WHY B.O.S. LOCK WAS BUILT

When Keith Bombaugh became an uncle, his brother made a simple request: make sure the firearms in Keith’s home were secured when his brother’s child came to visit. Keith understood the concern. He also knew that a firearm kept for protection still had to be ready when needed.

Every option he found asked him to give up one for the other. Keith didn’t believe responsible ownership should require that compromise. That is why he built B.O.S. Lock.

Fusion is the latest expression of that belief: designed to help prevent unauthorized access while staying ready for the people trusted to use it.
