Napco Security Technologies DL1300ET/26D Narrow Stile Lock

Product Description

The NAPCO SECURITY TECHNOLOGIES DL1300ET/26D is a narrow stile lock designed for use in commercial door hardware applications. Narrow stile locks are built to fit the slim vertical rails of aluminum-framed glass doors, a common configuration in storefronts, office entryways, and light commercial facilities. This lock is sold as an individual unit and is typically installed by locksmiths, security technicians, or commercial door hardware specialists as part of an access control or physical security system.

The DL1300ET/26D is suited for narrow stile door frames where standard-width locksets will not fit. These frames are commonly found in commercial storefront doors, entrance doors with aluminum extrusions, and similar light commercial openings. The 26D designation indicates a satin chrome finish, a standard specification for commercial hardware applications requiring corrosion resistance and a professional appearance.

Key Features

• Narrow stile form factor fits slim aluminum door frames common in commercial storefronts
• Satin chrome finish (26D) provides durability and a clean, professional appearance
• Sold as a single unit for individual door installations
• Designed for integration into commercial access control and physical security systems

Compatibility

Designed as an OEM-style replacement or direct-install narrow stile lock for commercial aluminum-framed doors requiring a narrow stile lockset configuration.

Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware technician. Before installation, ensure the door frame is de-energized if the lock is part of an electrified access control system. Refer to local building codes and the door manufacturer specifications to confirm proper fitment and strike alignment before final mounting.
