XL VIT Users

English XL Variable Incidence Tribometer

Current Users

The most advanced investigators of slip resistance phenomena in the United States use the English XL VIT. Many are in contact with us to discuss unusual circumstances or to ask advice on the management of difficult cases.  When you own an English XL VIT, you are part of the technology with the capability to take credible readings that can be used for safety engineering, safer product development, risk management, or in courts of law.

This listing of owners and operators of the English XL VIT shows what a distinguished group they really are.  Many of them have provided links to their Web sites for your convenience.  If you and your enterprise are involved with the use of the English XL VIT and are not yet listed here, call and you too can appear on this distinguished list!
