Elements of a HANS(r) Device:
1. Collar pad (attached with Velcro(r))
2. Standard tether; also available in quick-disconnect (Q-D) model
3. Collar
4. Post-style helmet attachment; J-Clip style also available
5. Yoke
6. Rubber laminated to top of yoke
7. Yoke pad (attached with Velcro(r))

Tethers are used from the back of the HANS(r) collar to the helmet. These tethers are replaceable straps. They can be replaced by the end user. Simply remove the strap by taking off two Allen screws and the mounting plate. The strap is threaded through two slots on each side of the back of the device. Tethers can be adjusted for the driver. The tethers are offered in standard or quick-disconnect models.

Care of the HANS(r) With proper care, the HANS(r) can last throughout a racer's career. However, there are occasions when you should consider replacement.

If you have been involved in a hard impact, it is best to consider buying a new device (a consideration you should also give to the helmet). If it is minor, there is a good chance that the HANS(r) has withstood it well. If you are unsure, it can be tested. Do not rely on surface inspection as small cracks may not be obvious and the small cracks can compromise the integrity of the device.

Is It Worth It? The HANS(r) device is not the most inexpensive device on the market, but tests have shown it works. It will cost less than a trip to the emergency room at the hospital, so it becomes more of an investment than an expense. Countless drivers have attributed a better result to the device.

Ken Adams replaces a tether strap. Adams is using Phillips screws in the replacement. The original unit will have Allen screws. When replacing the tethers, make sure to keep the proper side up and check that the retaining clip is installed properly.
