Don-Jo AF-260 Electric Strike Blank Filler Plate — 4-7/8" Frame Strike Prep Cover

The Don-Jo AF-260 is a commercial-grade electric strike blank filler plate designed to cover an existing 4-7/8" ANSI/ASA standard electric strike cutout or strike prep in a hollow metal door frame. When an electric strike is removed, replaced with a standard flat strike, or a frame prep is left unused, the AF-260 provides a clean, professional finish that conceals the opening and restores the frame's appearance and integrity.

This filler plate is a practical solution for renovation projects, access control upgrades, and any situation where a previously electrified opening is being converted back to mechanical operation — or where a strike prep was cut but is no longer needed.

Key Benefits

• Correct sizing for standard ANSI strike preps: The 4-7/8" length corresponds directly to the standard ANSI/ASA electric strike mortise cutout found in the majority of commercial hollow metal frames — no modification required in most applications.
• Clean finish: Covers abandoned electric strike cutouts, mislocated preps, or frame modifications during renovation and retrofit projects.
• Simple installation: Designed for straightforward frame installation, making it an efficient field solution for contractors and installers.
• Broad compatibility: Suited for hollow metal frames where the 4-7/8" ANSI strike prep is present — the most common commercial frame prep dimension for electric strikes and standard flat strikes alike.

Typical Applications

• Converting electrified openings back to standard mechanical lock hardware
• Covering unused or mislocated electric strike preps in hollow metal frames
• Renovation and remodel projects where access control is being removed or relocated
• Facility maintenance repairs to restore frame appearance after hardware changes

Who Needs This

Commercial contractors and installers performing lock hardware retrofits, facility managers upgrading or downgrading access control systems, and purchasing agents sourcing frame repair components will all find the AF-260 a straightforward, dependable solution for a very common field condition.
