Deltana ZHRBB325 Hand Rail Brackets, Zinc 3-1/4" Projection

Projection is 3-1/4 inches, measured wall face to rail. That is the number that decides whether you clear the required grip space behind the rail on a stair or deck run. The base is 1-1/4 inches, so it seats on a stud or a solid blocked wall without a large footprint. Zinc construction.

Screws are included. Each bracket is packed in an individual poly bag with matching screws, so the fasteners are finish-matched to the bracket rather than raw steel. Sold per unit, one bracket at a time, so count your runs and order accordingly. What is not supplied is any wall anchor for hollow wall, if you are not landing in a stud or in blocking you will need to add anchors rated for the load.

For more standoff, Delaney's 3-1/2 inch heavy duty handrail bracket runs a quarter inch deeper than the ZHRBB325's 3-1/4 inch projection. Going the other way, Delaney's 3 inch bracket tightens it up where the rail has to sit closer to the wall in a narrow stair. Projection is worth measuring before you commit, because it sets the knuckle clearance behind the grip and it is the one dimension you cannot adjust at install.

The Deltana ZHRBB325 is a zinc handrail bracket with a 3-1/4 inch projection and a 1-1/4 inch base, packed individually with matching screws. The nearest peer by projection is the Delaney 3-1/2 inch Heavy Duty Handrail Bracket, DLY-40615, which sits a quarter inch further off the wall, and the Delaney 3 inch Handrail Bracket, DLY-4061, which sits a quarter inch closer. If you are matching an existing run of rail where the rail centerline has to stay put, the quarter inch either way changes where the rail lands, so pick the one that matches the wall-to-rail dimension you already have rather than the one that looks closest by name.

The ZHRBB325 is a zinc bracket rated commercial with a 3-1/4 inch projection. When the rail is carrying heavier institutional traffic, the heavy duty peers are the Orca Hardware 10HD Series HD Handrail Bracket and the Orca Hardware 10XL Series HD Handrail Bracket with round base, along with the Delaney 3-1/2 inch Heavy Duty Handrail Bracket. The 10XL carries a round base, which changes the footprint on the wall and the screw pattern you drill, so confirm your blocking layout before you swap a square or oval base bracket for it.

No. The Deltana ZHRBB325 is a wall mounted handrail bracket, zinc, with a 3-1/4 inch projection that holds a handrail off a stair or deck wall. The Orca Hardware 10HD, 10ST and 10XL Series brackets each carry a door thickness range of 1-3/8 inch or 1-3/4 inch, meaning they are prepped to mount through a door leaf rather than into wall blocking. If your rail is running on a door or a glass front push-pull assembly, the Orca brackets are the ones cut for that thickness; the Deltana is for a wall or newel surface.

Seven finishes: oil rubbed bronze, brushed nickel, antique nickel, polished chrome, brushed chrome, polished brass, and antique brass. That spread is what makes it workable when you are matching existing lever and hinge finishes through a lobby or a common stair, order the bracket in the same finish family already on the doors rather than settling for a plain steel bracket.

It is a commercial-grade bracket, and it works equally well on a residential stair or a deck rail. For a multi-family or hospitality corridor stair you are typically standardizing a bracket across many runs, and this one is available in seven finishes under a single model number, which is what lets you spec one part across a building.

The ZHRBB325 is zinc through the body and substrate, and Deltana lists deck handrails as an intended application alongside interior stairs. Zinc casting with a plated decorative finish is a dry-to-sheltered material, so on a covered porch or an interior stair it is the right call, on a fully exposed coastal rail expect the plating to weather faster than the casting will.

The ZHRBB325 is the finish play, zinc with a 3-1/4 inch projection in seven decorative finishes, for stairs where the bracket is visible and needs to match the rest of the hardware. Orca Hardware's 10HD and 10XL are heavy duty series brackets, the 10XL carrying a round base rather than a shaped one. If the run is a back-of-house or service stair where nobody is matching finishes, the heavy duty Orca series is the more utilitarian pick. Delaney also lists a 3 inch bracket and a 3-1/2 inch heavy duty bracket if the ZHRBB325's 3-1/4 inch projection lands wrong for your rail.

The Orca Hardware 10ST Series is the standard duty handrail bracket and the 10HD Series is the heavy duty version of the same family; the 10XL Series is heavy duty with a round base. All three are listed with the same handrail bracket function. Against them, the Deltana ZHRBB325 is a zinc bracket with a 3-1/4 inch projection and a 1-1/4 inch base. If you are standardizing a stairwell across a property, the Orca series numbers let you run one base style at two duty levels, while the Deltana gives you a single duty level across seven finishes.

The Deltana ZHRBB325 is offered in seven finishes including polished brass, antique brass, oil rubbed bronze, polished chrome, brushed chrome, brushed nickel and antique nickel, so the finish is where it carries the decorative work on an otherwise plain 3-1/4 inch projection bracket. If you want a shaped bracket rather than a finish match, the Delaney Decorative Handrail Bracket, DLY-406111, is the decorative profile in the peer set. For a residential stair where the bracket is visible from the entry, that is the styling choice; for a back-of-house or egress stair, the finish-matched Deltana keeps the profile simple.

The Deltana ZHRBB325 uses a 1-1/4 inch base and ships in an individual poly bag with matching screws, so the replacement lands on a small footprint and you are not sourcing fasteners separately. Among the peers, the Orca Hardware 10XL Series is the one specifically described with a round base, so it will not cover a square or rectangular patch line left by an older bracket. The Delaney 3 inch and 3-1/2 inch brackets differ from the Deltana on projection rather than on being a same-footprint swap, so if the wall is already drilled, verify the hole spacing against what you are pulling off before committing.

Pricing and packaging are per bracket, each one bagged individually with its screws, so the quantity is entirely on you. Standard practice is a bracket at each end of the rail plus intermediate supports along the run, so a single continuous rail is never a single-unit order. Order the same finish across the whole run, all seven finishes share the ZHRBB325 model number.
