From John Kinnear comes this timely update:
Safety Notice relating to Race Driver Restraint Harnesses
As of April 02/18 SFI has revoked certification SFI spec. 16.1 for Tanaka harnesses due to non-compliance.
All camlock type driver restraints produced by Ruian Dragon & Ruian Dongjinling the company that produces Tanaka harnesses, are to be removed from service and returned.
Should the reader be considering the purchase of a new driver restraint harness, he/she should first consult Appendix L , section 4 of the CASC race regs and view the listing of harnesses that have had their certification revoked. There are products from six different companies listed. These companies may well have other harnesses that are still certified.
