Comparing the PR1 Rack and PR2 Rack with the Frankenstein Series Racks by Iron Bull Strength
PR1 vs PR2 vs Frankenstein Series: Choosing the Best Power Rack for Your Training
Choosing a power rack can feel like a lot, specs, attachments, hole sizes, and future upgrades. Think of this as a quick walk-through with a helpful store associate. We’ll compare our PR1 and PR2 racks to the Frankenstein Series so you can pick the right foundation for your home gym. If you’re still building your setup, you can also explore complementary gear like our home gym equipment and free weighs to round out your space.
Pinholes and Spacing
The PR1 and PR2 use standard 5/8" pinholes—the industry sweet spot for strength, safety, and a wide attachment ecosystem. The Frankenstein Series introduces our patented Snowman hole pattern, combining 1" and 5/8" holes on the same upright. That hybrid layout gives you finer adjustability for J-hooks, safeties, and accessories, making your setup feel as dialed-in as a commercial gym squat rack.
In practical terms, more hole options mean less compromise. You can set your bench height precisely for heavy presses, then move straight into squats without guessing your ideal bar position. It’s quick, consistent, and confidence-inspiring when the weights get serious.
Attachment Compatibility
Good news: all of our 5/8" attachments fit both the PR series and the Frankenstein Series. If you’re upgrading over time—adding dip handles, a landmine, storage posts for plates, or even integrating a selectorized or cable setup—your investment carries forward. If multifunction training is on your wish list, check out our functional trainer options that pair seamlessly with your rack plan.
The bottom line is flexibility. Start simple, then expand when you’re ready. Whether you’re building a compact corner gym or a full training room, both rack families give you the same compatibility and growth path.
Laser-Cut Numbers
The PR1 and PR2 feature laser-cut numbering on the uprights for fast, repeatable J-hook and safety positioning. The Frankenstein Series goes a step further with laser-cut numbers on both uprights and crossmembers. That extra indexing saves time during supersets—like moving from presses on your weight bench to heavy squats with your favorite barbells—and keeps training smooth when multiple lifters share the rack.
How to Pick a Power Rack
If you want a straightforward, high-quality frame that’s ready for day-one training and long-term growth, PR1 and PR2 are excellent choices. They deliver the essentials you need for safe, progressive lifting and integrate with our full ecosystem of 5/8" attachments. If you prefer maximum precision and a pro-gym feel at home, the Frankenstein Series’ Snowman hole pattern offers next-level adjustability without sacrificing strength or compatibility.
Think beyond the rack, too. A complete training space often includes organized storage like a dedicated dumbbell rack, plus well-balanced dumbbells and durable weight plates. For compound lifts and heavy singles, many lifters also pair their rack with supportive gear from our belt lineup—whether that’s a classic lifting belt, a 10mm lever belt, or anything from our weight belt collection—to brace harder and lift safer.
