Schlage B600-Series Grade 1 Deadbolt with the Schlage Primus High Security Cylinder

Schlage B660 & Schlage Primus Cylinder

We combine Schlage's toughest heavy duty Grade 1 commercial deadlock with the Schlage Primus Controlled Access cylinder for the perfect high security solution. This combination is built to withstand the demands of the toughest commercial applications, but is also recommended for residential use.

The B600-Series deadlocks have solid brass or bronze cylinder collars, a security shield to prevent "ice pick attacks" and hardened steel ball bearings to protect the two heavy 1/4" mounting bolts from drilling attacks. Meets or exceeds all ANSO 156.5 Grade 1 strength and operational requirements. Door thicknesses between 1-3/4" and 2" (44mm to 51mm) with 1-1/2" or 2-1/8" (55mm) diameter holes supported.

The Primus high security cylinder adds patented key control and incorporates a patented finger pin and sidebar design providing a "dual-locking" cylinder that is bump-proof and virtually pick-proof.

  • 1" (25mm) throw high-strength steel alloy deadbolt with hardened steel roller resists cutting or sawing and kick-in attacks.
  • Precision-built solid brass 6-pin cylinders with phosphor bronze springs and nickel silver pins ensure long life and smooth operation.
  • Tough nickel silver keys for smooth, long lasting operation.
  • Exclusive wood frame reinforcer protects wood jamb against kick-in attacks. Reinforcer should be concealed under strike and anchored to jamb by two 3" (76mm) screws.
  • Free-spinning solid cylinder collar resists wrenching and prying.
  • Large inside thumbturn (if ordering single-sided version) makes it easy to throw and retract deadbolt.
  • Metal shield protects bolt from ice-pick attack through door.
  • Hardened steel balls protect mounting bolts from drill attack.
  • Bright Brass (3/605)
  • Satin Chrome (32D/626)
