Deltana 6SSB 6" Heavy-Duty Security Bolt, Stainless Steel

The 6SSB ships with one bolt, two strikes, and stainless steel screws. Two strikes is the point: one gets mortised or surface-mounted into the head or jamb, the other into the threshold or floor, so a single bolt can be set up to throw either up or down depending on where you mount it on the door. Nothing else is required to hang it on a standard door beyond a drill and the prep for the strike.

For a labeled fire door opening, the Ives SB1600 is a heavy duty steel surface bolt with a 3-1/2 inch throw and a fire rating, and the Ives SB1630 is 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 6SSB is a heavy-duty stainless steel security bolt for interior door security where a fire label is not driving the hardware selection.

The 6SSB measures 6 inches. When the bolt has to reach further up a door leaf, the Ives SB360 is a heavy-duty steel surface bolt with a 1-1/4 inch throw supplied in a 12 inch length, double the plate length of the 6SSB. Note the difference in construction: the SB360 is steel where the 6SSB is stainless steel.

They are not the same device. The Deltana 6SSB is a manually thrown heavy-duty security bolt operated from the inside of the door, adding security while other locks are not in use. The Ives SB1630 is a heavy duty steel locking surface bolt with a 1 inch throw and keyed security, so it can be locked in position with a key. If the requirement is that the bolt cannot be released by anyone standing at the door, the SB1630 answers it and the 6SSB does not.

Solid stainless steel, both material and substrate, in a brushed stainless finish. That matters on exterior doors, coastal work, and wash-down areas where a plated brass or steel bolt streaks and pits. It also means the fastener screws match the bolt, so you are not putting plated screws into a stainless plate.

No. A surface bolt is a secondary, manually operated device thrown from the inside, so it only works on a door someone is standing behind, and it has to be manually released before that leaf can open. That is the right answer for the inactive leaf of a pair, a back door, a stockroom, or after-hours lockdown. It is the wrong answer for an egress door in daily traffic, where you want a lock or exit device that releases in one motion.

The Deltana 6SSB is stainless steel throughout, supplied in brushed stainless with stainless steel screws. Where the rest of the door hardware is brass, the Emtek 8511 is a solid brass surface bolt in the same 6 inch length, and the Delaney Solid Brass Surface Bolt covers the same function in brass. For a more ornamental face, the Delaney BV7600 is a decorative solid brass surface bolt.

The Ives SB1640 is a fire rated surface bolt of brass construction with a 1 inch throw. The Deltana 6SSB is a 6 inch heavy-duty security bolt of stainless steel construction with square corners, packed with 1 bolt, 2 strikes and stainless steel screws. They differ in material, in throw length, and in whether a fire rating is part of the specification.

The 6SSB is a commercial heavy-duty stainless steel surface bolt in a 6 inch length. Series-level alternatives a facility can standardize on are the ABH HD1805 Series, the Trimco 4800 Series surface bolts, and the Ives SB1600 heavy duty steel line with a 3-1/2 inch throw. Standardizing on one series keeps the strike prep and the spare parts consistent across openings.

Throw length decides how deep the bolt engages the head, sill, or adjoining leaf. Among the heavy duty steel options, the Ives SB1600 carries a 3-1/2 inch throw, the Ives SB360 a 1-1/4 inch throw, and the Ives SB1630 and SB1640 a 1 inch throw. The Deltana 6SSB is a 6 inch heavy-duty stainless steel bolt supplied with 2 strikes, so it can be set to engage at two positions on the opening.

Square corners on the plate, brushed stainless. It reads as commercial and utilitarian rather than traditional, so it lines up with square-rose and square-escutcheon trim and with other stainless door hardware. If the opening calls for a decorative solid brass bolt to match antique or period trim, the Emtek 8511 solid brass surface bolt is also a 6 inch bolt, and Delaney makes a decorative solid brass bolt in the BV7600.

They serve different jobs. The Delaney BV7600 is a decorative solid brass surface bolt, chosen where the bolt is visible and the appearance is part of the specification. The Deltana 6SSB is a commercial heavy-duty stainless steel security bolt with square corners, mounted on the inside of the door to add security while other locks are not in use. On a commercial opening carrying real traffic, the heavy-duty stainless bolt is the one specified for the duty rather than for the look.
