HES 4500 Series Mortise Strike
The HES 4500 series mortise strike is an electric strike designed for installation in UL 10C fire-rated frames with half-inch drywall penetration. It suits access-control projects that require a heavy-duty cast stainless steel keeper pin locking design. The unit includes two faceplates to accommodate a variety of cylindrical and mortise locksets up to a three-quarter throw.
Low-Profile 1 3/8 Depth Installation
The strike features a low-profile depth of 1 3/8 inches for simpler mounting in compatible frames. Its unique keeper pin locking design provides strength exceeding the ratings of the frame, door and locking hardware. Installers should verify frame preparation matches the strike dimensions and ensure proper alignment of the keeper pin to avoid binding or latch interference during operation.
Verify Frame Rating and Lockset Throw
Before ordering, confirm the frame carries a UL 10C fire rating and allows half-inch drywall penetration as required by the 4500 series design. Check that the existing lockset is a cylindrical or mortise type with a maximum throw of three-quarters of an inch. Ensure the faceplate options supplied match the specific lockset profile being used.
