HES 7000 Series Electric Strike with Preload Release — High-Usage Cylindrical / Rim Exit

HES 7000 Series Electric Strike with Preload Release

The HES 7000 Series is the preload-release electric strike from HES — engineered to operate smoothly even when the door is under additional load that would cause a standard strike to bind or fail to release. Common Chicago examples of door preload: wind pressure on storefront doors during winter storms, HVAC stack-effect pressure differentials in high-rise office buildings, and slightly mis-aligned hinges that put lateral force on the latch. The 7000’s preload-release mechanism unlatches reliably under these conditions where the 1500 Series might bind.

What’s Confirmed by the Official HES Spec

These specifications come from HES product documentation:

• Preload-release feature: ensures smooth operation under additional door loads
• Locking cams: hardened stainless steel
• Lockset compatibility: modular design accommodates both cylindrical AND rim exit locksets
• Voltage: dual 12 / 24 VDC
• Construction: heavy-duty for high-usage applications

When the Preload-Release Feature Earns Its Keep

For most Chicago commercial doors, preload is not a problem and the 1500 or 1006 is sufficient. The 7000 becomes the right pick when:

• High-rise office buildings where HVAC stack effect creates significant pressure differentials at lobby and stairwell doors
• Storefront doors subject to Chicago winter wind pressure on the lake-facing side
• High-cycle commercial doors where over time the hinges shift slightly and the latch sees lateral force
• Doors where users have reported “the strike clicks but the door won’t open” — that’s classic preload binding, and the 7000 fixes it

Where the HES 7000 Wins in Chicago

• Commercial doors that bind under wind / pressure load
• High-rise office building entries subject to HVAC stack effect
• Multi-tenant residential lobby doors with frequent use and pressure differentials
• Healthcare facility high-traffic corridor doors
• Education facility heavily-used cylindrical openings
• Hospitality lobby and back-of-house heavy-traffic doors
• Industrial / warehouse personnel doors with door-binding conditions
• Office building elevator-lobby doors with stack-effect pressure
• Retail high-traffic back-of-house doors
• Government / municipal high-usage corridor doors
