Deltana 2SBCS 2" Solid Brass Surface Bolt, Concealed Screws, HD

The Deltana 2SBCS is a 2 inch bolt, which is the short end of the surface bolt range. That size suits an inactive leaf on a French or double door, a cabinet door, a closet pair, or a screen or storm door where you just need to pin the leaf top and bottom. On a tall exterior leaf where you want reach up to a header or down into a floor strike, a longer body is the better call: the Emtek 8511 solid brass surface bolt runs 6 inches, and the Ives SB360 comes in a 12 inch length. Same job, more bar and more mounting screws holding it.

No mortising for the bolt itself. It is a surface mounted bolt, so the body screws flat onto the face of the door and the only boring you do is the strike hole in the jamb, header, or floor that the 2 inch bar drops into. That is what makes it a retrofit part: an existing door with no bolt prep takes it without routing, and if you pull it later you are patching screw holes, not a mortise pocket.

For a labeled opening, specify a bolt that carries a fire rating on its own record. The Ives SB1640 is a fire rated surface bolt in brass construction with a 1 inch throw, and the Ives SB1600 is a fire rated heavy duty steel surface bolt with a 3-1/2 inch throw. The Deltana 2SBCS is a 2 inch solid brass surface bolt with concealed screws, chosen for appearance and clean fastener concealment on non-labeled doors such as closets, French doors and inactive leaves that do not carry a label.

The Ives SB1630 is the keyed option - a heavy duty steel locking surface bolt with a 1 inch throw and keyed security, carrying a 3-hour UL listed fire rating. The Deltana 2SBCS is a hand-operated solid brass surface bolt with concealed screws and no key cylinder, so on an opening where the bolt must not be released by anyone standing at the door, the SB1630 is the one that answers that.

When the shoot needs to reach further, step to a longer body or a longer throw. The Emtek 8511 is a solid brass surface bolt in a 6 inch length, keeping the same solid brass material as the Deltana 2SBCS, which is a 2 inch solid brass bolt. If the run needs to be longer still, the Ives SB360 is a heavy-duty steel surface bolt in a 12 inch length with a 1-1/4 inch throw. Measure the distance from the bolt body to the strike point before choosing.

The mounting screws sit behind the bolt body rather than showing on the face, so once it is installed you see a clean brass plate with no fastener heads. Two things follow from that. It looks like a piece of trim rather than utility hardware, which matters on a visible interior pair. And the fasteners are not exposed to anyone standing on the wrong side of the door with a screwdriver. Deltana sells it as a contemporary alternative for exactly those reasons.

Solid brass, both the body and the substrate, not a plated pot metal casting. That is what you want on a bolt that gets thrown by hand several times a day, and it is why the finishes hold up: brass takes a plated or PVD finish and wears rather than flaking. If your opening is a service door or a back-of-house pair that takes abuse from carts, a steel bolt like the Ives SB1600 or the ABH HD1805 with its stainless steel bar is the tougher body.

Nine finishes, so you can match the rest of the openings rather than settling. Polished Brass, PVD Polished Brass, Antique Brass, Polished Chrome, Brushed Chrome, Brushed Nickel, Antique Nickel, Oil Rubbed Bronze, and Paint Black. The PVD polished brass is the one to specify if the bolt is on an exterior or high-humidity opening and you do not want the lacquer to break down; standard polished brass is the match for existing lacquered brass trim.

Two per inactive leaf on a standard pair, one at the top into the header and one at the bottom into the floor or threshold. That pins the inactive leaf so the active leaf has something to latch against. The 2SBCS is sold each, so a pair of doors is a quantity of two, and a set of French doors with two inactive leaves is four. Order the same finish across all of them.

It does not. The 2SBCS is a thumb-operated slide bolt, thrown and retracted by hand from one side only, with nothing to key. If you need the bolt secured against retraction, the Ives SB1630 is a heavy duty steel surface bolt with keyed security and a 1 inch throw, and it carries a 3-hour UL listing. That is the one to spec where the inactive leaf has to stay locked down and out of reach of whoever is in the room.

No handing. A surface bolt mounts wherever you screw it, so it works on a left or right leaf without ordering anything different. What does decide the install is which face it lands on: the bolt operates only from the side it is mounted on, so it goes on the secure side, the interior of an exterior pair or the inside of the room you want controlled. Get that backwards and anyone on the outside can throw and release it.

Delaney offers two solid brass surface bolts that sit in the same decorative territory: the Delaney Solid Brass Surface Bolt is the plain-profile version, and the Delaney Decorative Solid Brass Surface Bolt carries an ornamented plate. All three are solid brass surface bolts; the Deltana 2SBCS distinguishes itself with concealed screws, so no fastener heads read on the face of the bolt once it is installed.

The Trimco 4800 Series is the commercial-specification family to weigh against the Deltana 2SBCS, which is itself classified for commercial use. Where a facility mixes labeled and non-labeled openings, the Ives heavy duty steel bolts carry ratings on their own records - the SB1630 is 3-hour UL listed, and the SB1600 and SB360 are heavy duty. A common approach is to run the rated steel bolts on the labeled openings and the solid brass 2SBCS where the finish needs to match the rest of the decorative trim.

Deltana classes the 2SBCS as commercial, and it is the heavy duty version of their concealed screw bolt. In practice it belongs on light commercial interior work, office suites, hospitality, multi-family common doors, where appearance counts as much as function. For a maintenance shop, a stockroom, or anywhere the bolt is thrown dozens of times a day, a steel heavy duty bolt such as the Ives SB1600 or ABH HD1805 is the harder-wearing choice.

The 2SBCS is a plain contemporary bar, solid brass, with the screws hidden so nothing interrupts the face. A decorative bolt like the Delaney BV7600 puts an ornamental plate or shaped end on the same mechanism for traditional and period trim. Both do the same job of pinning a leaf; you are choosing between a clean rectangle and a decorative one. Delaney also lists a plain solid brass surface bolt, 410309, if you want the straightforward version in another brand.

The ABH HD1805 is the auto-locking one - its 3/4 inch stainless steel bar locks when thrown, so it does not rely on friction to stay put. The Ives SB1630 achieves a similar result differently, using a key to secure a 1 inch throw. The Deltana 2SBCS is a manually thrown solid brass bolt with concealed screws, which suits inactive leaves and closet doors that are set and left rather than cycled daily.
