Valterra LLC

      In 1971 Bert Grengs started Grentec Inc., a plastic injection molding company in Burbank, CA. They began manufacturing RVgate valves, RV toilets, plumbing fittings and later some of Southern California’s iconic plastic skateboards like the “banana board”.

     In 1981 Bert retired and Valterra Products, Inc. began with his son, George Grengs, daughter-in-law, Patricia Grengs, daughter, Barbara Glennon, and son-in-law, Dennis Lunder owning the new company.

     Although the RV products were the primary business they reintroduced a skateboard line in 1984 that focused on wood decks, exciting graphics and precision bearings.

In 1985 Michael J. Fox rode a Valterra skateboard in the movie “Back to the Future” which introduced Valterra skateboards to the whole nation.

     Eventually Valterra moved away from the skateboard business and focused on the expansion of their RV business with the acquisition of many important product lines including sewer hoses, RV locks, Fridgemate Fans, and ABS tanks.
