Deltana DSB45RM Royal Hinge, 4-1/2" x 4-1/2" 5.1MM, Solid Brass (Pair)

Yes, if the existing cutout is 4-1/2 by 4-1/2 inches with square corners. The DSB45RM is a full mortise hinge sized 4-1/2" x 4-1/2" with square corners, so it matches the standard commercial-style square prep with no radius. If your door and frame are routed with rounded corners (typically 1/4 or 5/8 inch radius), this one will not sit in that pocket without rework.

Deltana lists the Royal DSB45RM as residential. It is a plain bearing hinge, which suits entry and interior doors in homes rather than high-cycle commercial openings. For a commercial door, look at a ball or concealed bearing hinge instead, such as the Orca Hardware 3535 Series 4-1/2" x 4-1/2" square corner ball bearing commercial hinge or the Ives 3CB1HW heavy weight concealed bearing full mortise hinge.

Not as a security solution on its own. The DSB45RM does not have a non-removable pin, so on an outswing door the pin sits on the exterior side and can be driven out. For an outswing opening where that matters, use a non-removable pin hinge such as the Hager BB1168 NRP full mortise ball bearing hinge.

The Royal is built at 0.2 inch leaf thickness (5.1mm), heavier than a typical residential hinge leaf, which is where the bulkier decorative look comes from. Because of that, the mortise has to be routed deeper than for a thin builder hinge or the door will bind against the stop. Check your existing pocket depth before swapping it in.

The Deltana DSB45RM Royal Hinge is a 4-1/2 inch by 4-1/2 inch solid brass full mortise hinge with square corners and a plain bearing, catalogued for residential use. For a commercial opening at the same size and corner style, the Orca Hardware 3535 Series is a 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge rated medium duty. The Stanley Security FBB191 is also a 4-1/2 inch by 4-1/2 inch full mortise standard weight 5-knuckle hinge, listed heavy duty. Both are steel-based rather than solid brass, so the decorative look of the Royal hinge does not carry over.

The Deltana DSB45RM uses a plain bearing. Where traffic calls for a bearing hinge, the Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge with 3 knuckles rated heavy duty, and the Emtek 94013 is a heavy duty ball bearing hinge pair with square corners in plated steel. The Hager BB1168 is a full mortise ball bearing heavy duty hinge furnished with a non-removable pin, which the Deltana DSB45RM does not carry.

No. The Deltana DSB45RM Royal Hinge is a plain bearing full mortise hinge with no spring and no electrical provision. For a self-closing leaf, the Stanley Security 2060R is a full mortise spring hinge with square corners at 4.5 inch by 4.5 inch, rated heavy duty. To run power through the hinge, the Stanley Security CECB1900R54L is a 4-1/2 inch by 4-1/2 inch square corner steel full mortise concealed conductor hinge in a 4-wire left-handed configuration, and the Command Access ETH-BB68 is a 5-knuckle heavy duty energy transfer hinge on a steel base. Those are different hinge types, not finishes of the same part.

No. The Deltana DSB45RM is a full mortise hinge, mortised into both the door and the jamb. For a frame that takes a half mortise hinge, the Hager 1129 is a half mortise plain bearing commercial hinge at 4-1/2 inch standard weight steel, rated heavy duty. For a surface-applied condition, the Hager 990 STEEL is a full surface hinge at 3 inch by 4 inch with a welded tip, also heavy duty. Mounting method has to match the prep before size or finish matters.

The DSB45RM is sold as a pair, two hinges. Most 4-1/2 inch doors in a residential opening hang on three hinges, so plan on ordering enough pairs to cover that. Mounting screws are #12 x 1-1/4 inch wood screws.

Seven finishes: Oil Rubbed Bronze, Bronze Medium, Bronze Rust, White Dark, White Light, White Medium, and Antique Brass. These are living and antiqued finishes over a solid brass body, so the Bronze and White variants will vary slightly piece to piece by design. If you are matching hinges already hung in a building, order all openings in the same finish at once.

No. The DSB45RM is a full mortise butt hinge sold in pairs and works on either a left or right hand door. Handing only becomes a factor with hinges that carry electrified or monitoring hardware, like the Stanley CECB1900R54L, which is ordered left-handed with a 4-wire harness.

Yes. The Deltana DSB45RM Royal Hinge is a solid brass 4-1/2 inch by 4-1/2 inch hinge sold in pairs and described as a heavy duty alternative with a bulkier decorative look. The McKinney SQ3331 is a square barrel 2-knuckle decorative hinge at the same 4-1/2 inch by 4-1/2 inch size, rated standard duty. The SQ3331 gives a square barrel two-knuckle profile rather than the Royal's brass barrel styling, so the choice is driven by the look you want at the jamb.
