The Lock-N-Float Curl/Dip Attachment is a modular add-on designed for the Bulletproof Isolator platform. It combines preacher curls and dips into one attachment, letting you expand your station without adding another standalone machine to your gym.
Built with the Bulletproof philosophy—rigid where it matters, modular where it counts—this attachment mounts directly to the Lock-N-Float Lever Arm and delivers machine-like stability with adjustable leverage options to match your training goals.
One Attachment, Two Movements
Preacher curls and dips in a single, modular unit. Removable knurled dip bars keep transitions fast and your setup clean.
3-Position Adjustable Width
Narrow, medium, and wide positions alter leverage and stimulus on purpose—perfect for strict reps, tempo work, and mechanical drop sets.
Clean, attachment-ready expansion that turns your Isolator into a serious upper-body station without clutter or compromise.
- 3-Position Adjustable Width: Switch between narrow, medium, and wide positions to change leverage, intensity of peak contraction, and elbow loading without needing separate stations. Ideal for mechanical drop sets and varied rep ranges.
- Knurled Grip Handles: Curl handles are 30mm diameter and dip handles are 38mm diameter, both knurled for secure, consistent hand contact under load. Removable dip bars ensure fast transitions and a clean setup.
- Modular, Rigid Design: Mounts directly to the Lock-N-Float Lever Arm on the Isolator. Machine-like rigidity and confidence-inspiring feel under load, with T Flat Palm Grip compatibility for future expansion.
- Lever-Arm Leverage Control: Handle orientation affects felt resistance. Shorter handle positioning increases felt load; longer positioning requires more counterweight. Pair with the Adjustable Weight Arm for full resistance control.
This attachment is purpose-built for the Bulletproof Isolator ecosystem and requires the Lock-N-Float Lever Arm to function.
- Works with: Bulletproof Isolator + Lock-N-Float Lever Arm
- Optional add-ons: Leg Pads (sold separately), Adjustable Weight Arm (for extended handle positioning), T Flat Palm Grips
- Does NOT work with: Standalone use without Lock-N-Float Lever Arm; other brands' lever arms or equipment
Important: Handle orientation directly impacts felt resistance on a lever system. If you prefer longer handle positioning, the Adjustable Weight Arm is recommended to ensure adequate counterweight and consistent challenge.
- Curl Handle Diameter: 30mm knurled
- Dip Handle Diameter: 38mm knurled
- Width Positions: 3 (Narrow / Medium / Wide)
- Included Components: 3-position adjustable width preacher curl handles, knurled curl handles, removable knurled dip bars, T Flat Palm Grips
- Mount Type: Plugs into Lock-N-Float Lever Arm on Bulletproof Isolator
- Structural Warranty: 1 year against defects in materials and workmanship from normal use (non-transferable)
- Wear Guards / Upholstery Warranty: 90 days against defects in materials and workmanship from normal use (non-transferable)
- Manufacturing: Made in China
This is a modular attachment—not a standalone machine. Handle positioning on the lever directly affects felt resistance; leverage can be adjusted through handle orientation and counterweight configuration.
Do I need anything else to use this attachment?
Yes. This is an add-on attachment, not a standalone machine. You need a Bulletproof Isolator and the Lock-N-Float Lever Arm (base). Once you have both, this Curl/Dip Attachment plugs directly into the lever arm. If you already own the Lock-N-Float Lever Arm from a previous purchase, you can buy just this attachment—no need to re-buy the base.
What's the difference between the three width positions?
Narrow position delivers tighter movement path with intense peak contraction. Medium is balanced and ideal for all-around working sets. Wide position alters leverage and changes how your elbow and arm load, making it excellent for mechanical drop sets (wide → medium → narrow) and exploring different stimulus on the same movement.
Will dips feel as challenging as on a standalone dip machine?
The felt resistance depends on handle orientation and lever mechanics. Shorter handle positioning creates more felt load; longer handle positioning mechanically advantages the handles and may reduce felt resistance even with weight loaded. If you prefer longer handle positions for comfort or range of motion, pair this attachment with the Adjustable Weight Arm to add sufficient counterweight and ensure consistent challenge.
Are the dip bars removable?
Yes. The knurled dip bars are removable, allowing fast transitions between curl and dip work. When you're doing curls, you remove the dip bars for a clean setup. This modular design keeps your station compact and your workflow efficient.
What warranty does this product have?
The structural components are covered by a 1-year warranty against defects in materials and workmanship from normal use (non-transferable). Wear guards and upholstery are covered for 90 days. These warranties are subject to normal use conditions and exclusions as stated in the full warranty policy.
Is there a presale for this product?
Yes. This product is available on a two-week presale window (ending 1/15/26). Orders placed during presale are guaranteed inclusion in the next production run and protect you from potential price increases due to tariff changes. After presale ends, inventory is limited and availability is not guaranteed.
