Orca Hardware 3.5" x 3.5" x 1/4" Radius Corner Plain Bearing Residential Hinge

The Orca 3514 hinge is a 3-1/2 by 3-1/2 inch full mortise hinge with 1/4 inch radius corners. That matters more than the size: most residential doors routed by machine use a 5/8 inch radius pocket, and a 1/4 inch radius leaf sitting in a 5/8 inch radius mortise leaves a visible gap at each corner. Match the radius of what you pull off the door. If your existing pocket is 5/8 inch radius, Orca makes the same 3.5 x 3.5 hinge in a 5/8 inch radius corner instead. Square corner pockets (hand chiseled, common on older work) need a square corner hinge such as the Emtek 91013 residential plain bearing hinge, also 3-1/2 by 3-1/2.

Plain bearing is what the Orca 3514 uses, and it is a residential-duty hinge. Plain bearing means the knuckles ride metal on metal with no bearing race, which is fine for interior passage and bedroom doors on typical household traffic. For a heavier door, an exterior door with a closer on it, or any opening that sees constant use, step up to a bearing hinge: the Emtek 94013 is a heavy duty ball bearing hinge in the same 3-1/2 by 3-1/2 size with square corners, and the Ives 3CB1 is a medium duty three knuckle concealed bearing full mortise hinge for commercial openings.

No. The 3514 is built as a residential hinge and it is not ADA compliant, so keep it off barrier-free openings and out of commercial specs. For commercial work, look at a medium or heavy duty bearing hinge instead, such as the Ives 3CB1HW steel heavy weight concealed bearing full mortise hinge or the Hager BB1168 non-removable pin full mortise ball bearing heavy duty hinge.

Not without patching. The 3514 measures 3-1/2 by 3-1/2 inches, so it will sit short in a 4 inch mortise and leave exposed pocket at top and bottom, and the screw holes will not line up with the existing frame holes. Replace like for like on size. In 4 by 4, the Delaney RH40xx and RH45xx residential hinges and the Delaney CH401X commercial ball bearing hinge are the sizes to look at.

The Orca 3514 is a plain bearing residential hinge and is not the NRP option. For a pin that cannot be pulled from the hinge side, the Deltana CSB45N is a 4-1/2 inch by 4-1/2 inch square hinge pair with a non-removable pin, and the Hager BB1168 NRP is a full mortise ball bearing heavy duty hinge with a non-removable pin. Deltana also lists the DE44R5TA at 4 inch by 4 inch with 5/8 inch radius corners as a steel security hinge pair.

The Schlage Residential S3P1010 matches it most directly: 3.5 inch by 3.5 inch, plain bearing, full mortise, sold in packs of three. The difference is the corner. The Orca 3514 has 1/4 inch radius corners, while the S3P1010 has square corners, so the two are only interchangeable if the door and jamb mortises match the corner shape already cut. Emtek 91013 is the other near match at 3-1/2 inch by 3-1/2 inch plain bearing residential, also square corner, in plated steel and sold as a pair.

The Delaney RH35xx is the match for that mortise: 3-1/2 inch by 3-1/2 inch steel residential interior hinge with 5/8 inch radius corners, sold in pairs. Radius corners are not interchangeable between 1/4 inch and 5/8 inch without recutting the mortise, so measure the corner arc on the hinge coming out of the door before ordering. The Orca 3514 is the 1/4 inch radius version of the same 3.5 inch by 3.5 inch size.

The Orca 3514 is built for residential applications with a plain bearing, which suits interior doors on normal household traffic cycles. For a commercial opening, the Ives 3CB1 is a medium duty concealed bearing full mortise hinge for commercial-grade use, and the Ives 3CB1HW is the heavy weight concealed bearing version of the same 3-knuckle full mortise design. Concealed bearing carries the load on a bearing race rather than knuckle-on-knuckle contact, which is what changes with door weight and cycle count.

No. The Orca 3514 is a plain bearing hinge with no wire path through the leaf. Power transfer needs a purpose-built hinge: the Command Access ETH-CB70 is a 3-knuckle standard weight energy transfer hinge on a steel base, the ETH-BB68 is the 5-knuckle heavy duty version, 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 monitoring, the Command Access ETM-CB70 adds door position sensing on the 3-knuckle steel base.

Nine finishes across the 3514 hinge: Oil-Rubbed Bronze, Electroplated Dark Bronze, Satin Nickel, Painted Black, Satin Chrome, Brushed Chrome, Brushed Zinc, Bright Brass, and Satin Brass. That covers the usual residential lockset finishes, so a property manager standardizing a building can pull one hinge across dark bronze, black, nickel, and brass doors without changing hinge size or corner style.

Zinc alloy is the material on the 3514, and it is specified for residential use with a plain bearing. Zinc alloy holds a decorative finish well on interior passage and closet doors. For an exterior door, which carries more weight and weather, a steel base hinge is the better call: the Delaney RH45xx is a 4 by 4 bulk residential exterior hinge with a 5/8 inch radius, and the Emtek 92013 is a heavy duty plated steel plain bearing hinge in 3-1/2 by 3-1/2 with square corners.

No. Both are plain bearing hinges at the same 3-1/2 inch by 3-1/2 inch leaf size, but the Emtek 92013 is a heavy duty plain bearing hinge in plated steel with square corners, sold in pairs, while the Orca 3514 is a residential plain bearing hinge with 1/4 inch radius corners. The corner alone rules out a drop-in swap in an existing mortise. Emtek's residential-duty plain bearing counterpart is the 91013.

Going up in size and bearing type both help. The Emtek 94013 is a heavy duty ball bearing hinge that stays at 3-1/2 inch by 3-1/2 inch with square corners in plated steel, so the leaf size does not change. If the frame allows a larger leaf, the Delaney RH45xx is a 4 inch by 4 inch bulk residential exterior hinge with 5/8 inch radius corners, and the Don-Jo HWBB84545 is a heavy weight full mortise ball bearing hinge at 4-1/2 inch by 4-1/2 inch. Larger leaves need a wider mortise cut in both door and jamb.

The Orca 3514 covers the 3.5 inch by 3.5 inch openings with 1/4 inch radius corners in nine finishes including satin nickel, oil-rubbed bronze, satin chrome, bright brass and painted black. For the 4 inch openings, Delaney offers the RH40xx at 4 inch by 4 inch in 5/8 inch radius and square, and the RH45xx at 4 inch by 4 inch for exterior use in 5/8 inch radius. Confirm the corner cut on each door group before you settle on one part per size, since the radius differs between these families.

They are close in intent and differ in corner and pack. Both are steel plain bearing residential hinges; the Ives 1010RP has square corners and ships as a set of three at a medium duty rating in the Ives 1000 series. The Orca 3514 is a zinc alloy plain bearing residential hinge at 3.5 inch by 3.5 inch with 1/4 inch radius corners. Order by the corner the existing mortise was routed for.

No. The 3514 is a full mortise hinge with symmetrical leaves, so one hinge works on a left hand or right hand door. The only thing you pick is finish. That makes it easy to stock a single part across a whole building rather than splitting inventory by hand.
