The Isolator Side Port Weight Arm is the evolution of Bulletproof's original Isolator design, engineered to unlock faster superset transitions, adjustable resistance curves, and counterweight capability—without compromising the safety controls that define the system.
This upgrade allows you to mount the weight arm outside the upright instead of inline, giving you freedom of movement while maintaining precise control through the rubber-coated perch pin system. Whether you're running supersets between leg extensions and curls, adding counterweight assistance, or fine-tuning resistance for rehab work, this arm transforms training efficiency and accessibility.
True Superset Flow
Move the weight arm left to right without reset or repositioning. Transition seamlessly from one movement to the next with zero downtime.
Adjustable Starting Resistance
Use the perch pin to set the arm at different heights, changing starting tension and the resistance curve for better contractions and less joint stress.
Counterweight Ready
The added top port lets you run a counterweight or Crossbow Cam, scaling resistance for rehab, beginners, or training partners of different strength levels.
Simple Installation
Removes the existing outside hex port and replaces it with the Side Port version. No complex setup required.
Safety engineered first. Convenience added after real-world feedback and proven engineering solutions.
- Outside Mounting: Moves the weight arm from inline to the outside of the upright for faster transitions and better superset flow without repositioning or reset time.
- Rubber-Coated Perch Pin System: Position-controlled starting resistance that lets you set the arm at multiple heights, adjust starting tension, and manipulate the resistance curve to match your movement pattern.
- Dual Port Configuration: Includes a top port for counterweight or Crossbow Cam compatibility, enabling fine-tuned resistance scaling for rehab work, beginner progressions, and training partners of different strength levels.
- Freely Swinging or Locked Positioning: Choose between allowing the arm to swing freely left to right or locking in controlled starting points based on your training needs.
- Drop-In Upgrade: Replaces the existing outside hex port without requiring complex installation or modifications to the Isolator frame.
The Isolator Side Port Weight Arm is designed as a direct upgrade to the original Isolator system and replaces the existing outside hex port.
- Works with: Bulletproof Isolator frame
- Replaces: Original outside hex port on the Isolator upright
- Compatible with: Counterweight systems, Crossbow Cam, rubber-coated perch pin
- Does NOT fit: Other brands or equipment outside the Isolator ecosystem
This is a direct replacement for the Isolator's existing outside hex port. It is not compatible with non-Isolator equipment. Installation requires removing your current outside hex port and replacing it with the Side Port version.
- Material: Steel construction with rubber-coated perch pin
- Port Compatibility: Fits Isolator outside hex port and includes dual port configuration (bottom and top)
- Installation Type: Direct replacement—no frame modifications needed
This side port system maintains the structural integrity and safety controls that define the Isolator while adding mounting flexibility and resistance customization capabilities.

Is the Side Port Weight Arm a direct replacement, or do I need modifications?
It's a direct replacement. Simply remove your existing outside hex port and replace it with the Side Port version. No frame modifications or complex installation required.
Can I use the arm in a fixed position or does it have to swing freely?
You have complete control. Use the rubber-coated perch pin to lock the arm at a specific height for controlled starting resistance, or let it swing freely left to right. Switch between modes based on your training needs.
What's the benefit of the dual port configuration?
The bottom port holds the weight arm itself. The top port enables counterweight or Crossbow Cam compatibility, letting you fine-tune resistance curves for rehab work, beginner progressions, or accommodating training partners of different strength levels.
How does the side port improve superset efficiency?
By mounting the weight arm outside the upright instead of inline, you can move it freely left to right without resetting or repositioning the equipment. This eliminates transition time between movements like leg extension and leg curl, or preacher curl and tricep extension.
Is this upgrade safe compared to the original inline arm?
Yes. While the original design prioritized safety with a rubber bumper and inline alignment, the Side Port system maintains that safety philosophy with the perch pin system providing position control. You get convenience without sacrificing control—it's engineered for both freedom and stability.
