Specialty Frames

Frames engineered for non-standard openings — transoms, sidelites, borrowed lites, and multi-door assemblies for complex architectural designs.

When the opening requires more than a standard single or pair frame, HMF Express specialty frames are designed to match. All specialty frames use the same quality steel and manufacturing standards as our standard line.

Transom frame

Transom Frame

Fixed glazed panel above the door within the same frame assembly — available in single and pair configurations.
Sidelite frame

Sidelite Frame

One or two fixed lite panels flanking the door opening within the same assembly.
Borrowed lite frame

Borrowed Lite Frame

Glazed opening within a wall panel — no door, just a fixed vision lite in a hollow metal surround.
Multi-opening frame assembly

Multi-Opening Frame

Continuous frame system for two or more adjacent door openings sharing intermediate jambs.
Cased opening frame

Cased Opening

No rabbet — a hollow metal wrap around the opening for finish and protection without a door.
Combined transom and sidelite frame

Combined Transom + Sidelite

Full surround assembly with transom, sidelite, and door opening in a single welded frame.
Hollow metal pocket door frame

Pocket Door Frame

Frame for doors that slide into the wall — no swing clearance required, maximizes usable floor area in tight spaces.
Communicating door frame configurations

Communicating Frame

Back-to-back assembly for two independently operable doors sharing a single wall — common in hotel suites and adjoining rooms.

2-Piece Slip Frame

Split-jamb design installs from the face of a finished wall. Ideal for renovation and retrofit projects.

Bullet Resistant Frame

UL 752 ballistic-rated reinforced frames for government, courthouse, and high-security applications.

Detention Frame

Heavy-gauge reinforced frames with tamper-resistant hardware for correctional and institutional environments.

Double Egress Frame

Dutch Door Frame

Horizontally split door — top and bottom halves operate independently with rabbeted shelf at split line.

Hospital Stop Frame

Smooth, crevice-free stop profile for healthcare infection control. Eliminates gaps that harbor bacteria.

Kerfed Frame

Saw-cut kerf groove in stop accepts compression weatherstrip or smoke seal for concealed, positive sealing.

Lead Lined Frame

Lead sheet lining within frame profile for radiation shielding in medical, dental, and laboratory environments.

Radius & Angled Frame

True radius, segmented radius, elliptical, and angled head profiles for non-rectangular openings.

Stainless Steel Frame

304/316 grade stainless for healthcare, food service, and laboratory applications. 16 and 14 gauge.
