Cylinders - E Series
Best mortise and rim cylinders are machined from solid brass or bronze bar stock and available in all standard finishes. Mortise cylinders are adaptable for use with other manufacturer's locks by specifying the proper cam. (i.e. C4-standard cam, C181-Adams rite cam, etc). Mortise cylinders have the added security of an internal set screw that mounts diagonally in the cylinder wall and when tightened, holds the cylinder securely in the housing. Rim cylinders may be used with a variety of surface mounted lock hardware.
