QDB183 613 NS4 FLR LC Stanley Security Locks, Cylinders, Cores, Keyblank

Stanley's QDB100 line of Grade 1 deadbolts provides reliability, durability and strength for high security applications. The QDB100 series was designed with solid forged housing for added strength and performance life, plus anti-drill and saw-resistant features to deliver even greater security for a long-lasting deadbolt solution.

• Solid forged housing, full 1" steel throw bolt with hardened steel roller pin for saw resistance, and anti-drill design with two ball bearings for drill resistance on non-IC cylinders are just a few of the heavy-duty security features we built into our QDB100 series.
• Choose deadbolts with a SFIC option or keep your existing small format cores and use them with QDB100 series products. Standard door prep makes retrofit quick and easy
• Compartmentalized packaging makes QDB100 deadbolts easier to install.
