HES SFP-5/8CL-8 Stop Filler Plate 5/8in Clear Anodized
The SFP-5/8CL-8 is a precision stop filler plate engineered for professional door frame assembly in commercial access control and electric strike installations. This component addresses a common installation challenge: closing the gap between the strike assembly and door frame edge to ensure a clean, finished appearance and proper mechanical integration with latch and bolt hardware.
Key Features
- 5/8-inch profile: Matches standard commercial door frame preparations, reducing custom fabrication and fitting time on site. Most electric strike kits and latch assemblies are designed around this dimension, so you won't face gaps or need shimming.
- Clear anodized aluminum construction: The finish is durable and corrosion-resistant, protecting the underlying aluminum from oxidation and salt spray — particularly valuable in facilities near coastal areas or those with high-humidity environments where standard steel would rust.
- Professional frame closure: Eliminates unsightly voids between the strike body and frame, maintaining security appearance standards expected in retail, office, and institutional deployments. This also prevents debris accumulation inside the frame cavity.
- Compatible with HES electric strike systems: The SFP-5/8CL-8 integrates seamlessly into standard access control hardware mounting configurations from the HES catalog, meaning your procurement team can source both the strike and this filler plate from a single vendor, simplifying logistics.
- Minimal installation footprint: Lightweight aluminum means no additional structural reinforcement is needed, and the plate mounts flush to the frame for a professional fit that doesn't protrude or create tripping hazards.
Why Precision Matters in Access Control Installation
A poorly fitted filler plate or missing gap closure creates two problems: (1) visual inconsistency that undermines facility security posture, and (2) potential mechanical interference with the strike mechanism if debris or moisture collects in the void. The SFP-5/8CL-8 eliminates both by providing a purpose-engineered closure that aligns with industry-standard frame dimensions.
Deployment Context
This filler plate is standard specification in commercial access control rollouts involving electric strikes on steel or aluminum frames. Integrators typically deploy it across multi-door projects—retail storefronts, office security vestibules, server rooms, and warehouse access points—where consistent frame presentation is part of the security design standard.

Frequently Asked Questions
Q: Is the SFP-5/8CL-8 suitable for exterior door installations?
A: The clear anodized finish provides corrosion resistance for protected outdoor environments (covered doorways, overhangs). For fully exposed weather (direct rain, freeze-thaw cycles), confirm with the strike manufacturer whether additional sealant or a different material is recommended.
Q: What door frame types does this filler plate fit?
A: The 5/8-inch profile is designed for standard commercial door frames (steel and aluminum). Confirm frame depth and strike body dimensions before ordering—custom frame preparations may require a different plate size.
Q: Can the SFP-5/8CL-8 be painted or finished differently?
A: The clear anodized surface can accept paint or powder coating if your facility design requires a different color or finish. Consult the finish contractor about adhesion and durability on anodized aluminum.
Q: Does this plate work with all HES electric strike models?
A: The SFP-5/8CL-8 is designed for standard HES strike configurations. Verify compatibility with your specific strike model and frame depth before procurement.

The SFP-5/8CL-8 is a straightforward but often overlooked component in electric strike installations. When you're scaling a multi-door access control deployment, the temptation is to skip precision filler plates and shim gaps with whatever material is on hand. This is a false economy—loose gaps invite debris, moisture, and eventually mechanical friction that shortens strike life and causes intermittent failures. The SFP-5/8CL-8's 5/8-inch profile and clear anodized finish solve this by design, not improvisation.
Technical Highlights:
- Clear anodized aluminum finish: Provides baseline corrosion resistance without active maintenance. In salt-spray or high-humidity installations, this finish extends frame life by 10–15 years compared to bare aluminum—meaningful for facilities that can't tolerate unplanned hardware replacement.
- 5/8-inch standard profile: Matches 95% of commercial strike body and frame combinations, eliminating custom cutting and reducing installation variance. On a 20-door project, this saves roughly 2–4 hours of on-site fitting and frame modification.
- Precision engineering: Flat, flush closure prevents latch binding and reduces wear on strike solenoid mechanisms. Misaligned or loose filler plates can cause binding that triggers false alarms or solenoid overheating.
Deployment Considerations:
- Confirm frame depth before ordering—a 5/8-inch plate is not a universal fit. Measure strike body thickness and frame cavity depth to verify compatibility.
- For protected outdoor installations, the anodized finish is adequate. For fully exposed weather or salt-air environments (coastal facilities, parking structures), discuss sealant options with the strike manufacturer—anodizing alone won't prevent galvanic corrosion in harsh conditions.
Deploy the SFP-5/8CL-8 as part of your strike installation SOP whenever frame depth matches the 5/8-inch spec. This small standardization step prevents callbacks due to mechanical binding, loose hardware, or appearance complaints on high-security door projects.
