Blue Dot Safes SG-15-4
The Blue Dot SG-4 Steel Guard Safe is a heavy-duty UL Listed TL-15 commercial safe built for businesses that need certified protection for cash, firearms, jewelry, documents, records, and high-value assets. Ideal for banks, retailers, financial offices, and secure commercial environments, it features independently tested TL-15 burglary resistance against sustained professional tool attacks. A hardened steel plate and automatic relocker help resist drilling, forced entry, and tampering. With 12.5 cubic feet of interior storage and three adjustable shelves, it provides organized secure storage for larger operations. A substantial 2,300 lb build helps deter unauthorized removal. Built in the USA, the SG-4 delivers dependable high-security protection with verified burglary resistance.
