HES 8000 Series Grade 1 Electric Strikes - Concealed No-Cut

Introduction

The HES 8000 Series is a range of Grade 1 electric strikes, designed for easy and no-cut installation. These compact, high performance strikes offer a unique concealed design and are compatible with cylindrical and mortise locksets without the time and expense of frame alterations. The HES 8000 Series provides a clean installation where you simply take your plate out and make minor vertical adjustments and the 8000 Series strike goes right into the door jamb without modification of the door frame. The keeper pin locking mechanism is robust enough to exceed the strength of the door frame and locking hardware, allowing for a reliable holding force that meets ANSI/BHMA A156.31 Grade 1 holding force. The 8000 Series strikes are field-selectable for fail-safe and fail-secure operation, available in fire-rated models (HES 8300 for cylindrical locks, HES 8500 for mortise locks), and provide various levels of versatility without sacrificing safety, security, or integrity of operation.

Technical Specifications

Designed for durability, the HES 8000 Series features 1,500 lb static holding force and 70 ft–lb dynamic impact resistance. The strike is heavy duty, cycle-tested to more than 1,000,000 cycles for reliability even in high-trafficked doors. It accommodates dual voltage input of 12V or 24V (AC or DC) at a low current draw (240μA @12V, 120μA @24V) which makes it PoE-friendly and easy to power with individual or multi-voltage power supplies. With an internally mounted solenoid and plug-in connector, wiring is simplified while maintaining a low profile. Each unit is UL 1034 burglar resistant listed, UL 294 access control listed and RoHS compliant for safety purposes. The UL listed ratings also means that the HES 8000 series meets stringent performance security and environmental quality standards.

Applications

Designed for both new installs and retrofits, the HES 8000 Series is ideal for commercial doors equipped with cylindrical latchbolts (up to 5/8″ throw) and mortise locksets (up to 3/4″ throw on the 8500 model). Its slim, concealed form factor maintains clean aesthetics and preserves the door frame’s integrity — perfect for upscale offices, retail storefronts, and any opening where modifying the frame is undesirable. Vertical adjustability allows the strike to accommodate door sag or misalignment over time, ensuring smooth locking even in less-than-perfect installations. The 8000 Series works with common frame materials including hollow metal, wood, and aluminum jambs. For fire-rated openings, the HES 8300 (cylindrical) and 8500 (mortise) variants are tested to comply with NFPA 80 guidelines for retrofitting into fire door frames, providing a code-compliant electric locking solution without altering the frame. Whether securing an office suite entry or upgrading a controlled access system in a school, this strike family provides reliable, code-compliant security with minimal installation effort.

Comparative Advantage

Unlike conventional electric strikes that often require cutting into the frame or special filler plates, the HES 8000 Series offers a true “no-cut” solution. Installation is faster and cleaner, with the strike body fitting neatly into a standard ANSI strike prep. The concealed design and included adjustment shims mean even doors with slight alignment issues can be fitted correctly, outshining competitors in retrofit scenarios. In head-to-head comparisons, the 8000 Series stands out for its combination of high strength, broad compatibility, and ease of install. Its ability to exceed Grade 1 performance while preserving the door frame makes it a game-changer for installers seeking to save time and maintain structural integrity. Overall, the HES 8000 Series delivers premium electric locking security with less work and less worry for both installers and end-users.
