The New Pro Ultra Lite Series HANS Device is the pinnacle of modern racing safety technology. Sharing the design of the HANS Sport II Device, the HANS Pro Ultra Lite is constructed from the lightest, highest quality carbon fiber material available. This design allows the device to have a hollow core, greatly reducing weight without sacrificing any strength or safety. The Pro Ultra Lite is available in a 20-degree medium or large, and is SFI 38.1 certified. Made In USA

NOTE: This is a high-speed video replayed in slow motion. The elapsed times on the video are marking points for the slow motion replay. Five seconds in this video equate to 100 milliseconds in real time. (An eye blink lasts 400 milliseconds.)
1-Second Mark:
The torso is held in the seat by properly tightened belts. Helmets are properly fastened.
2-Second Mark:
The torso begins to move forward due to belt elongation and compression of the dummy.
3-Second Mark:
- (Top) The unrestrained head begins to pitch forward. The elongation of the belts allows the dummy's torso to slide further forward in the seat.
- (Bottom) The friction rubber on the legs of the HANS has engaged the belts to straighten and load the tethers, enabling the helmet and head to move with the torso. The HANS keeps the head and helmet in normal relationship to the torso despite the elongation of the belts.
4-Second Mark:
- (Top) The neck loading increases as the unrestrained head reaches maximum excursion, increasing tension in the neck beyond the threshold for serious or fatal injury.
- (Bottom) The HANS continues to be held in place by the friction rubber on the legs during the forward movement of the torso. The tethers straighten fully and remain substantially horizontal, keeping the head in normal relationship to the torso.
5-Second Mark:
- (Top) Instrumentation in dummy confirms the neck tension threshold for a serious or fatal injury - 4,000 Newtons - has been crossed.
- (Bottom) The HANS restrains the head and instrumentation in dummy confirms neck tension is kept far below the threshold for serious or fatal injury.
