Securitron -u.s. HEB-3BK-8 Header Extension Brackets

Product Description

The SECURITRON -U.S. HEB-3BK-8 is a set of header extension brackets finished in black, designed to extend the mounting header on access control door hardware installations. These brackets provide the additional offset needed to properly position electromagnetic locks or other header-mounted hardware on doors with non-standard frame profiles, oversized frames, or architectural trim that prevents flush mounting. Sold as a single unit, they are a standard component in commercial and institutional access control work performed by security hardware installers and locksmiths.

The HEB-3BK-8 is used in commercial door access control installations where the standard header mounting position does not align with the door leaf due to frame geometry or decorative trim. The 3 x 3 x 8 inch profile accommodates the offset required in these applications, and the black finish blends with dark-anodized or black-coated door hardware commonly found in commercial storefronts, office entries, and institutional facilities.

Key Features

• Black finish suits dark-anodized and black-coated door hardware installations
• 3 x 3 x 8 inch bracket profile provides consistent mounting offset for header hardware
• Sold individually, allowing single-door or paired applications as needed
• Classified under lock accessories for commercial access control systems

Compatibility

Designed as an OEM-style header extension bracket for commercial access control and electromagnetic lock installations requiring header offset mounting.

Installation Notes

Installation is typically performed by a licensed locksmith or access control technician. De-energize the door hardware and disconnect any low-voltage wiring before removing or repositioning header components. Fastener selection should suit the door frame material, and installers should follow applicable local building and fire codes governing door hardware on egress paths.
