Deltana DSB4045 4" x 4-1/2" Square Hinges (Pair)

The DSB4045 is a 4 inch by 4-1/2 inch leaf size, so the mortise on the door edge has to be 4 inches tall. That is the height dimension; the 4-1/2 inches is the open width across both leaves. If your existing mortises are cut for a 4 x 4 or a 3-1/2 x 3-1/2 hinge, this one will not drop in without recutting the pocket.

No. The DSB4045 is rated residential, and it uses a plain bearing rather than a ball or concealed bearing, so it isn't built for the cycle count of an office, school or multi-family corridor door. For commercial traffic, look at a ball bearing hinge such as the Orca Hardware 3535 Series 4-1/2 x 4-1/2 square corner ball bearing commercial hinge, or a heavy duty Don-Jo HWBB84545 in 4-1/2 x 4-1/2.

The pin is removable on this one, so on an out-swinging exterior door the hinge pins are accessible from outside. For that condition you want a non-removable pin hinge, such as the Hager BB1168 NRP full mortise ball bearing hinge. On an in-swinging door the knuckles are on the protected side and the removable pin is a non-issue.

The DSB4045 has square corners, which match a mortise cut by hand with a chisel or routed with a square-corner template. If your existing pockets have rounded corners, they were cut with a hinge-butt router template and you need a radius hinge instead, like the Orca Hardware 4014 Series 4 x 4 with 1/4 inch radius corners or the Delaney RH45 exterior residential hinge with a 5/8 inch radius.

The Deltana DSB4045 is a solid brass plain bearing hinge with square corners, sized 4 inches by 4-1/2 inches, sold as a pair. The nearest plain bearing residential equivalent in plated steel is the Emtek 91013, also a square corner plain bearing pair, but in 3-1/2 inch by 3-1/2 inch. The differences are the leaf size and the base material: brass on the DSB4045, plated steel on the 91013.

The DSB4045 is a residential-duty plain bearing hinge. For commercial traffic, a ball bearing hinge is the usual move: the Don-Jo HWBB74545 is a heavy weight full mortise ball bearing hinge at 4-1/2 inches by 4-1/2 inches, and the Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge with 3 knuckles. Both are full mortise like the DSB4045, so the mortise prep concept is the same, but the leaf sizes differ and the door and frame prep must match the larger leaf.

They are close but not identical. The Orca Hardware COM4040 is a 4 inch by 4 inch square corner plain bearing commercial hinge, medium duty. The Deltana DSB4045 is also plain bearing with square corners but measures 4 inches by 4-1/2 inches and is solid brass for residential use. The extra half inch of leaf width on the DSB4045 means the frame and door mortises are not interchangeable between the two.

The DSB4045 is not supplied with a non-removable pin. If the opening is an out-swinging door where pin removal is a concern, the Hager BB1168 NRP is a non-removable pin full mortise ball bearing heavy duty hinge. It is full mortise like the DSB4045, so it seats in a mortised leaf pocket, but it is a ball bearing heavy duty hinge rather than a residential plain bearing brass unit.

Each pair ships with #12 x 1-1/4 inch wood screws for the wood jamb and door, plus #12 x 1/2 inch machine screws for a metal frame. No extra fasteners needed for a standard install. Note the unit of measure is a pair, so a typical three-hinge door takes two packs.

Solid brass, not plated steel, with a leaf thickness of 0.134 inch. That matters on an exterior or coastal opening where a plated steel hinge will eventually rust through the finish. It also means the finish is applied over brass, so wear patterns age rather than flake to bare steel.

A plain bearing hinge runs metal knuckle on metal knuckle with no bearing race between them. It is quieter and lower profile, and it's fine for residential door weights. A ball bearing hinge puts a bearing between knuckles to carry more weight and more cycles, which is what you want on a heavy solid-core or a door with a closer. Comparable ball bearing options include the Emtek 94013 heavy duty ball bearing hinge and the Ives 3CB1 concealed bearing full mortise hinge.

For 3-1/2 x 3-1/2 square corner interior openings, the Emtek 91013 residential plain bearing hinges and the Schlage Residential S3P1010 square corner plain bearing mortise hinges both cover that size. The Emtek 92013 is the heavy duty plain bearing version in the same 3-1/2 inch size if the slab is solid core.

The DSB4045 is a standard plain bearing hinge with no closing action. For a self-closing opening, the Stanley Security 2060R is a full mortise spring hinge with square corners at 4-1/2 inches by 4-1/2 inches on a ferrous steel base. It shares the full mortise mounting and square corner profile of the DSB4045, but the leaf size is larger and the base is steel rather than solid brass.

The DSB4045 is a plain bearing brass hinge with no wiring provision. For power transfer to an electrified lock, the Command Access ETH-CB70 is an energy transfer hinge with a 3 knuckle standard weight steel base, and the BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect. Both are steel electrified hinges rather than decorative brass, so the finish will not match a brass hinge on the remaining leaves.

The Deltana DSB4045 is a solid brass square corner hinge that can be fitted with decorative finials. If you want a different barrel profile, the McKinney SQ3331 is a square barrel 2-knuckle decorative hinge at 4-1/2 inches by 4-1/2 inches. The DSB4045 carries the finial option on a standard barrel; the SQ3331 uses a squared barrel and a two knuckle build, and its leaf size is larger.

Not directly. The Delaney RH40xx is a 4 inch by 4 inch residential hinge pair for Castlegate offered in 5/8 inch radius and square corner, while the Deltana DSB4045 is 4 inches by 4-1/2 inches. Both are sold by the pair, but the half inch difference in the second dimension means the door and frame mortises differ, so they will not drop into the same prep.

Oil rubbed bronze. If you're matching hinges to levers and bath hardware on a remodel, that is the finish to spec across the other openings. Deltana solid brass hinges can also take decorative finials on the pin ends if you want the barrel dressed up.
