Knob Cylinders
Medeco knob type cylinders (Key-In-Knob) are available for virtually any application. They are ideal for installations where either patented key control or UL437 protection must he retrofitted into existing hardware. Both Medeco Biaxial® and KeyMark® are available for most common hardware used. All Medeco key-in-knob cylinders are constructed of solid brass and, depending on your needs, can include drill resistant inserts. These cylinders are most commonly used in cylindrical locksets, deadbolts and padlocks from Medeco or other major manufacturers to upgrade the security level of their locks.
