STI STI-7510E Polycarbonate Flush-Mount Lock/Strike Enclosure
Overview
The STI-7510E is a polycarbonate enclosure purpose-built for flush-mount access control and strike installations. The open-back box configuration allows the unit to recess into wall or frame openings, maintaining a clean finished appearance while housing lock and strike assemblies securely. This design is typical in commercial door access systems where you need the mechanism recessed rather than surface-mounted, particularly in environments where aesthetics and space constraints matter.
Key Features
- Polycarbonate Construction: Polycarbonate provides impact resistance and durability in high-traffic areas without the brittleness of glass or the corrosion concerns of untreated steel. This matters when the enclosure is at hand height or in locations where accidental impacts are likely.
- Open-Back Design: The open rear allows flexible integration with standard door frame and mounting bracket configurations. You mount the strike mechanism or latch assembly into the back of the enclosure, then recess the entire unit flush into the wall opening — no protruding edges to catch or break.
- Flush-Mount Profile: Recessing the STI-7510E into a prepared wall or frame opening eliminates the protrusion you'd get with a surface-mounted box. This is critical in corridors, stairwells, or any space where bump-outs create liability or obstruction.
- Door Access Integration: Compatible with standard door frame and mounting bracket systems. The enclosure accepts typical electric strike or mechanical latch assemblies without modification, keeping installation straightforward and reducing on-site customization.
- Durable Finish: Polycarbonate resists discoloration, scratches, and weathering better than many painted finishes, meaning the enclosure maintains its appearance over years of use without repainting.
- Straightforward Installation: The open-back box mounts directly into a prepared frame opening. No complex adapters or custom brackets required if you follow standard door strike mounting practices.
Integration & Compatibility
The STI-7510E is designed as a housing component for access control installations using conventional door strike and latch mechanisms. It integrates into standard door frame assemblies and works with typical electric strike, magnetic lock, or mechanical latch hardware. The polycarbonate enclosure does not contain electronics — it is a mechanical housing only. Pair it with your selected strike mechanism and security system controller to complete the access control chain.
When to Choose a Different Model
If your installation requires a surface-mounted enclosure (where a flush cutout is not feasible), consider a surface-mount box variant from the same STI family. If the environment demands steel construction for extreme durability or security hardening, look for a reinforced metal enclosure option. For outdoor or exposed locations where the polycarbonate may be subject to UV degradation or sustained weathering, a metal-housed strike assembly with protective coatings may be more appropriate.
Frequently Asked Questions
Q: What is the STI-7510E used for?
A: The STI-7510E is a polycarbonate enclosure designed to house electric strike assemblies, magnetic locks, or mechanical latches in flush-mount door access control applications. It recesses into wall or frame openings to provide a finished, protected housing for the strike mechanism.
Q: Can the STI-7510E be surface-mounted instead of recessed?
A: The STI-7510E is engineered for flush-mount (recessed) installation. Surface mounting would expose the back of the box and defeat the clean appearance and space efficiency the design provides. Contact the manufacturer or a systems integrator if a surface-mount variant is required.
Q: Is the STI-7510E weatherproof for outdoor door access?
A: The STI-7510E is a polycarbonate enclosure without explicit IP rating in available specifications. For outdoor or wet environments, verify compatibility with your strike mechanism and consult the manufacturer on moisture protection. Many outdoor door access systems use separate weatherproofing or heated/sealed housing variants.
Q: What mounting hardware and brackets are included?
A: Specific mounting hardware contents are not detailed in current documentation. Contact the manufacturer or your integrator for the exact hardware kit and any preparation requirements for your specific frame type.
Q: Can I use the STI-7510E with any electric strike?
A: The STI-7510E is designed as a general-purpose polycarbonate housing compatible with standard door frame and mounting bracket configurations. Before purchase, confirm that your chosen strike mechanism's dimensions and mounting interface align with the enclosure's open-back design. Consult the manufacturer's mounting guide if available.
Q: Is the STI-7510E (often searched as STI 7510E) suitable for high-traffic areas?
A: Yes. Polycarbonate provides good impact resistance in high-traffic corridors and stairwells. The recessed, flush-mount design also eliminates protruding edges that could be hazards. However, for extreme-security or hardened-perimeter applications, a steel enclosure may be preferable.

The STI-7510E is a straightforward mechanical housing with a specific job: get the door strike mechanism recessed and finished. The polycarbonate construction and open-back geometry are deliberate choices that reflect real-world access control constraints — you need the strike hidden from view, protected from accidental damage, and integrated seamlessly into the door frame aesthetic.
Technical Highlights:
- Polycarbonate Material: Polycarbonate resists impact and UV degradation better than acrylic, meaning the enclosure won't yellow or crack under normal use. This matters in long corridors and stairwells where the unit may see incidental contact.
- Open-Back Box Configuration: The rear is open, allowing your strike or latch assembly to mount directly into the frame without additional adapters. This reduces assembly complexity and keeps the strike aligned with the frame geometry.
- Flush-Mount Integration: Recessing the STI-7510E into a prepared wall opening eliminates the protrusion you get with surface-mounted boxes. In high-traffic areas or where code requires unobstructed passage, this design avoids both aesthetic and safety issues.
Deployment Considerations:
- The STI-7510E is a housing only — it contains no electronics, no power, and no logic. Your electric strike controller and security system manage access; the enclosure is purely mechanical protection and finishing.
- You must prepare a frame cutout before installation. Ensure the opening dimensions match the enclosure footprint and that the surrounding frame material can support the weight of the strike mechanism when mounted into the back of the box.
- Polycarbonate is not rated for submersion or continuous direct spray. If your door is exposed to weather or heavy washdown, confirm with the manufacturer that the enclosure plus your chosen strike hardware are appropriate, or specify a sealed, weatherproofed variant.
Deploy the STI-7510E when you're integrating a standard electric or mechanical strike into a commercial door where flush mounting is required for appearance, safety, and code compliance. It's a no-nonsense housing component that does one thing well — keep the strike protected and finished in a recessed opening.
