The ISOLATOR Bottom Guide Pulley Bracket is a precision cable guidance system designed for bottom-fed Isolator Cam setups. It keeps your cable perfectly tangential to the cam rim, eliminating angle drift that causes light starts and uneven resistance — delivering instant tension, stable feel, and consistent load throughout your full range of motion.
This bracket mounts directly to the existing bolts connecting the front and rear carriage of your Isolator, positioning two pulleys below the cam to guide bottom-incoming cables along the correct path every time. It's ideal for leg extensions, leg curls, preacher curls, reverse hypers, and other lower-path movements where bottom-mounted cable sources are preferred.
Locked Alignment
Cable path stays tangent to the cam curve for uniform loading and smooth resistance matching your natural strength curve.
Instant Tension
Engages resistance from rep one with no slack or lag, delivering immediate and consistent load engagement.
Clean Install
Uses existing Isolator hardware with no modifications needed — mounts directly to carriage bolts for a compact, clean fit.
Self-Guiding Design
Can help smooth slight misalignment by gently nudging the cable back into line for optimal tracking.
Functionally identical to the top bracket but optimized for bottom-fed systems to maintain smooth, even resistance throughout your workout.
- Dual Pulley Guidance System: Two pulleys positioned below the cam guide bottom-incoming cables perfectly along the correct path, maintaining tangential alignment for uniform loading and smooth resistance.
- Direct Carriage Mount: Attaches directly to existing bolts connecting the front and rear carriage of your Isolator with no modifications required, ensuring a secure and clean installation.
- Self-Aligning Contact: The bracket's design helps smooth slight misalignment by gently nudging cables back into the correct line, though it cannot correct severely misaligned cable sources.
This bracket is specifically designed for bottom-fed cable systems on the Bulletproof Isolator Cam, and works with multiple cable source options.
- Works with: Bulletproof Isolator Cam (required)
- Also works with: VTS (Versa Trolley System), Dedicated Weight Trolley, any bottom-mounted cable source including Beyond Power Voltra (DIY alignment required)
- Does NOT fit: Top-mounted cable systems or non-Isolator Cam setups
Compatibility note: This bracket requires proper tangential alignment of your cable source. If the cable source is severely misaligned, the bracket cannot correct it and will not function as intended. Cable source, cam, and trolleys are sold separately.
- Pulley Count: Two pulleys
- Mount Type: Direct carriage bolt attachment (no modifications)
- Structural Warranty: One (1) year against defects in materials and workmanship from original purchaser
- Price: $69.99 USD
- Availability: Presale ending 11/24/25; standard orders subject to inventory and potential price changes due to tariff fluctuations
This bracket is a precision accessory designed for the Isolator Cam system. Proper installation and alignment with your cable source ensures optimal performance and consistent resistance throughout your full range of motion.
What does the Bottom Guide Pulley Bracket actually do?
It keeps your cable perfectly tangential to the rim of your Isolator Cam when the cable comes from below. This eliminates angle drift that causes light starts and uneven resistance, delivering instant tension and consistent load throughout your full range of motion.
What equipment do I need to use this bracket?
You absolutely need the Bulletproof Isolator Cam. The bracket mounts directly to the carriage bolts of the Isolator. You'll also need a bottom-mounted cable source, such as the VTS, a Dedicated Weight Trolley, or another compatible system. Cable source and cam are sold separately.
Can this bracket fix a misaligned cable source?
The bracket has a self-guiding design that can help smooth slight misalignment by gently nudging the cable back into line. However, if your cable source is severely misaligned and not tangential to the cam, the bracket cannot correct it and will not work as intended. Proper setup alignment is essential.
Is installation difficult, or do I need special tools?
Installation is clean and straightforward — the bracket uses your existing Isolator hardware and mounts directly to the bolts connecting the front and rear carriage. No modifications or special tools are required.
Will this bracket wear out my cable faster?
The extra guiding contact that helps smooth alignment can increase cable wear over time. Regular cable inspection and maintenance are recommended to ensure longevity in high-use setups.
