HES 10790031 Hes Fp:851m-630 Electric Strike

When you need a fail-secure electric strike that integrates seamlessly with cylindrical locksets in commercial environments, the HES 10790031 delivers field-proven reliability without the complexity of specialized mounting hardware. This mortise-style strike handles the daily cycle demands of office buildings, healthcare facilities, and educational institutions where access control must work every time, without callbacks for mechanical failures or misalignment issues.

Key Features

• Fail-secure operation maintains locked state during power loss for secure perimeter control
• 630 satin stainless steel finish resists corrosion in high-traffic and coastal installations
• Mortise configuration integrates with standard door prep for faster installation
• Compatible with cylindrical locksets for straightforward retrofit projects
• Field-reversible design accommodates left-hand or right-hand door applications without ordering separate units
• Heavy-duty construction withstands continuous duty cycles in commercial traffic patterns
• Low current draw reduces power supply requirements in multi-door installations
• UL listed for code-compliant fire and life safety applications

The FP:851M series addresses a common integration challenge: replacing aging locksets with access control without complete door replacement. The mortise strike body fits standard door prep, which means you're not cutting new pockets or explaining to the GC why you need structural modifications. Field reversibility keeps your truck stock lean—one SKU handles both handing orientations, and the swap takes minutes on-site when you catch a flipped door schedule.

The fail-secure configuration makes sense for perimeter doors, IT rooms, and pharmaceutical storage where you need positive locking during power outages or system faults. Pair it with HES power supplies rated for your total door count, and verify your lockset's latchbolt projection matches the keeper depth. The 630 stainless finish maintains appearance in entryways where aesthetics matter to building management, while the UL listing keeps inspectors off your back during final walkthroughs. This is the strike you install when the project needs to pass inspection the first time and stay operational through the warranty period.
