Emtek CY4-PSCHCTIS5-FB Deadbolt Double Inside Cylinder

Product Description

The EMTEK CY4-PSCHCTIS5-FB is a double inside cylinder designed for use with deadbolt locksets in FB, US19, and FBS finishes. This cylinder replaces or supplements the interior thumb-turn with a keyed cylinder, allowing key operation from both sides of the door. It is a hardware component installed by locksmiths, finish carpenters, or skilled general contractors during door hardware assembly or replacement. The unit measures 4.13 inches in length, 2.25 inches in width, and 1 inch in height, and weighs 0.45 pounds, making it a compact, direct-fit component for compatible EMTEK deadbolt configurations.

This inside cylinder is suited for residential and light commercial door hardware applications where double-cylinder deadbolt function is required. Typical installations include doors where interior thumb-turn access must be restricted, such as doors with glass panels or sidelights that could otherwise allow an intruder to reach in and operate the lock. It is sold as a single unit and is intended for use exclusively with EMTEK deadbolts in FB, US19, and FBS finishes.

Installation Notes

Installation is typically performed by a licensed locksmith or experienced finish carpenter. Before servicing any door lock, ensure the door is in a secure, operable position and that existing hardware is fully removed before inserting the new cylinder. Follow local building codes regarding egress requirements, as double-cylinder deadbolts may be restricted or require specific conditions in certain occupancy types. Do not force the cylinder into the housing; verify finish and keying compatibility prior to installation.
