Deltana 6SBM 6" Modern Surface Bolt, Heavy-Duty, Solid Brass

Deltana's Modern Surface Bolts are offered with an assortment of matching strikes, so the strike is selected to suit the application (mortise into the jamb, surface on the frame, or into the floor for a bottom bolt). Decide where the bolt will throw before you order so the strike matches, and match the strike finish to the bolt finish.

A surface bolt mounts on the face of the door, on the inside, and throws into a strike to hold the inactive leaf or add a second point of security on a single door. It is the simpler, no-mortise option: no routing of the door edge, and it can be added to a door already hung. A flush bolt is mortised into the door edge and hides completely, which is what you want on a public-facing pair where a surface-mounted bar is visible and can be kicked. The 6SBM is the Modern style, solid brass, 6 inches long, and Deltana intends it for interior-side mounting only, so it will not secure a door from the outside.

For a labeled opening you need a bolt that carries a fire rating on its own listing, and the Ives steel surface bolts are the ones to look at: the SB1600 is heavy duty and fire rated, the SB1630 carries a 3-hour UL listing and adds keyed security, and the SB360 in the 12 inch length is heavy duty and fire rated. If you want brass rather than steel on a rated opening, the Ives SB1640 is fire rated brass construction with a 1 inch throw. The Deltana 6SBM is a decorative solid brass bolt for non-labeled interior use.

The Emtek 8511 is the nearest match: it is a solid brass surface bolt in a 6 inch length, the same material and length as the Deltana 6SBM, which is a 6 inch solid brass surface bolt.

Eight finishes: polished brass, unlacquered brass, antique brass, oil rubbed bronze, brushed nickel, polished chrome, brushed chrome, and paint black. Unlacquered brass is left bare and will patina over time, so it is the one to pick if you want the bolt to age into an existing set of living-finish hardware rather than stay bright. For a property manager standardizing across units, the finish list is broad enough to match most existing lever and hinge finishes.

Deltana lists the 6SBM as commercial, and it is the heavy-duty version of their Modern Surface Bolt in solid brass. That combination suits multi-family, hospitality, and office interior openings, storeroom and utility doors, and the inactive leaf of an interior pair.

The Emtek 8511 is a solid brass surface bolt in the same 6 inch length, so it is the direct like-for-like on size and material. Delaney also makes a solid brass surface bolt and a decorative solid brass version if you are matching a more traditional trim package. If the priority is durability over appearance, the ABH HD1805 is a heavy duty bolt with an auto-locking 3/4 inch stainless steel bar, and Trimco's 4800 Series is the institutional-grade option.

The Deltana 6SBM is a plain throw bolt, operated by hand from the inside face of the door. If you need the bolt itself to be locked or key controlled, the Ives SB1630 is a keyed locking surface bolt with a 1 inch throw, and the ABH HD1805 self-locks with an auto-locking stainless bar. Those are the options when the bolt has to resist being left thrown, as on a multi-family inactive leaf.

At 6 inches overall, the 6SBM is sized to throw into a strike mounted close by, typically on the jamb or frame beside the door, or at the top or bottom edge with the strike set right at the door line. It is not a long-reach bolt for spanning a gap up to a transom or down past a thick threshold. When you need that reach, step up to a longer bolt such as the Ives SB360 in a 12 inch length.

For a longer reach, the Ives SB360 is a heavy-duty steel surface bolt with a 1-1/4 inch throw offered in a 12 inch length, double the 6 inch length of the Deltana 6SBM.

The ABH HD1805 is a heavy duty surface bolt with an auto-locking 3/4 inch stainless steel bar. The Deltana 6SBM differs in both respects: it is solid brass and is a manually thrown bolt.

The Delaney BV7600 is a decorative solid brass surface bolt, and the Delaney 410309 is a plainer solid brass surface bolt. The Deltana 6SBM is a modern-styled solid brass bolt offered in eight finishes including polished brass, unlacquered brass, antique brass, oil rubbed bronze, brushed nickel, polished chrome, brushed chrome, and paint black.

Steel options include the Ives SB1600 heavy duty steel bolt with a 3-1/2 inch throw and the Ives SB360 heavy-duty steel bolt with a 1-1/4 inch throw. The Deltana 6SBM is a commercial-rated heavy-duty solid brass bolt, so it is a brass-bodied alternative where the finish match to other brass trim matters.
