Pros: Smooth & quiet, protects the bar from scratches, affordable, wide compatibility with bar diameters.
  • ❌ Cons: Not as durable as other materials under heavy loads, may wear over time, less grip for certain exercises.

2. UHMW (Ultra-high-molecular-weight polyethylene):

  • ❌ Cons: Noisier than nylon, slightly more expensive.
