Deltana HRB325 Hand Rail Brackets, 3-5/16" Projection

The HRB325 is a 3-5/16 inch bracket, and that figure is the projection, so the rail seat sits 3-5/16 inches out from whatever surface the base is screwed to. In practice that is the number to check against anything standing proud of your wall: on a plain drywall stair run you get a full hand wrap behind the rail, but if the bracket lands on a wainscot cap, a chair rail, or a stair skirt that already stands out from the wall face, that trim thickness comes off your knuckle room. Measure from the finished face the base will actually bear on, not from the studs.

Plan on at least 2-7/16 inches of flat, continuous surface. That is the base size of the HRB325, and the whole footprint has to bear on one plane. Mounting onto a narrow stair skirt board, a batten, or a wainscot cap narrower than 2-7/16 inches leaves part of the base hanging over an edge, which is where these pull loose. On a papered or panelled wall, check the base lands entirely on the same material rather than bridging a seam or a cap moulding.

Two Delaney brackets sit either side of the HRB325 on projection: the Delaney 3 inch Handrail Bracket pulls the rail closer to the wall, and the Delaney 3-1/2 inch Heavy Duty Handrail Bracket pushes it further out. The extra distance matters when the bracket has to clear a thick wainscot cap or a stair skirt, and the shorter one matters in a tight stair where the rail would otherwise crowd the walking line. If the standoff is not the issue and you just want the solid brass and the finish range, stay with the HRB325.

The Deltana HRB325 is built at a 3-5/16 inch size, which sets how far the rail is held off the wall. The nearest steps on either side of it are the Delaney 3 inch handrail bracket (4061) for a tighter standoff and the Delaney 3-1/2 inch heavy duty handrail bracket (40615) for a wider one. Pick by the clearance the rail needs behind the grip: a corridor where the rail has to stay close to the wall points to the 3 inch, a rail that gets a full hand wrap points to the 3-1/2 inch, and the HRB325 falls between the two.

Each HRB325 is bagged on its own with screws matched to the bracket finish, so nothing separate has to be ordered to fasten it. It is sold by the each, not in pairs or sets, so count your mounting points on the run and order one bracket per point. The handrail itself is not part of it, and neither are rail end caps or returns.

Ten finishes on the HRB325: oil rubbed bronze, brushed nickel, antique nickel, paint black, polished chrome, brushed chrome, polished brass, unlacquered brass, antique brass, and PVD polished brass. That covers the usual bronze, nickel, chrome, and brass families, so a bracket can be run to the same finish as the levers, hinges, and stops already on the floor. Because the screws ship finish matched to the bracket, the fasteners do not break the look on a run of brackets up a stair.

The HRB325 is solid brass, which is the right base metal for exterior rail work, but the finish on top of it decides how it ages. PVD polished brass is a vacuum deposited coating and is the most durable of the brass looks against weather and handling. Unlacquered brass has no coating at all, so outdoors it will darken and patina, which some jobs want and some do not. Oil rubbed bronze is a living finish too and will wear at the touch points. If you need the bracket to look the same in two years as it does on install day, go PVD.

For heavier service, look at the Delaney 3-1/2 inch Heavy Duty Handrail Bracket and the Orca Hardware 10HD Series heavy duty bracket. Orca also does the 10XL Series heavy duty bracket with a round base, which is the one to pick when the mounting surface is narrow and a round footprint sits better than a wider plate. The Deltana HRB325 is the solid brass decorative option with the deep finish range, so the trade is appearance and finish matching against the heavier bracket bodies.

The Deltana HRB325 is a solid brass bracket. Three peers are built and sold specifically as heavy duty: the Delaney 3-1/2 inch heavy duty handrail bracket (40615), the Orca Hardware 10HD Series HD handrail bracket, and the Orca Hardware 10XL Series HD handrail bracket with round base. If the specification for the building calls out a heavy duty bracket by name, those three answer it directly, and the HRB325 is the solid brass option where the finish match on the stair is driving the choice.

The Deltana HRB325 mounts on a 2-7/16 base. For a round wall base, the Orca Hardware 10XL Series is an HD handrail bracket built with a round base. Base shape matters when the bracket lands on a narrow pilaster, on tile or panel joints where a round footprint hides the layout better, or where the round profile has to match plates already on the wall. Confirm the wall blocking behind the bracket carries either footprint before you commit.

The Deltana HRB325 is solid brass and comes in finishes that suit older work, including antique brass, antique nickel, oil rubbed bronze, polished brass and unlacquered brass, which will patina on its own over time. The Delaney decorative handrail bracket (406111) is the peer built as a decorative pattern rather than a plain wall bracket. The HRB325 answers a period stair through material and finish, the Delaney through its ornamental shape, so the decision comes down to whether the rail run needs a shaped bracket or a brass one that ages into the space.

Deltana classes the HRB325 as commercial, and it is solid brass rather than a plated zinc casting, which is what you want on a rail that gets gripped every day in a lobby stair, a corridor, or a multi-family common area. It suits residential stair and deck rail work equally. Where it earns its place on a commercial job is standardizing a look across openings: ten finishes means the brackets can be run to match the door hardware already specified for the building.

All three are handrail brackets. The Orca Hardware 10ST Series is the standard bracket in that line, the 10HD Series is the HD build, and the 10XL Series is the HD build with a round base. Orca lists all three by product function as handrail brackets, so they are interchangeable in role and differ in build and base. The Deltana HRB325 is the solid brass bracket at a 3-5/16 inch projection, which is where it separates from the Orca line: choose it when the standoff dimension and a brass finish drive the job, and the Orca series when the specification names a standard or HD bracket.
