Deltana 8SSB 8" Heavy-Duty Security Bolt, Stainless Steel

That's exactly what the 8SSB heavy-duty security bolt is built for. It mounts on the inside face of the door and throws into a strike, adding a second point of security that's engaged manually while you're inside. It doesn't replace a keyed lock, since there's no way to operate it from outside, so it works as backup security on top of whatever lockset is already on the door.

Everything needed to mount it ships in the box: one bolt, two strikes, and stainless steel screws. Two strikes is the useful part, one for a jamb or header mount and a spare or second position, so a single carton finishes the opening without a separate hardware order.

A surface bolt like the 8SSB throws by hand from the inside only, so once it's engaged nobody enters from outside, including maintenance with a master key. On a multi-family unit door that's a real consideration. If you need a bolt that can be secured and released with a key, the Ives SB1630 locking surface bolt is keyed. For inside-only use, storage rooms, mechanical rooms, and the inactive leaf of a pair, the 8SSB is the straightforward choice.

For a fire rated opening, go to the Ives fire rated bolts instead. The Ives SB1630 is a heavy duty steel locking surface bolt with a 1 inch throw and keyed security carrying a 3-hour UL listing. The Ives SB1600 is a heavy duty steel surface bolt with a 3-1/2 inch throw and is fire rated, and the Ives SB360 is a heavy-duty steel bolt with a 1-1/4 inch throw in a 12 inch length, also fire rated. The Deltana 8SSB is a commercial heavy-duty stainless steel security bolt intended for added security on an opening when the primary lock is not in use; specify one of the Ives units where the door assembly's listing governs.

The ABH HD1805 is the nearest match in construction. It is a heavy duty surface bolt with an auto-locking 3/4 inch stainless steel bar, so like the 8SSB it puts stainless in the bolt itself rather than plated steel or brass. The 8SSB is stainless steel throughout with square corners and ships as 1 bolt, 2 strikes, and stainless steel screws, so a single 8SSB can be prepped for two strike positions such as a flush shot into the head and a floor strike. The HD1805 adds auto-locking action on the bar; the 8SSB is a straight manual throw bolt mounted on the inside face of the door for extra security while the primary lock is not in use.

The Ives SB1630 is the one to specify. It is a heavy duty steel locking surface bolt with a 1 inch throw and keyed security, so the bolt cannot simply be retracted by anyone standing at the door. The Deltana 8SSB is a manual heavy-duty security bolt mounted on the inside of the door, giving extra security at heavy duty grade while other locks are not in use, which suits an opening where the person inside controls the bolt.

Solid stainless, not a plated finish over another base metal. Both the material and the substrate are stainless steel, and the mounting screws in the box are stainless too. For an exterior door, a pool gate, a coastal property, or a wash-down area, that matters more than the look, since a plated brass bolt will pit where this one won't.

Material and intent. The Emtek 8511 is a 6 inch solid brass surface bolt, and the Delaney 410309 and BV7600 are solid brass as well, with the BV7600 being a decorative pattern. Those are chosen to match brass door furniture on interior and residential openings. The 8SSB is 8 inches, stainless steel through the substrate, square-cornered, and specified commercial, so it's the one to pick when corrosion resistance and duty level matter more than matching a brass suite.

Yes, that's a standard application for a heavy-duty surface bolt, and the two strikes in the box cover it. Mount the bolt on the inactive leaf and take the strike into the header or the threshold depending on whether you're throwing up or down. On a fire-rated pair, use a fire rated bolt such as the Ives SB1600 instead.

The 8SSB is an 8 inch bolt with no longer size in the model. For more reach, the Ives SB360 heavy-duty steel surface bolt comes in a 12 inch length with a 1-1/4 inch throw. Longer bolts are usually the answer on tall doors or where the bolt has to clear a wide astragal.

The Ives SB360 comes in a 12 inch length as a heavy-duty steel bolt with a 1-1/4 inch throw, four inches longer than the 8SSB's 8 inch size, which matters when the bolt has to span from a comfortable hand height up to the head strike. If the requirement is throw depth rather than plate length, the Ives SB1600 is a heavy duty steel bolt with a 3-1/2 inch throw. The Deltana 8SSB is an 8 inch stainless steel bolt with square corners.

No. The Ives SB1640 is a fire rated surface bolt with a 1 inch throw in brass construction, so it is specified where the opening's fire listing drives the selection. The Deltana 8SSB is a stainless steel heavy-duty security bolt, 8 inches, mounted on the inside face of the door to add security while other locks are not in use, and it ships with 2 strikes and stainless steel screws. Brass construction and stainless construction behave differently on an exterior or wash-down opening, so the two are not drop-in for each other.

They are not interchangeable. The Emtek 8511 is a solid brass surface bolt in a 6 inch length, two inches shorter than the 8SSB and a different material, so it will not cover the same mortise or screw pattern if you are replacing an existing 8 inch stainless bolt. The Deltana 8SSB is 8 inches, stainless steel, square cornered, and rated commercial heavy-duty. For a like-for-like replacement of an 8SSB, order the 8SSB or move to another heavy-duty stainless unit such as the ABH HD1805.

Brushed stainless is the single finish offered on the 8SSB. There is no polished, brass, or bronze option in this model, so if the rest of the door hardware is brass or oil-rubbed bronze, a brushed stainless bolt will read as a deliberate contrast rather than a match.

Square corners on the 8SSB plate. It's a small detail that decides whether the bolt looks right next to the rest of the trim, square corners line up with modern and commercial hardware, while rounded plates read more traditional. It also means the mortise or paint line you're covering has to be square-friendly.

The ABH HD1805 heavy duty surface bolt uses a 3/4 inch stainless steel bar with auto-locking, meaning it latches on its own when thrown. The Deltana 8SSB is a manually thrown heavy-duty stainless bolt. If you want the bolt to secure itself without a second motion, the auto-locking type is the one to specify. The Trimco 4800 Series is another heavy commercial surface bolt line worth pricing against it.

Price and packing are per each, one bolt per unit, with its two strikes and screws. So a building with twelve unit doors takes twelve units, not six.

Three families cover most commercial specifying. The Trimco 4800 Series is a surface bolt series, the ABH HD1805 Series is a heavy duty bolt with an auto-locking 3/4 inch stainless steel bar, and the Ives heavy duty steel line runs from the SB1600 with a 3-1/2 inch throw through the SB1630 keyed locking bolt to the SB360 in a 12 inch length. The Deltana 8SSB sits in that commercial group as an 8 inch stainless steel heavy-duty bolt with square corners, packed 1 bolt, 2 strikes, and stainless steel screws, so one part number covers both strike locations on a door.
