Orca Hardware 4" x 4" Square Corner Plain Bearing Commercial Hinge

Yes, provided the existing hinge is also 4" x 4" with square corners. The Orca 4040 Series is a full mortise hinge with square corners, so it matches a factory prep cut square rather than the 5/8" radius corners common on residential doors and frames. If the mortise in your door or frame has rounded corners, this hinge will leave a gap at each corner and you would want a radius-corner hinge instead, such as the Delaney 4" x 4" exterior residential hinge with a 5/8" radius.

The Orca 4040 Series is a plain bearing hinge, medium duty. Plain bearing means the knuckles ride metal on metal with no bearing race, which suits doors that see moderate traffic, are not especially heavy, and have no door closer pulling on them constantly. Put it on an office, storage room, or apartment interior door. On a high-traffic opening or one with a closer, go ball bearing instead: the Delaney CH401X is a 4" x 4" square corner commercial ball bearing hinge in the same size, and for heavier doors the Don-Jo HWBB74545 is a heavy weight full mortise ball bearing hinge at 4-1/2" x 4-1/2".

Not for a corridor door. Medium duty with a plain bearing is built for moderate cycle counts, and a corridor or stairwell door in a multi-family building takes heavy traffic and usually carries a closer, which is heavy duty territory. Use the Orca 4040 for unit interiors, closets, and back-of-house doors, and step up to a heavy duty ball bearing hinge like the Hager BB1168 or the Ives 3CB1HW concealed bearing hinge on the high-cycle openings.

The 4040 is a standard plain bearing butt hinge without a security pin feature. On an outswing exterior door where the barrel is on the outside, you want a non-removable pin or a security stud so the door cannot be lifted off by pulling the pin. The Deltana CSB45N is a 4-1/2" x 4-1/2" square corner hinge with a non-removable pin, the Deltana DE44R5TA is a 4" x 4" security hinge with a 5/8" radius, and the Hager BB1168 is a non-removable pin full mortise ball bearing hinge.

Not directly. Going from 3-1/2" to 4" means the mortise in both the door edge and the frame has to be cut wider and taller, and the screw holes will not line up. For a straight replacement in a 3-1/2" prep, stay in that size, for example the Emtek 91013 residential plain bearing hinge or the Emtek 92013 heavy duty plain bearing hinge, both 3-1/2" x 3-1/2" with square corners, or the Schlage Residential S3P1010 square corner plain bearing hinge.

No. The Orca COM4040 is a plain bearing full mortise hinge with no conductor path through the barrel. For a powered opening, the Command Access ETH-CB70 is an energy transfer hinge with a 3 knuckle standard weight steel base at medium duty, and the BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect. If the opening also needs door position reporting, the Command Access ETM-CB70 is an energy transfer monitor hinge with door position sensing on a 3 knuckle steel base. Order the Orca 4 x 4 for the remaining non-powered leaves in the same frame set.

The Delaney CH401X is a 4 inch by 4 inch commercial ball bearing hinge with square corners, so it matches the Orca COM4040 on size and corner style while running a ball bearing knuckle instead of the COM4040's plain bearing. Use the Delaney where the opening sees frequent cycling or carries a door heavy enough that you want bearings between the knuckles; the Orca 4 x 4 plain bearing unit covers medium duty commercial openings with square corner frame prep already cut.

The Orca COM4040 is built to a 4 inch by 4 inch leaf and will not fill a 4-1/2 inch mortise. For that prep, the Don-Jo HWBB74545 is a heavy weight full mortise ball bearing hinge at 4-1/2 inch by 4-1/2 inch in satin chrome, and the Deltana CSB45N is a 4-1/2 inch by 4-1/2 inch square hinge sold in pairs with a non-removable pin. Choose the Don-Jo where you want a full mortise ball bearing hinge for a commercial door and the Deltana CSB45N where the outswing opening calls for the NRP feature.

The Orca COM4040 carries a medium duty rating with a plain bearing knuckle. For a heavier opening, the Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge with three knuckles, and the Hager BB1168 is a full mortise ball bearing heavy duty hinge with a non-removable pin. Both put bearings in the knuckle and are rated heavy duty, which is the difference that matters on a door cycling constantly or hanging heavy. Where the door is a standard commercial leaf at medium duty, the Orca 4 x 4 plain bearing hinge is the direct fit.

Six finishes: oil-rubbed bronze, satin nickel, polished chrome, brushed chrome, polished brass, and painted black. That spread covers both the bright commercial look and the darker residential-style finishes, so a property manager matching hinges to existing levers across a building has a decent chance of a match without changing brands. Finish is the only thing you pick, the size is fixed at 4" x 4" square corner.

The Orca 4040 4" x 4" hinge is ordered by finish only, one line per finish. That is different from several hinges in this category that are packaged as sets, for example the Deltana DSB35 and the Delaney residential hinges are sold as pairs and the Schlage Residential S3P1010 comes in a pack of three. If you are hanging standard doors, count three hinges per door leaf and order the quantity you need.

No handing to call out. The 4040 is a symmetrical full mortise butt hinge, so the same part works on a left hand or right hand door. The only thing you select is finish. Handing does come into play on some hinges in this category, for instance the Stanley CECB1900R54L electrified hinge is a left-handed part, but that is a wiring-side issue that does not apply here.

Only for the doors that suit medium duty. The 4040 comes in one size, 4" x 4" square corner, in six finishes, which makes it straightforward to standardize unit doors and back-of-house openings on a single part number and one finish. Your entries, corridors, and any door with a closer should be on a heavy duty bearing hinge instead, and anything on an accessible route needs an ADA compliant product since the 4040 is not.

Full mortise, which is what the Orca 4040 is, means both leaves get recessed, one into the door edge and one into the frame rabbet. That is the standard arrangement on a wood or hollow metal door with a matching frame prep. If your door cannot be routed, for example a channel iron or clad door, you need a half mortise or full surface hinge instead, like the Hager 1129 half mortise plain bearing hinge or the Hager 990 full surface hinge.

The Orca COM4040 is classified for commercial use at medium duty, with square corners in a 4 inch by 4 inch leaf. For residential work the Delaney RH45xx is a 4 inch by 4 inch bulk exterior residential hinge with a 5/8 inch radius sold in pairs, and the Delaney RH35xx covers 3-1/2 inch by 3-1/2 inch bulk interior residential hinges at the same 5/8 inch radius. The Ives 1010RP is a steel plain bearing residential hinge with square corners in sets of three, which keeps the square corner prep if that is what the frame is cut for.

The Hager 920 is a full mortise concealed plain bearing hinge with 2 knuckle steel construction at medium duty, so it keeps the plain bearing action of the Orca COM4040 while reducing the visible knuckle count. The Ives 3CB1 is a steel 3 knuckle concealed bearing full mortise hinge, also medium duty. Both sit in the same medium duty band as the Orca 4 x 4 and hide the bearing inside the barrel.

Detention openings move to purpose built hinges. The BEST BB855 is a heavy duty steel double weight concealed ball bearing prison hinge, the Stanley BB855 is a double weight prison hinge at 5 inch by 6 inch furnished with no holes and not swaged, and the Hager 990 STEEL is a full surface prison hinge 3 inch by 4 inch with a welded tip, rated heavy duty. The Orca COM4040 is a medium duty commercial hinge and belongs on standard occupancy doors rather than secure cells.

The Deltana DE44R5TA is a 4 inch by 4 inch steel security hinge with a 5/8 inch radius corner, sold in pairs. It matches the Orca COM4040 on leaf size but uses a 5/8 inch radius corner rather than the Orca's square corner, so confirm the frame prep before ordering. The Hager BB1168 is another route, a full mortise ball bearing heavy duty hinge with a non-removable pin.

The McKinney T2314 is a non ferrous hinge, standard weight, 5 knuckle, rated medium duty - the same duty band the Orca COM4040 carries. That is the one to specify where the environment or the drawing calls for a non-ferrous base metal. The Orca 4 x 4 is zinc alloy and covers standard interior and exterior commercial openings.

Both run a plain bearing knuckle with square corners. The Emtek 92013 is a heavy duty plain bearing hinge in plated steel at 3-1/2 inch by 3-1/2 inch, sold in pairs; the Orca COM4040 is a 4 inch by 4 inch zinc alloy commercial hinge at medium duty. The decision comes down to the mortise your frame is cut for - 3-1/2 inch versus 4 inch - and the base material. Emtek also offers the 94013 in 3-1/2 inch by 3-1/2 inch square corner plated steel if you want a heavy duty ball bearing knuckle in that same smaller leaf.

Orca publishes a template for the COM40 hinge and it is linked in the downloads on the product record. Use it to lay out the mortise depth and screw pattern before you rout, especially if you are cutting fresh preps rather than replacing an existing 4" x 4" square corner hinge.

Orca Hardware COM4040, in the 4040 Series. Order it by that number plus the finish you want. It is a 4" x 4" square corner, full mortise, plain bearing, medium duty hinge.
