About WindRestrictor


WINDRESTRICTOR® is owned by King Penn Industries, Inc. of Dallas Texas. The brand and products were created by Robert King Pennington in 2006 when he wanted to reduce wind turbulence inside his convertible while driving with the top down. He was not happy with the less than quality options available to him on the market at the time. 

Robert designed, developed, tested and brought to market a fascinating product that would later take the market by storm.

WINDRESTRICTOR® is a registered trademark in over 40 countries.

KPI has 6 Patents on their incredibly innovative products with more pending.

In 2007 Robert passed away at 27 years old and his loving family took on the responsibility of carrying out his dreams of being a successful business owner who valued his customers above all else.
