Deltana DSB66BB 6" x 6" Square Hinges, Ball Bearing (Pair)

Deltana classes the DSB66BB as a residential hinge. It is ball bearing and solid brass, so it handles the weight and repeated swing of a heavy residential entry door better than a plain bearing hinge, but if you are specifying for a commercial opening with high daily cycles, look at a purpose-built commercial hinge instead. The Don-Jo HWBB84545 heavy weight full mortise ball bearing hinge or the Ives 3CB1HW heavy weight concealed bearing hinge are heavy duty options.

Square corners. The DSB66BB leaves are square cut, so they seat in a mortise that was routed square, typically a chiselled or template-routed pocket rather than one cut with a radius bit. If the mortises in your door and jamb have rounded corners you will need to square them out with a chisel, or choose a radius corner hinge instead. Corner style is the single most common reason a replacement hinge will not sit flush.

The DSB66BB is sold as a pair, two hinges. Most doors that call for a 6 inch hinge are heavy enough to want three or four hinges per leaf, so plan on ordering two pairs for a three-hinge hang (you will have one spare) or two pairs for a four-hinge hang. Wood screws are #14 x 1-1/2 inch; there is no machine screw pack with this hinge, so it is meant for wood jambs and wood doors, not hollow metal frames.

No. The DSB66BB ships with #14 x 1-1/2 inch wood screws and no machine screws, so it is set up for wood door and wood jamb work. A hollow metal frame needs a machine screw into a tapped hinge reinforcement. For steel frame openings, a commercial full mortise hinge such as the Don-Jo HWBB75045 or a Hager BB1168 is the right family to shop.

The DSB66BB is a solid brass, full mortise, square corner ball bearing hinge sold as a pair in a 6" x 6" size. If the opening calls for a commercial steel ball bearing hinge with the same square corner, the Orca Hardware 3535 Series is a 4-1/2" x 4-1/2" square corner ball bearing commercial hinge rated medium duty, and the Emtek 94013 is a heavy duty ball bearing hinge pair, 3-1/2" x 3-1/2" with square corners in plated steel. Both keep the ball bearing knuckle and the square corner, so the mortise pattern in the jamb stays square cornered; the leaf sizes differ from 6" x 6", so confirm the existing mortise height before ordering.

The DSB66BB is a residential-rated hinge and does not have a non-removable pin. On an outswing commercial exterior door where the barrel is accessible from outside, the Hager BB1168 is a non-removable pin full mortise ball bearing hinge rated heavy duty. If you want the bearing hidden rather than stacked in the knuckle, the Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge with 3 knuckles. Both are full mortise like the DSB66BB, so they set into the same style of jamb and door mortise.

No. The DSB66BB has square corners, and a square corner leaf will not seat in a mortise routed with a rounded corner without squaring the corners by hand. If the existing mortise is radiused, match it instead: the Orca Hardware 4014 Series is a 4" x 4" x 1/4" radius corner plain bearing commercial hinge and the 3514 Series is 3.5" x 3.5" x 1/4" radius, both medium duty; the Delaney exterior residential hinge pair is 4" x 4" with a 5/8" radius. Corner style is the first thing to confirm on a hinge swap, before size or finish.

The DSB66BB is a 6" x 6" leaf and needs a mortise cut to that height. For an opening already prepped at 4-1/2 inches, the Don-Jo HWBB74545 and HWBB84545 are heavy weight full mortise ball bearing hinges at 4-1/2" x 4-1/2" in satin chrome, and the Orca 3535 Series is a 4-1/2" x 4-1/2" square corner ball bearing commercial hinge. Where the door edge takes a wider leaf, the Don-Jo HWBB75045 is a 5" x 4-1/2" heavy weight steel ball bearing hinge and the HWBB85045 is a 5" x 4-1/2" brass version. All keep the ball bearing knuckle and the full mortise prep of the DSB66BB.

Leaf thickness is 0.205 inch. That gauge sets how much clearance you get between the door edge and the jamb when the hinge is mortised flush, so if you are replacing an existing hinge that is thinner or thicker, the door will shift in the opening and the strike may need adjusting. Cut the mortise depth to 0.205 inch so the leaf sits flush with the surface.

Ball bearings sit between the knuckles and carry the door's weight on a rolling surface instead of metal rubbing on metal. On a heavy or tall door, that is the difference between a swing that stays smooth and one that starts to bind, squeak, and sag as the knuckles wear. The DSB66BB is a 4BB hinge, four ball bearings, which is what you want under a solid door at this size. A plain bearing hinge like the Emtek 92013 is fine on a lighter interior door but is not the choice under real weight.

Ten finishes on the DSB66BB: PVD Polished Brass, Polished Brass, Unlacquered Brass, Antique Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome, and Paint Black. If you are matching hinges to existing lever sets or door pulls across a building, note the difference between PVD Polished Brass and standard Polished Brass, the PVD version is the coated one that holds its colour outdoors, and Unlacquered Brass is bare brass that will patina over time by design.

Solid brass, unlike plated steel, does not have a coating over a corroding base, so the DSB66BB stands up to exterior exposure without rusting through at the knuckles. That is the trade against a plated steel commercial hinge like the Emtek 94013 or the Orca 3535 Series, which are steel bodied and priced for volume but will show rust at the pin on a weather-exposed opening. For an exterior door where the hinge is visible, brass is the material that lasts and stays presentable.

Only if those doors are genuinely oversized. The DSB66BB is a 6 x 6 residential grade solid brass hinge, which is a specification hinge for tall or heavy wood doors, not a fleet standard for ordinary unit doors. For volume rehanging of standard openings, look at bulk residential hinges such as the Delaney RH45xx 4 x 4 exterior residential pair or the Delaney RH35xx 3-1/2 x 3-1/2 interior pair, both sold by the pair for exactly this kind of work. Keep the Deltana for the entry doors where the hinge is seen.

Several hinges in the same size class carry hardware the DSB66BB does not and require work beyond a mortise. The Command Access ETH-BB68 is an energy transfer hinge on a heavy duty steel base, and the ETM-BB68 adds an integrated door position switch, so both need wire raceways in the door and jamb. The BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect. The Stanley 2060R is a spring hinge, full mortise, square corner, 4.5" x 4.5", which closes the door on its own rather than swinging free. The BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge built for detention openings. The DSB66BB is a plain solid brass ball bearing hinge with no electrification, spring, or security feature.

The DSB66BB uses a ball bearing knuckle, which is what you want on a door carrying weight or cycling often. For a lighter interior door, a plain bearing hinge does the same job with a simpler knuckle: the Emtek 91013 is a residential plain bearing hinge pair, 3-1/2" x 3-1/2" with square corners in plated steel, and the Schlage Residential S3P1010 is a 3.5" x 3.5" square corner plain bearing mortise hinge sold in packs of three, rated medium duty. The Ives 1010RP is a steel plain bearing residential hinge with square corners in sets of three. All three keep the square corner mortise; none of them carry the solid brass leaf of the DSB66BB.

No. The DSB66BB is full mortise, meaning both leaves set into routed pockets, one in the door edge and one in the jamb. A half mortise hinge such as the Hager 1129, a half mortise plain bearing commercial hinge in 4-1/2" standard weight steel, mortises into the door but surface mounts to the frame, and a full surface hinge such as the Hager 990 STEEL prison hinge at 3" x 4" with a welded tip mounts flat to both. Those mounting methods are not interchangeable on a frame already prepped for full mortise. For a full mortise peer, the Stanley FBB191 is a 5-knuckle full mortise standard weight hinge at 4.5" x 4.5".

The DSB66BB carries a ball bearing between the knuckles, which is visible in the barrel. A concealed bearing hinge hides it: the Ives 3CB1 is a steel 3-knuckle concealed bearing full mortise hinge rated medium duty, the Hager 920 is a full mortise concealed plain bearing hinge with 2-knuckle steel construction, also medium duty, and the BEST CB1969R is a concealed bearing heavy weight pivot-reinforced hinge rated heavy duty. All are full mortise like the DSB66BB, so the prep style carries over; the barrel appearance and knuckle count do not, which matters if the openings need to look alike across a facility.

Yes, the DSB6 solid brass hinges accept decorative finials in place of the standard pin tips. That is the usual reason to spend on a solid brass hinge on a visible opening, the hinge becomes part of the trim package rather than something you hide. Finials are ordered separately from the hinge pair.

No handing. The DSB66BB is a full mortise butt hinge with a removable pin, so the same pair hangs a left or right hand door, you just orient the leaves to the swing. Handing only becomes a factor on hinges with a fixed pin or built-in electrical transfer, like the Stanley CECB1900R54L which is specified left-handed because of its wire routing.

The DSB66BB is a solid brass hinge that may be fitted with decorative finials and comes in ten finishes including PVD polished brass, oil rubbed bronze, brushed nickel, antique nickel, polished chrome, brushed chrome, polished brass, unlacquered brass, antique brass, and paint black. For a smaller decorative barrel, the McKinney SQ3331 is a square barrel 2-knuckle decorative hinge at 4-1/2" by 4-1/2", standard duty. The McKinney T2314 is a non-ferrous hinge, standard weight, 5 knuckle, which keeps a non-ferrous leaf like the brass DSB66BB.

The DSB66BB is sold by the pair, which suits ordering two or three per opening across a run of doors. Other hinges packaged the same way include the Delaney 3-1/2" x 3-1/2" bulk steel residential interior hinges with 5/8" radius sold as a pair, the Delaney 4" x 4" Castlegate hinges with 5/8" radius x square sold as a pair, the Emtek 92013 heavy duty plain bearing hinge pair in 3-1/2" x 3-1/2" square corner plated steel, and the Emtek 96213 heavy duty hinge pair in 3-1/2" x 3-1/2" square corner. Count the leaves per opening before you multiply, since sets of three cover a single door where pairs may not.
