Deltana DSPA4040 Parliament Hinge, 4" x 4", Solid Brass (Pair)

A parliament hinge has wide, projecting leaves that throw the door clear of the opening when it swings, so the door can fold back flat against the adjacent wall or trim. That is what you use when a standard butt hinge would leave the door blocking part of the opening, typically where deep casing, a projecting architrave, or a shutter needs the door to clear it. The Deltana DSPA4040 is a 4 x 4 inch solid brass parliament hinge sold as a pair, and Deltana positions it as a decorative option. For a plain door with flat trim and no clearance problem, a standard butt hinge is the simpler and cheaper answer.

The Deltana DSPA4040 is sold by the pair, so one order gets you two hinges. A typical interior door hung on two hinges takes a single pair. If you are hanging a heavier or taller door on three hinges, you need two pairs and will have one spare. Check what you are ordering carefully, because the unit of measure here is the pair, not the each.

No. The DSPA4040 is a residential hinge with a plain bearing, not a ball bearing. Plain bearing hinges are meant for lighter doors and lower cycle counts. For a high traffic opening, an office corridor, or anywhere a door closer is pulling on the hinge all day, specify a ball bearing hinge instead. Use this one on interior residential doors, apartment unit interiors, and decorative openings where the swing clearance is the reason you are buying it.

No, the DSPA4040 does not have a non-removable pin. On a door that swings out, the hinge barrels sit on the outside, so a removable pin means someone can drive the pin out and lift the door off. For an out-swing exterior or a secured storage door, specify an NRP hinge or a hinge with a security stud. On an in-swing interior door, where the barrels are on the protected side, the removable pin is a convenience because you can pull the door without unscrewing anything.

The DSPA4040 ships with #10 x 1-1/4 inch wood screws. That length bites into the jamb itself on a normal wood frame. If you are mounting into a hollow or split jamb, or replacing a hinge whose screw holes are already stripped, plan on longer screws into the framing behind, because the supplied 1-1/4 inch screw only reaches the jamb stock. This is a wood screw hinge, not a machine screw hinge, so it is not intended for a hollow metal frame with tapped hinge prep.

The DSPA4040 measures 4 x 4 inches with a leaf thickness of .157 inch. If your door and jamb are already mortised for a standard 4 x 4 hinge, the leaf outline drops in. The depth of the mortise is what to check: cut the mortise so the leaf sits flush with the face of the jamb, and if your old hinge was thinner, the mortise needs deepening slightly or the door will bind against the stop. Note that a parliament hinge sets the door further off the jamb than the butt hinge it replaces, so the door will stand proud of where it sat before.

Eight finishes: Polished Brass, PVD Polished Brass, Antique Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome, and Brushed Chrome. Two of those are worth separating. Standard Polished Brass is a lacquered brass finish that will wear over time, while PVD Polished Brass is a physical vapor deposited coating that holds up far better to handling and cleaning. If you are matching a fleet of doors and want the hinges to still look alike in five years, take the PVD version.

That is the main reason to buy them. The projecting leaves on the DSPA4040 carry the door outboard of the jamb as it opens, so the door clears deep casing or a projecting wall return and lays back closer to flat. Where it does not help: a parliament hinge does not increase the width of the opening itself, and it does not let a door open past what the adjacent wall allows. If your problem is the door hitting a radiator or a wall directly behind it, you need a stop or a different swing, not a different hinge.

Two things settle it: the size and the finish. The Deltana DSPA4040 is fixed at 4 x 4 inches, so the only choice you make is finish, and there are eight of them. Order by model DSPA4040 plus the finish name, and remember the unit of measure is the pair, so a door hung on two hinges is one unit and a door hung on three takes two. Parliament hinges are symmetrical butt-style hinges, so you are not specifying a hand.

Solid brass, both the material and the substrate. That matters on a hinge because the knuckle and pin carry the door's weight, and it also means the finish is applied over brass rather than over steel. On a plated steel hinge, a scratch through the finish starts rusting; on this one it exposes brass. The eight available finishes are all applied over that same solid brass body.
