Deltana SS55BB-SEC 5" x 5" x Square Hinge, Ball Bearing, Security, Stainless Steel (Pair)

The SS55BB-SEC handles that with a security tab, not a non-removable pin. Deltana lists the option as Sec/Loc. Tab: an interlocking tab and slot in the leaves that engages when the door is closed, so the door stays captured in the frame even if the pin comes out. The pin itself is removable, so if your spec or your insurer specifically calls for NRP set screws, this is not that hinge. For a stated NRP hinge, the Hager BB1168 is a full mortise ball bearing hinge with a non-removable pin.

Only if your existing hinges are also 5 x 5 with square corners. The SS55BB-SEC measures 5" x 5" and is square cornered, so it drops straight into a square cut mortise of that size. It will not fill a 4-1/2 x 4-1/2 or 4 x 4 pocket, and it will not sit right in a frame routed with radius corners without recutting. The 0.150 inch leaf thickness is what you're mortising for in depth. If your openings are 4-1/2 x 4-1/2 square corner, look at the Orca 3535 Series ball bearing hinge instead.

That's what stainless is for here. The hinge is stainless steel through the base material, not plated steel, so it resists salt air corrosion far better than a standard steel hinge on a waterside or exposed exterior opening. Most of the comparable hinges of this size, the Don-Jo HWBB75045 and the Hager and Ives full mortise lines, are steel base. If you're replacing hinges on an oceanfront house because the last set rusted at the knuckle, the stainless base is the reason to move to this one.

Each order is a pair, two hinges. A standard door gets three hinges, so plan on ordering two pairs per opening and you'll have a spare, or order a pair and a half per door across a run of openings. Tall or heavy doors take four. Screws come with them: #12 x 1-1/4 inch wood screws for wood jambs and #12 x 1/2 inch machine screws for a metal frame, so you don't need to source fasteners separately.

Deltana rates the SS55BB-SEC as residential. It suits heavy residential and light exterior openings, waterside homes, entry doors, and similar. For a commercial entrance, a stairwell, or anything on a labeled fire door, specify a hinge rated for that duty: the Ives 3CB1HW heavy weight concealed bearing full mortise hinge or the Don-Jo HWBB74545 heavy weight ball bearing hinge are the heavy duty full mortise options here.

Not a straight swap. A 5 x 4-1/2 hinge has a 5 inch leaf height but only 4-1/2 inches across the open pair, so the SS55BB-SEC's wider 5 x 5 leaf will overhang the existing mortise on the door and jamb faces. Same height, different width. If you want to keep the current prep, the Don-Jo HWBB75045 is a 5" x 4-1/2" heavy weight full mortise ball bearing hinge. Going to 5 x 5 means recutting both mortises deeper into the face.

No, the SS55BB-SEC is a mechanical stainless steel ball bearing hinge with no wiring provision. To carry power to the lock, use an energy transfer hinge: the Command Access ETH-BB68 is a 5 knuckle heavy duty steel base energy transfer hinge, the Command Access ETH-CB70 is a 3 knuckle standard weight steel base version at a medium duty level, and the BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect. If you also need door position monitoring, the Command Access ETM-BB68 adds an integrated door position switch.

The Deltana SS55BB-SEC is a 5 inch by 5 inch square corner ball bearing full mortise hinge in stainless steel. For a smaller opening, the Orca Hardware 3535 Series is a 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge at a medium duty level, so it keeps the square corner and the ball bearing action in a smaller leaf. The Don-Jo HWBB74545 is another 4-1/2 inch by 4-1/2 inch heavy weight full mortise ball bearing hinge, supplied in satin chrome.

The SS55BB-SEC carries a security tab option rather than a non-removable pin, so if the specification on the door calls specifically for NRP, the Hager BB1168 NRP is a non-removable pin full mortise ball bearing hinge at a heavy duty level. Both are full mortise ball bearing hinges, so the mortise prep in the frame and door is the same family of cut; the difference is how the pin is secured against removal from the hinge side.

No. The SS55BB-SEC is a stainless steel full mortise ball bearing hinge with a security tab option, rated residential. A hinge intended for detention openings is a different build: the BEST BB855 is a heavy duty steel double weight concealed ball bearing prison hinge in the Detention Hardware series, and the Hager 990 STEEL is a full surface prison hinge, 3 inch by 4 inch, with a welded tip. Note the Hager is full surface rather than full mortise, so it mounts on the face of the door and frame instead of into a mortise.

The Deltana SS55BB-SEC is a stainless steel ball bearing hinge rated residential, which is why it is positioned for waterside and outdoor use where corrosion resistance matters. For a heavy duty commercial opening, the Don-Jo HWBB85045 is a heavy weight full mortise ball bearing hinge, 5 inch by 4-1/2 inch, in brass with a satin chrome finish, and the Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge with 3 knuckles at a heavy duty level. All three are full mortise, so the frame prep concept is the same; the split is stainless corrosion resistance versus heavy duty steel and brass construction.

No. The SS55BB-SEC is a full mortise hinge, which carries the door on one swing direction. For a door that swings both ways, the BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors. A pivot mounts at the top and bottom of the door rather than in a hinge mortise along the edge, so it is a different frame and floor prep entirely.

Ball bearing is the right call on a heavy door, an exterior slab, or any door with a closer on it. The bearings carry the load between knuckles so the door doesn't sag or start squealing after a season of use. The SS55BB-SEC is ball bearing. On a light interior door that gets opened a few times a day, plain bearing is fine and cheaper to buy in quantity, and the Emtek 92013 or the Orca 4040 Series are plain bearing options. At 5 x 5 you're already in heavy door territory, which is where the bearings earn their place.

No handing to specify. It's a full mortise butt hinge with square corners and a removable pin, so the same hinge works on a left or right hand door, in-swing or out-swing. Just mount it with the barrel to the side the door swings toward. What does matter on an out-swing exterior door is the security tab, since that's where an exposed pin is a real concern.

The SS55BB-SEC is built with ball bearings and a security tab for exterior and waterside duty. On a low-traffic interior door, the Emtek 91013 is a residential duty plain bearing hinge pair in plated steel, 3-1/2 inch by 3-1/2 inch with square corners, and the Delaney 3-1/2 inch by 3-1/2 inch interior residential hinge pair uses a 5/8 inch radius corner. Plain bearing hinges have no bearing races between the knuckles, which is the main construction difference from the ball bearing Deltana.

The SS55BB-SEC is a ball bearing hinge with no closing force built in, so the door needs a separate closer. If you want the hinge itself to close the door, the Stanley Security 2060R is a full mortise spring hinge with square corners, 4.5 inch by 4.5 inch, on a ferrous steel base at a heavy duty level. It shares the full mortise mounting and square corner of the Deltana in a smaller leaf size.

They are not the same. The SS55BB-SEC uses ball bearings visible between the knuckles of the barrel. The Ives 3CB1 is a steel 3 knuckle concealed bearing full mortise hinge at a medium duty level, where the bearing is hidden inside the knuckle, and the Hager 920 is a full mortise concealed plain bearing 2 knuckle steel hinge, also medium duty. If the appearance of the barrel matters for matching other doors, the knuckle count and bearing style are what change between them.

The SS55BB-SEC is a full mortise hinge, mortised into both the door edge and the frame. For a half mortise application, the Hager 1129 is a half mortise plain bearing commercial hinge, 4-1/2 inch standard weight steel at a heavy duty level, which mortises into the door and surface mounts to the frame. The Hager 990 STEEL is a full surface prison hinge if the application calls for surface mounting on both leaves.

The SS55BB-SEC is a 5 inch by 5 inch stainless steel ball bearing full mortise hinge with square corners, sold as a pair, with a hinge thickness of 0.150 and a security tab option. Standard weight commercial 5 knuckle options include the Stanley FBB191 full mortise standard weight hinge at 4.5 inch by 4.5 inch, and the McKinney MP79 MacPro full mortise 5 knuckle standard weight hinge. The differences to check against your opening are leaf size and whether you need the stainless substrate.

Three finishes: Oil Rubbed Bronze, Brushed Nickel, and Brushed Stainless. Brushed Stainless reads closest to the raw material and is the usual pick on coastal and modern exteriors. Brushed Nickel pairs with satin nickel locksets and levers. Oil Rubbed Bronze is a living finish on most lines, so if you're matching across a building, order all the openings in one go rather than piecemeal.

The tab sits in the leaf and engages a matching slot on the opposite leaf only as the door swings shut, so it lives entirely inside the hinge gap and never touches the stop or the door edge. It does mean both leaves have to be mortised at the same depth and in line. If one jamb leaf is shimmed out and the other isn't, the tab and slot won't register cleanly. Mortise to the 0.150 inch leaf thickness on both sides and it closes normally.

The SS55BB-SEC has a plain barrel with ball bearings and square corners, sold as a pair in oil rubbed bronze, brushed nickel, or brushed stainless. For a decorative barrel, the McKinney SQ3331 is a square barrel 2 knuckle decorative hinge, 4-1/2 inch by 4-1/2 inch, at a standard duty level. The square barrel and 2 knuckle build give a different sightline at the door edge than a ball bearing barrel.
