Schlage B362V505 Double Cylinder Deadbolt

Worth it for contractors who need Grade 1 security on doors with glass. The ANSI/BHMA Grade 1 certification means this deadbolt meets the highest residential security standard — not marketing fluff, but actual third-party testing for forced entry resistance. At 4.8 stars across 214 Home Depot reviews and 4.8 stars from 1,020 Ferguson customers, it delivers what Schlage promises.

This lock shines on doors with glass inserts or side-lights where a single cylinder thumbturn could be easily accessed by breaking the glass. Montana’s remote properties with long law enforcement response times need this level of security during seasonal vacancy.

Security Specifications That Actually Matter

Grade 1 ANSI/BHMA rating isn’t just a sticker. It means this deadbolt survived 250,000 lock/unlock cycles, 10 strikes with a 75-pound weight from 48 inches, and 300 pounds of force applied to the bolt without failing. The 1-inch throw with hardened steel saw-resistant core resists the hacksaw blade that cheaper deadbolts won’t.

Bolt Throw	1-inch throw with hardened steel saw-resistant core
Cylinder	5-pin C-keyway (re-keyable to 6-pin available)

The pick-resistant and drill-resistant cylinder adds another layer. Lock pickers need specialized tools and significant skill to defeat this cylinder design — not the credit card or bump key that opens cheap locks.

Double Cylinder Reality Check

Double cylinder deadbolts require keys on both sides. Great for security. Terrible for emergency exits. Common use cases for double-cylinder deadbolts like the B362V505 involve exterior doors of residential or commercial properties where security is a priority, such as entry doors facing public areas or vulnerable points of access.

Before installing, check local fire codes. Some jurisdictions restrict or prohibit double cylinder deadbolts on primary egress doors. They are less favored for interior doors or situations where quick egress is essential, due to the need for a key to unlock from the inside. Consider keeping a key near the door (but not visible through glass) for emergency exit.

The bright polished brass finish holds up better than most finishes in Montana’s UV exposure. Limited Lifetime Finish Warranty (specific to the 505 Lifetime Bright Brass finish) backs that claim.

The Bottom Line

This deadbolt costs more than hardware store specials. The all-metal chassis and bolt construction and genuine Grade 1 certification justify the premium. For doors with glass where thumbturns create vulnerability, or remote properties where security matters more than convenience, the B362V505 delivers professional-grade protection.

Schlage B60 (Single Cylinder) - features a thumbturn on the inside for faster exit remains the better choice for solid doors without adjacent glass. But when glass proximity demands key control on both sides, this double cylinder design earns its place.

FAQ
