Sdc 55-FU Electric Strike Deadbolt with Deadlatch

Product Description

The SDC Security Door Controls 55-FU is an electric strike designed to work with deadbolt and deadlatch configurations, with the deadlatch mounted above the deadbolt. Electric strikes replace a standard door frame strike plate and allow the latch or bolt to be released remotely via an electrical signal, enabling controlled access without mechanical keys. The 55-FU is built for access control applications where both a deadbolt and a deadlatch function must be supported in a single door prep. Installation and service are typically handled by licensed locksmiths, access control technicians, or security system integrators.

This electric strike is suited for commercial and institutional door openings where deadbolt security is required alongside a deadlatch for positive latching. Typical applications include office entryways, stairwell doors, and secure interior or exterior access points. The above-deadlatch configuration accommodates specific door hardware arrangements where the deadlatch sits above the deadbolt in the door frame. Consult the manufacturer data sheet to confirm door prep dimensions and strike pocket requirements before ordering.

Key Features

• Supports combined deadbolt and deadlatch operation in a single electric strike unit
• Deadlatch positioned above the deadbolt to match specific door hardware arrangements
• Designed for remote electrical release in access control systems

Compatibility

Designed as an OEM-style replacement or new-installation electric strike for commercial and institutional doors requiring a combined deadbolt and above-deadlatch configuration. Verify door prep dimensions and hardware alignment with the manufacturer data sheet before installation.

Installation Notes

Installation should be performed by a licensed locksmith or qualified access control technician familiar with electric strike wiring and door frame preparation. Disconnect and lock out all power to the access control system before working on the strike or its wiring. Confirm that the door frame mortise dimensions match the 55-FU strike body before installation. Low-voltage wiring practices and local access control codes should be followed throughout the installation.
