Bulletproof’s handle catalog is one of the easiest parts of the ecosystem to misunderstand. Several products are called “handles.” That does not mean they share the same interface.
I own the 360 Bearing Handles and 3D Handles. The compatibility statements below are checked against Bulletproof’s current product pages rather than inferred from appearance. The safest rule is simple: do not buy a Bulletproof handle until you know exactly which interface your equipment uses.
The current ecosystem includes direct VTS barbell-latch handles, Hexport handles, dual-small-hex handles, VTS telescopic-tube systems, and articulated handle assemblies. Those are not interchangeable by default.
Quick Matrix
| Handle | Main interface | Current documented host |
|---|---|---|
| ISO Handles Attachment | Full-VTS barbell latch | Full VTS only |
| Hexport ISO Handles | VTS hexports | VTS equipment with hexports |
| 360 Bearing Handles | VTS telescopic system | Primarily VTS |
| 3D Handles | Adjustable articulated interface | ISO Arms and VTS |
| Adjustable Handles | Dual small hex | ISO Arms; VTS with different behavior |
| Row Handles | Dual hex posts | ISO Arms and VTS |
| Swivel Handles | VTS barbell latch | VTS |

ISO Handles Attachment: The Simple Full-VTS Option
The ISO Handles Attachment is the cleanest example of why interface matters. Bulletproof currently says these handles insert directly into the full VTS barbell latch. The manufacturer also explicitly says they do not work with VTS Lite, VTS Lite HOME, or non-BYOB versions.
That is unusually clear compatibility language. If you own full VTS and want independent left/right handle movement without another complex adapter system, these are the straightforward path. Bulletproof currently lists a 28.5mm handle diameter and a direct barbell-latch attachment method that swaps in for the existing barbell with no additional hardware.
The key point is that these are not generic handles — they depend on the full VTS’s iso-lateral capability and will not function on a system lacking it.
See the current ISO Handles Attachment (Pair) product page.
Hexport ISO Handles: Same Goal, Different Mount
Hexport ISO Handles solve a similar training problem through a different interface. Bulletproof currently says they insert into the hexports on the back of VTS equipment using a fixed male/female fit that eliminates side-to-side play and hook drift. They cannot be mounted to barbell-latch systems.
The Hexport version uses sealed bearings for smooth rotation under load, with a built-in anti-over-rotation safety stop and hard-mounted hook alignment. If your VTS is set up around hexports rather than the latch, this is the relevant family — and “ISO Handle” by itself is not enough information, since barbell-latch and Hexport versions are not interchangeable.

See the current Hexport ISO Handles (Pair) product page.
360 Bearing Handles: VTS Telescopic System
The 360 Bearing Handles are a more specialized VTS handle: an industrial bearing core, a dual-mode system that switches between locked fixed angles (neutral, pronated, supinated) and unrestricted free-spinning rotation, and a telescopic tube with a hand-tightening knob for grip-width adjustment. The external hook stays stationary during tool changes, so you don’t have to re-latch. Bulletproof says the tube lets you slide the bearing handles, “ISO handles,” or the Feather Bar in and out without unlatching the barbell — the page doesn’t say which ISO Handle version, so confirm before assuming the direct-latch ISO Handles Attachment works this way.
The critical compatibility point is that Bulletproof currently designs these primarily for VTS — Bulletproof says adapters for other Bulletproof products are “coming soon,” with no release date given. Do not assume they plug into other Bulletproof equipment just because it’s the same brand, and don’t use the 360 system as a template for how 3D Handles connect — they are different systems.
See the current 360 Bearing Handles (Pair) product page.
3D Handles: Articulation and Width Adjustment
Bulletproof currently says the 3D Handles are designed for ISO Arms and VTS integration, with adapters for traditional jammer arms and other platforms still in development. They feature two independent articulation points for grip angle and rotation, tool-free telescoping width adjustment, and weigh approximately 18 pounds per handle.
The 3D Handles have their own adjustable geometry — they are not the same system as the 360 Bearing Handles’ external-hook telescopic tube. Bulletproof is also actively testing a locking capability for Smith-style use (either a swappable Smith-lock handle or a hitch-pin hook-and-latch configuration), so don’t assume every future Smith-latch behavior is already released. For now, 3D Handles are documented for ISO Arms and VTS only.
See the current 3D Handles (Pair) product page.
Adjustable Handles: Dual-Small-Hex System
The Adjustable Handles use a dual small hex system, and their behavior depends on the host equipment. On ISO Arms, the hex sleeve rotates freely, giving full access to both flat-grip and neutral-grip adjustment modes. On VTS, the fixed hex orientation means the handles still work but give offset grip variations rather than true neutral-grip adjustability.
Bulletproof explicitly says these do not fit Isolator equipment, which uses a large single hex port. A “hex” connection is not automatically the same hex connection — large single hex and dual small hex are different interfaces.

See the current Adjustable Handle (Pair) product page.
Row Handles: Dual-Hex Rowing System
The Row Handle Pair is currently documented for ISO Arms and VTS, using dual hex posts plus telescoping width, spring-pin angle adjustment, and linkage-length adjustment to change resistance-curve feel and leverage. Each handle weighs approximately 15 pounds.
The reason this belongs in a compatibility guide isn’t the exercise list — it’s the interface: dual hex posts. Verify that your specific ISO Arms or VTS configuration exposes the compatible posts before ordering.

See the current Row Handle (Pair) product page.
Swivel Handles: VTS Barbell Latch
The Swivel Handle Pair is currently documented as a VTS-specific barbell-latch product that drops into the existing VTS barbell latch, with front-hole (straight) hook and hitch-pin (curved, short, or long) hook options, articulating movement, a dual bearing system, and adjustable rigidity.
Bulletproof currently positions this as VTS-only, with adapters for other Bulletproof products described as “coming soon” — so treat it as VTS-specific for now, closer to the direct-latch ISO Handles in mounting concept than to Hexport or dual-small-hex products.
See the current Swivel Handle (Pair) product page.
What About ISO Arms?
ISO Arms are important because several advanced handles are most useful there. The current pages for 3D Handles, Adjustable Handles, and Row Handles all document ISO Arms use, which makes ISO Arms a separate handle platform from the VTS barbell-latch ecosystem. This is one of the places where the Bulletproof catalog starts making more sense if you think in interfaces instead of product names.
Interface 1 — VTS Barbell Latch
Examples: ISO Handles Attachment, Swivel Handles.
Interface 2 — VTS Hexport
Example: Hexport ISO Handles.
Interface 3 — Dual Small Hex / Dual Hex
Examples: Adjustable Handles, Row Handles, selected ISO Arms/VTS configurations.
Interface 4 — VTS Telescopic System
Example: 360 Bearing Handles.
Interface 5 — Articulated Product-Specific System
Example: 3D Handles in their documented ISO Arms/VTS configurations.
Interface Checks Go Beyond Rack Fit
A good compatibility check should not stop at “does this fit a 3×3 rack?” It should also ask: full VTS or VTS Lite? Does the trolley have hexports? Does the attachment require the barbell latch? Does it require dual small hex? Does it use a telescopic tube? Does the user own ISO Arms?
Check rack fit with the Rack Compatibility Builder, then confirm the attachment interface against the matrix above.
How to Buy Handles Without Making a Mistake
Before ordering, write down: (1) host product — VTS / VTS Lite / HOME / ISO Arms / Isolator; (2) exact connection — barbell latch / Hexport / dual small hex / telescopic tube / other; (3) whether an intermediate part is required; (4) whether the manufacturer currently documents that combination; (5) whether the handle is meant for bilateral, unilateral, fixed or articulated movement.
If any of those are unclear, stop before ordering. “Same brand” is not a compatibility standard.
Safety
A handle is part of the load path. Do not improvise adapters, pins or hooks just because two parts are physically close in size. A partially engaged hex interface, loose latch or unverified adapter can fail under dynamic load. Use the manufacturer’s documented connection method.
Final Take
Bulletproof does not have one handle ecosystem — it has several overlapping handle ecosystems: full-VTS latch, VTS Hexport, dual-small-hex/dual-hex, VTS telescopic tube, and articulated product-specific systems. Once you identify the interface first, the catalog becomes much easier to understand.
