Deltana CH2020 Cabinet Hinge, 2" x 2", with Ball Tips (Pair)

No, not without recutting. The CH2020 has square corners, so it wants a square cut pocket. Drop it into a mortise that was routed with rounded corners and you get an open gap at each corner with the leaf sitting proud on the radius. Two ways out: square the corners of the existing pocket with a chisel, or buy a radius corner hinge that matches the cut already in the door. It works fine in the other direction, a square corner hinge sets into any hand chiselled square mortise.

The CH2020 is sold by the pair, so one order unit is two hinges, enough for one standard cabinet door. Tall doors are the exception: a full height pantry or a tall wardrobe door normally gets three hinges to keep the stile from bowing, which means ordering two pairs and having one hinge left over. Count your doors, not your hinges, when you place the order.

No. At 2 x 2 inches this is a cabinet hinge, sized for cabinet and furniture doors, and the leaf is far too short to carry a passage door. Interior doors take a 3-1/2 inch butt hinge and exterior or heavier solid core doors take a 4 inch. Use the CH2020 on cabinetry, built ins, and small furniture doors, and buy a full size butt hinge for anything you walk through.

Eleven finishes: PVD Polished Brass, Polished Brass, Unlacquered Brass, Antique Brass, Polished Nickel, Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome, Oil Rubbed Bronze, and Paint Black. Two of those age differently. Unlacquered Brass is bare metal with no coating, so it darkens and patinas with handling, which is the point if you are matching aged brass elsewhere in the room and a problem if you need a kitchen full of doors to still match each other in a year. PVD Polished Brass is a hard vapor deposited coating over the brass and holds its color, so it is the one to specify when a property manager has to replace a single hinge later and wants it to blend.

Solid brass, body and substrate both. That matters in two places. In a bathroom vanity or a kitchen sink base where humidity is constant, a solid brass hinge will not rust out from a scratched plating layer the way a plated steel hinge does. It also means the Unlacquered Brass version can be polished back to bright metal when it patinas, because the color goes all the way through instead of sitting on the surface.

Ball tip finials come standard on the CH2020, nothing to add to the order and no suffix to specify. The ball tip is what you are buying, so if you need a plain flat tip or a decorative finial instead, that is a different hinge rather than an option on this one.

Residential duty. It is the right hinge for apartment and single family cabinetry, built ins, and furniture, including turns on rental unit kitchens. Where it is the wrong call is high cycle commercial millwork: public restroom vanities, nurse station casework, school and hospitality cabinet doors that get pulled hundreds of times a day. For those openings, spec a commercial grade cabinet hinge rated for continuous duty rather than a decorative solid brass one.
