Deltana 12SSB 12" Heavy-Duty Security Bolt, Stainless Steel

Each 12SSB is packed with one bolt, two strikes, and stainless steel screws, and it sells by the each, so a pair of doors or a top-and-bottom install means ordering two. The two strikes cover both a locked and an unlocked (held-open) position or a second mounting point, depending how you set it up. No cylinder, no keying, no trim to specify.

A surface bolt mounts on the inside face of the door and throws into a strike in the frame, head, or sill. The 12SSB is meant to add security from the inside while the other locks on the door are not in use, so it supplements a lockset rather than replacing one. Nobody can release it from outside, which is the point on a back door or an apartment entry, and also why it can't be your only lock if the door has to be operated from the exterior.

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. The Deltana 12SSB is a hand-operated heavy-duty stainless steel security bolt with no key control, meant to be thrown from the inside of the door. On a door where a specific person must be the one to secure or release the bolt, the keyed Ives SB1630 is the correct part.

The Ives SB360 heavy-duty steel surface bolt is offered in a 12 inch length with a 1-1/4 inch throw and is fire rated, so it covers the same 12 inch bolt length as the Deltana 12SSB in a fire rated steel construction. The Deltana 12SSB is a heavy-duty stainless steel security bolt in a 12 inch size. If the opening is a rated door assembly, the Ives SB360 is the one to specify; if the requirement is stainless steel material, the Deltana 12SSB is the stainless option.

The ABH HD1805 is a heavy duty surface bolt with an auto-locking 3/4 inch stainless steel bar, so it matches the Deltana 12SSB on heavy duty rating and stainless steel bar material while adding an auto-locking action. The Deltana 12SSB is a 12 inch heavy-duty stainless steel security bolt that is thrown manually. Choose the ABH HD1805 where the bolt should latch on its own, and the Deltana 12SSB where a simple manual throw is wanted.

Both the material and the substrate are stainless steel, so it's solid stainless rather than a plated pot-metal or steel body. That matters on an exterior-facing door, a coastal property, or a laundry or pool room where a plated bolt will bloom rust at the screw heads. Finish is stainless steel, the only finish the 12SSB is built in.

Length is about reach, not strength. The 12 inch 12SSB is what you want at the top of a tall door or where the strike sits well above the operating hand, or where you want the bolt body spanning enough of the rail to resist prying. On a French door or a shorter inactive leaf where you're throwing into a header just above the bolt, a 6 inch body like the Emtek 8511 solid brass surface bolt is the easier fit.

It's a surface-mounted bolt, so it screws to the face of the door with the supplied stainless screws rather than being mortised into the edge. Prep is drilling for the strikes, one in the frame, head, or sill for the thrown position. That's what makes it the practical retrofit on a door that's already hung and already bored for a lockset, no new mortise, no reboring.

The Ives heavy duty steel bolts, including the SB1600 with a 3-1/2 inch throw and the SB1630 with keyed security and a 3-hour UL listed fire rating, and the Trimco 4800 Series surface bolts are the lines to look at for a commercial opening. The Deltana 12SSB is a residential heavy-duty stainless steel bolt and is the right call on an apartment or house door where no rated assembly is involved.

The Ives SB1640 is a surface bolt with a 1 inch throw in fire rated brass construction, which is the brass option that still carries a fire rating. The other brass surface bolts, the Delaney 410309 and the Emtek 8511, are solid brass but are not fire rated bolts. The Deltana 12SSB is stainless steel rather than brass.

The Emtek 8511 is a solid brass surface bolt in a 6 inch length, half the 12 inch length of the Deltana 12SSB, and the Delaney BV7600 is a decorative solid brass surface bolt. Both are brass rather than the stainless steel of the Deltana 12SSB, which suits an interior door where the bolt is visible and being matched to brass trim. The Deltana 12SSB remains the heavy-duty stainless choice for an exterior or service door.

The Ives SB1600 is a heavy duty steel surface bolt with a 3-1/2 inch throw and is fire rated, the longest stated throw among the heavy duty steel bolts, compared with the 1-1/4 inch throw of the Ives SB360 and the 1 inch throw of the Ives SB1640. A deeper throw suits an opening where the strike sits in a recessed header or a floor condition with a gap to cross.

Deltana model 12SSB32D. The 12SSB is the 12 inch heavy duty security bolt and the 32D suffix is the stainless steel finish, which is the only finish it's built in.
