Deltana 18SBM 18" Modern Surface Bolt, Heavy-Duty, Solid Brass

That's exactly what the Deltana 18SBM is built for. It's an 18 inch modern surface bolt that mounts on the face of the door, on the inside, so you throw it into a strike at the head or the sill to hold the inactive leaf fixed while the active leaf swings. Because it surface mounts, there's no mortising into the door edge, which matters on a glazed French door where the stile is too narrow to cut into. The long 18 inch body lets you reach up to a header strike from a comfortable height rather than mounting the bolt at the very top of the door.

Yes, plan on ordering the strike. Deltana builds the modern surface bolts to pair with an assortment of matching strikes, and which one you need depends on where the bolt throws: a floor or threshold strike if you're bolting down at the sill, a header or jamb strike if you're bolting up. Since the bolt comes in eight finishes, match the strike finish to the bolt when you order so the pair reads as one piece of hardware.

The Deltana 18SBM is a heavy-duty solid brass surface bolt in an 18 inch size, and the Deltana line is built around finish selection rather than fire listing. For an opening that has to carry a fire rating, the Ives SB1600 is a heavy duty steel surface bolt with a 3-1/2 inch throw that is fire rated, and the Ives SB1640 is a fire rated brass surface bolt with a 1 inch throw. The SB1600 gives the deeper throw; the SB1640 keeps the brass construction closer to the Deltana.

The Deltana 18SBM is a surface-mounted bolt operated by hand from the inside face of the door for added security, with no key. When the requirement is a bolt that cannot be released by anyone who reaches it, the Ives SB1630 is a heavy duty steel locking surface bolt with a 1 inch throw and keyed security, and it carries a 3-hour UL listed fire rating. That is the swap for a tenant-space or stockroom door where a hand-thrown bolt is not enough.

The 18SBM runs 18 inches, which needs a long clear run of stile or panel. Where that length will not fit, the Emtek 8511 is a 6 inch solid brass surface bolt, and the Ives SB360 in the US2C 12 inch length is a heavy-duty steel bolt with a 1-1/4 inch throw. The Emtek keeps the solid brass construction in a much shorter body; the Ives SB360 splits the difference on length in steel.

No. The Ives SB1640 is a fire rated brass surface bolt and the Ives SB1630 carries a 3-hour UL listing, and those listings are what the label inspection is checking. The Deltana 18SBM is a heavy-duty solid brass surface bolt for commercial doors and is specified on finish and length, not on a fire label. On a labeled opening, order the Ives; keep the 18SBM for the non-rated doors where the brass finish match is what matters.

Solid brass, both the material and the substrate are brass rather than a plated steel or zinc core. That's why it holds up in the finishes people actually specify it in, including unlacquered brass, which is meant to patina over time rather than hold a coating. For an exterior-facing door or a coastal property, solid brass is the reason to pick this over a steel bolt.

A surface bolt like the Deltana 18SBM screws onto the face of the door and is visible when the door is closed. A flush bolt is mortised into the edge or the top of the door and disappears. Surface mounting is the choice when you can't cut the door, when you're retrofitting a door that was never prepped, or when you want the hardware to show as a design element. The tradeoff is that it sits proud of the face, so check that it clears any astragal, panel molding, or applied trim where you plan to mount it.

The 18SBM is an 18 inch bolt, so on a short door, a cabinet, or a gate it's simply too long to lay out. For a compact solid brass bolt in the same decorative vein, the Emtek 8511 is a 6 inch solid brass surface bolt. If you want something in between and steel is acceptable, the Ives SB360 comes in a 12 inch length with a 1-1/4 inch throw.

No handing to specify. A surface bolt mounts to the face of the door and throws along the length of the body, so the same 18SBM works on a left hand or right hand leaf, and on an in-swing or out-swing door, as long as you mount it on the inside face. What you do have to decide is direction: whether the bolt throws up into a header strike or down into the floor, because that determines which strike you order with it.

For decorative openings, yes, and the eight finishes let one part number cover different hardware schemes in the same property. Two limits to plan around. The 18SBM is an 18 inch bolt, so every opening you put it on needs 18 inches of clear face to mount it. And it's a decorative solid brass bolt, so any fire-rated opening in the standardization needs a rated bolt instead, such as the Ives SB1600 or SB1640. A mixed spec is normal here: Deltana on the front-of-house doors, Ives on the rated ones.

The 18SBM is a solid brass surface bolt sold in eight finishes including oil rubbed bronze, polished brass, unlacquered brass and brushed nickel. On the same solid brass footing, Delaney offers a Solid Brass Surface Bolt and a Decorative Solid Brass Surface Bolt, and Emtek offers the 8511 solid brass surface bolt in a 6 inch size. The Delaney decorative model is the one to look at when the bolt is on a visible entry door and the profile matters as much as the function.

The 18SBM is a heavy-duty solid brass bolt rated for commercial use, and it is the choice when the finish has to match the rest of the door hardware. Where the door takes constant abuse and appearance is secondary, the steel bodies are the ones to look at: the Ives SB1600 is heavy duty steel with a 3-1/2 inch throw, the Ives SB360 is heavy-duty steel with a 1-1/4 inch throw in a 12 inch length, and the ABH HD1805 is a heavy duty surface bolt with an auto-locking 3/4 inch stainless steel bar. The ABH auto-locks on throw rather than relying on the user to seat it.

Throw depth decides how much engagement you get into the header or threshold. Among the comparable heavy-duty bolts, the Ives SB1600 throws 3-1/2 inches, the Ives SB360 throws 1-1/4 inches, and the Ives SB1630 and SB1640 each throw 1 inch. The Deltana 18SBM is specified by its 18 inch overall length and heavy-duty solid brass build, so where a deep header engagement is the governing requirement, the SB1600 is the one to spec.

Eight finishes: polished brass, unlacquered brass, antique brass, oil rubbed bronze, brushed nickel, polished chrome, brushed chrome, and paint black. If you're matching a building's existing hardware, the two brass options behave differently in service. Polished brass is lacquered and stays bright; unlacquered brass is bare and will darken. Paint black is the one to pair with modern black lever and hinge packages.

Deltana's modern surface bolt is a clean, squared-off profile meant to sit with contemporary hardware. If the opening calls for something more traditional, Delaney makes a decorative solid brass surface bolt in its BV7600 line, and a plainer solid brass surface bolt as well. For a commercial-spec look rather than a decorative one, the Trimco 4800 Series is the surface bolt to look at. All of those are different lengths and profiles, so confirm the length you need for the opening before you swap.

The Deltana 18SBM is a specific 18 inch heavy-duty model offered across eight finishes, so standardizing on it means standardizing on one length and picking the finish. If the facility needs a range of sizes under one part family, the Trimco 4800 Series and the ABH HD1805 Series are both catalogued as series, and Delaney groups its Solid Brass Surface Bolt and Decorative Surface Bolt as separate families. For a multi-building spec where openings vary, a series lets you hold one manufacturer across different bolt lengths.
