Adding an electric strike to an existing commercial door can support electronic access while allowing the opening to keep its mechanical lock. Before choosing hardware, it is important to evaluate how the lock, door, frame, wiring, and access-control system will work together.
If your project also involves new or replacement frames, see our recent guide to knock-down and welded commercial door frames. Frame construction and condition can affect the preparation needed for a retrofit.
Confirm the lock and strike are compatible
An electric strike is installed at the frame and works with the door’s mechanical lock or exit hardware. When an authorized signal is received, its movable keeper releases the latch so the door can open. Allegion’s door hardware guide explains how electric strikes relate to mechanical locksets and panic hardware.
Compatibility depends on the existing hardware and opening. Before selecting a strike, identify the lock or exit device, latch type, door handing, frame material, and available space for the strike body and faceplate. An exit device may require a different strike arrangement than a standard lockset.
Share the lock or exit-device manufacturer and model when available. Photos of the door edge, frame, existing strike, and hardware can also help the project team understand the opening before recommending a retrofit.
Inspect the door and frame condition
A new electric strike will not resolve an opening that is already misaligned or unreliable. The door should close consistently, and its latch should meet the strike in the correct position. Worn hinges, a loose frame, an improperly adjusted closer, or a door that drags can interfere with dependable latching.
Frame preparation is another key consideration. The opening may need modification to fit the selected device, and the available depth and frame construction can affect which options are practical. A review of the complete opening helps identify these questions before installation begins. Seven Oaks provides commercial door and hardware retrofitting for existing facilities.
Plan wiring and access-control connections
An electric strike must be matched to the project’s electrical and access-control requirements. Confirm the strike’s voltage and power needs, the planned wire route, and how the device will connect to the access-control system. The access-control provider and door hardware team should coordinate these details so the selected components can operate together.
Consider how the opening will be used throughout the day, including how authorized users enter, how the door relatches, and how staff will respond if the system needs service. The goal is a coordinated opening where mechanical hardware, electronic control, and daily building use are all considered.
Account for egress and fire-rated openings
Security upgrades must be planned alongside safe exiting and any requirements that apply to the specific opening. Doors on exit routes and openings with fire-rated assemblies may require particular hardware and operating conditions. Review the project requirements with qualified door and access-control professionals before selecting equipment. For rated openings, consult our information about commercial fire doors and hardware.
Review the full opening before ordering
Before moving forward, gather the door and frame details, existing lock or exit-device information, access-control requirements, electrical specifications, and any project drawings. A coordinated review can help identify compatibility, frame-preparation, and installation questions early.
