Double Weight Horn Trolley Front Facing Pulley

This Isn’t Just a Trolley — It’s a Platform

When we first teased this trolley alongside our Hi-Lo Pulley, it was meant to be the “if-you-know-you-know” upgrade — the cable station that glides smoother than most commercial Smith machines without the life-sucking footprint of one.

And yes, it still does all that. But like every Bulletproof invention, this trolley refused to stay in one lane.

Now it’s a standalone powerhouse:

• Compatible with the Hi-Lo Pulley
• Dialed in for Isolator Cam 1:1 setups
• Built for belt squat configurations
• Ready for a growing lineup of future drops

This isn’t just a trolley. This is a platform.

The Smoothest Roll You’ve Ever Felt

Hourglass rollers engineered like we were trying to impress NASA.

If you know our VTS, you know we’re obsessed with movement quality. Same obsession, new playground.

We spent months testing:

• Different durometers
• Multiple polymer blends
• Dozens of prototypes and sample runs

Why? To hit that perfect density that delivers:

• ✔ Silent rolling
• ✔ No rack scarring
• ✔ Zero chatter
• ✔ No plastic grind
• ✔ A gliding sensation users say beats commercial bearing Smith machines

The result? Our famous hourglass rollers — two on the front and two on the back — hugging your upright with horizontal set bolts so you can micro-adjust fitment for that custom, buttery-smooth Bulletproof feel.

Real Pulley. Real Bearings. Real Performance.

No plastic wheels. No bushings. No shortcuts.

Most companies give you a plastic pulley with a bushing and hope you won’t notice. We give you a high-grade machined aluminum pulley loaded with precision bearings.

This means:

• Smoother travel under load
• No heat fade during long sessions
• No wobble or pulley deflection
• No squeaking, no grinding
• A lifespan that embarrasses plastic pulleys

This is the kind of pulley you expect on a commercial machine — not just “another rack attachment.”

Direct-Connect Option

For the zero-ratio ramblers.

If you’re not running a multi-pulley system or ratio, you can bypass the pulley entirely and clip directly into the pulley bolt.

That gives you:

• Pure 1:1 connection
• More stability for belt squats
• Maximum transfer for loading movements
• Cleaner setups for certain cam configurations

Use the pulley when you want it. Direct-connect when you don’t. Freedom is Bulletproof.

Dual 8" Weight Horns

Because 9" or 12" isn’t always enough for people who lift real weight.

Each side features an 8-inch weight horn — giving you 16 inches of total loading capacity.

Perfect for:

• Heavy lat pulldowns
• Low rows
• Tricep work
• Belt squats
• Isolator Cam 1:1 setups
• Future attachments (yes, we’re already testing them)

If you like having room to grow, this trolley gives you more than enough.

The Rhino Stamp of Overbuilding

If you see the Rhino, you know it’s serious.

On the rear plate sits our iconic Rhino badge — a mark of equipment designed to outlast you, your rack, and your bad decisions.

This trolley includes:

• Two hourglass rollers on the front
• Two hourglass rollers on the back
• Machined aluminum pulley with bearings
• Direct-connection bolt option
• Dual 8" weight horns
• Bottom bump-stop pin location
• Rhino icon rear plate
• Horizontal set bolts for perfect upright fitment

No rattles. No slop. No compromises.

Compatibility & Configurations

Not just compatible — practically unstoppable.

• 1️⃣ Hi-Lo Pulley System
  Still its OG pairing. Turns your rack into a smooth, commercial-like adjustable cable station.
• 2️⃣ Isolator Cam Cable Setups
  A perfect match for our cam-based 1:1 configurations — smooth, strong, and shockingly versatile.
• 3️⃣ Belt Squat Setups
  When used with the Hi-Lo, this becomes one of the cleanest belt squat solutions on the market — smooth, stable, and brutally effective.
• 4️⃣ Future Modular Drops
  We design for modularity. Future units are already in testing that pair directly with this trolley.
