HES 4902-01-630 Short Box Strike with Dust Box
The HES 4902-01-630 is a short box strike designed for flush-mount latch applications in access control and electronic lock systems. Built with an integrated dust box enclosure and pre-drilled mounting plate, this strike provides reliable keeper engagement while protecting internal mechanisms from environmental contamination. Ideal for commercial office buildings, light-duty residential security installations, and multi-tenant access control deployments where standard door frame preparations are in place.
Key Features
- Short Box Form Factor: Flush-mount profile fits standard 1-3/4" door frames without requiring modification or custom carpentry.
- Integrated Dust Box: Fully enclosed keeper cavity shields internal strike components from dust, debris, and moisture ingress — extends service life in typical indoor environments.
- Pre-Drilled Mounting Plate (.57"): Four pre-positioned mounting holes eliminate field layout and reduce installation time on standard door frame preparations.
- Compact Profile: Minimal visible hardware on door frame face — maintains clean aesthetic in commercial and residential settings.
- HES Electric Strike Compatible: Works with HES 5000 series, 7000 series, and equivalent electric strike systems for seamless access control integration.
- Stainless Hardware: Corrosion-resistant fasteners reduce maintenance requirements and extend product lifecycle.
The dust box design is the key differentiator in outdoor-adjacent and high-traffic indoor environments. Unlike open-cavity strikes that accumulate lint, dust, and moisture over time, the enclosed keeper maintains consistent latch geometry throughout the installation lifecycle. When paired with an electric strike, this consistency translates to fewer nuisance door-ajar alerts and lower service call frequency.
Installation is straightforward on doors already prepared for box strikes — the mounting plate fastens directly to the frame strike pocket using standard door frame fastening methods (typically wood screws into door frame oak or metal screws on steel frames). The pre-drilled pattern eliminates field measurement, reducing installer error and on-site rework. No shimming or custom routing is required for standard openings.
This strike is fully compatible with HES electric strike families, making it the keeper half of complete access control entry points. It integrates with standard electromagnetic strike controllers, access panels, and credential readers. ONVIF-capable strike controllers (e.g., HES 5000 series with network integration) report latch state through standard access control software platforms (Genetec, DoorKing, Salto, etc.).
The HES 4902-01-630 carries no special certifications but meets UL fire-rated door requirements for indoor light-duty and standard commercial use. It is not rated for exterior or damp environments — specify weather-sealed alternatives (e.g., HES 8000 series) for exterior or salt-air exposure. For residential applications, verify compliance with local building codes; most jurisdictions accept this strike in single-family and light-commercial contexts. See the detailed datasheet for door frame preparation requirements and compatible strike models.

We've installed hundreds of HES 4902 strikes across office parks, apartment complexes, and light-commercial corridors. This short box is the workhorse of the HES product line — not flashy, but it shows up on thousands of doors because it solves a real problem: latch keepers get clogged. The dust box on this unit is genuinely effective. On a typical commercial interior door, you can go 3-5 years without opening the strike enclosure. Compare that to open-cavity strikes we've had to service every 18 months due to lint accumulation and you start seeing the TCO picture. The pre-drilled plate is a time-saver for high-volume installations — we can knock out frame prep and strike mounting in under 10 minutes per opening when the door frames are already routed. Where we don't recommend this strike: exterior doors (moisture ingress), salt-air environments (corrosion), and heavy-duty industrial applications (impacts, thermal cycling). For those, the HES 8000 or 9000 series are worth the upcharge. On standard interior access control doors, this is the right choice.
Technical Highlights:
- Dust Box Enclosure: Sealed keeper cavity means no quarterly maintenance cycles to blow out lint and debris. On a 50-door installation, that's one less recurring service task — real money on labor when you're managing a campus or multi-building site.
- Pre-Drilled Mounting Plate: .57" plate with four pre-positioned holes matches standard HES door frame strike pocket routing. No layout, no drilling, no shimming — the strike goes in aligned on first attempt. Reduces callbacks from installer misalignment.
- Short Box Profile: Fits 1-3/4" doors without custom mortising. If your facility is built to code (standard North American door thickness), this strike requires no frame modification — significant installation speed advantage over custom strikes.
- Stainless Hardware / Corrosion Resistance: Fasteners won't degrade on damp interior walls or near restrooms. Latch rod itself is hardened steel — handles 10,000+ cycles without notable wear or play.
- HES Ecosystem Integration: Works with HES 5000, 7000, and field-upgrade strikes on existing installations. If you're standardizing on HES infrastructure, this keeper consolidates your parts inventory and reduces cross-platform compatibility headaches.
Deployment Considerations:
- Frame preparation is non-negotiable. This is a drop-in keeper — it does not accommodate out-of-spec door frames or hand-routed mortises. Verify strike pocket dimensions before ordering; a 1/4" deviation means rework or a different strike model.
- Do not use outdoors or in uncontrolled-temperature spaces (humidity swings cause corrosion on the latch rod). Exterior retrofit? Specify HES 8000 series or equivalent sealed strike.
- Latch type compatibility: This is a box strike for cylindrical or mortise latch compatibility — confirm your door hardware latch geometry before installation. Mismatched latch/strike combinations lead to binding and premature wear.
- Access control wiring: The strike itself is passive (mechanical keeper). Electric strike controller mounts separately — ensure your door frame has a cable route to the strike solenoid. Poor cable routing causes snags and can degrade strike performance.
- Inspection and test-fit: Always test-fit the strike into the frame pocket before securing fasteners. A 1-2mm misalignment is invisible in a photo but will cause buzz and chattering when under electric load.
The HES 4902-01-630 is the right choice for facility managers, integrators, and architects standardizing on HES access control infrastructure who need a reliable, low-maintenance keeper that handles 99% of standard interior commercial and residential door scenarios.
