HES 9400 Electric Strike Slim Line Surface Mounted Solution - Satin

In this review the HES 9400 electric strike is evaluated for installers and facilities managers who need a low-profile, surface mounted solution that avoids frame cutting. The bottom line: it is a practical, heavy-duty option when a rim exit device uses a 1/2' Pullman latch and the installer wants a neat, stainless steel surface fit. The reviewer found the most compelling reason to buy is the fully encased housing that makes installation quick and preserves frame integrity while delivering Grade 1 strength and selectable voltage and fail modes.

Key Features

• Slim-line surface mount: The 9400 installs on the face of the frame without cutting, so retrofit jobs remain simple and reversible.
• Encased stainless housing: All components live inside the 5/8' thick stainless steel body, protecting internals and providing a clean finished appearance.
• Compatibility with rim devices: Designed for rim exit devices using a 1/2' Pullman latch, it removes guesswork about latch compatibility on most commercial doors.
• Field selectable operation: You can set fail secure or fail safe operation in the field and choose between 12 or 24 VDC to match existing electrics.
• Spacer plate included: The included 1/8' spacer plate accommodates variable door gaps so alignment issues are easier to correct on site.
• Long warranty: The SecuriCare five-year warranty provides extended coverage for peace of mind on commercial installs.

Who It's For

The HES 9400 is aimed at commercial locksmiths, building maintenance teams, and contractors who need a robust Grade 1 electric strike that can be surface mounted quickly to frames where cutting is undesirable or prohibited. Its slim profile and decorative cover make it suited for visible entrances where appearance matters as much as function.

It is less appropriate for installations that require a full mortise or where latch types differ from the 1/2' Pullman profile. Residential buyers with non-commercial exit hardware should consider simpler or purpose-built products instead.

Pros & Cons

Pros

• Surface mount design eliminates frame cutting and speeds up retrofit installs.
• Stainless steel, encased housing protects components and keeps a tidy finish with the decorative cover.
• Field selectable for fail safe/fail secure and 12/24 VDC for installation flexibility.
• Includes a 1/8' spacer plate and a five-year SecuriCare warranty for long-term reliability.

Cons

• Made specifically for 1/2' Pullman latch rim exit devices, so it is not universal for all latch styles.
• Surface mounted hardware may not suit projects that require a fully concealed or mortised strike for aesthetics.
