Fortis vault doors combine the ultimate in security with the beauty of contemporary styling. Attractive stainless exterior covers a high strength concrete and steel core panel. 

BLS sells & installs Round vault Door

VSI is re-introducing the beloved Round Vault Door, long the world symbol for security. The styling and workmanship of the early 20th Century has returned with increased security, lower overall weight and the features required today for personal safety.

 With the advancements in metallurgy and composite materials over the last century, VSI has designed the door to meet a U.L. Class III rating with the use of Hercvlite, modern day metals, a superior locking system and a flat-sill entry. In addition, an emergency inside release is offered as required in the world market.

Unlike the early 20th Century doors where a mass of ore was the deterrent for burglary protection, the VSI door relies on U.L.-tested and VSI-designed 8-inch thick Hercvlite material for the barrier. This effectively provides a barrier to meet the tools of today that are far superior to the tools of the early 20th Century. Also, Hercvlite greatly reduces the weight.
