Schroth Profi II ASM 4 Point Harness (Anti-Sub)

2028 Expiry

The Schroth Profi II ASM 4 Point Harness (Anti-Sub) integrates Schroth’s unique ASM (Anti-SubMarining) technology in a four-point system. The ideal harness for stock seats, or seats not designed for a pass-through for a sub strap, that are used in Driver Education programs.

Schroth’s ASM is an extra fold of material sewn into the inboard shoulder belt, elongating at a separate rate compared to the outboard belt. This allows two movements: the upper torso can twist slightly, and on the rebound phase, the torso is planted firmly back in the seat instead of sliding under the lap belt.

The Schroth Profi II ASM 4 Point Harness is good for use with a HANS device or other Head and Neck Restraint (HNR). The ASM shoulder strap on the ASM is 3” width, which will work with any HNR. A dual or single strap can be added to convert this belt into a 5- or 6- point system. The shoulders are ready to wrap around a roll bar, and snap-in or bolt-in attachments can be purchased.

The Schroth Profi II ASM 4 Point Harness also features a “Flex Belt.” Instead of being sewn into the harness, the cam latches and end fittings are wrapped, making configuration changes from a Pull-Up to a Pull-Down configuration quick and easy. In addition to helping you customize the use of your device for your particular situation, you can add bolt-in brackets to be wrapped in the lap belts. Snap-in brackets are standard on the lap belts.

Choose from Black, Blue, or Red! Be sure to specify Driver or Passenger side as the construction is slightly different for each.
