Deltana solid brass cabinet hinges are designed as semi-concealed full mortise hinges, so the leaf sits in a mortised pocket and supports a clean, built-in look on face-frame cabinets where a traditional exposed hinge is not desired. The hinge size of 2-1/2 x 2-1/2 inches defines the leaf proportions, which helps match the scale of small to medium cabinet doors in typical woodworking projects. The unlacquered brass finish provides a plain brass surface that can age naturally in service, which matters when matching existing aged brass fittings in a shop, kitchen, or furniture piece. Ball tip finials are standard on these hinges, giving each knuckle a defined end detail that ties in with other ball-tipped hardware on the job. As full mortise hinges, they are suited to applications where a flush fit between door and frame is required for alignment and appearance.
This Deltana full mortise cabinet hinge uses a 2-1/2 x 2-1/2 inch format, so installers can lay out matching mortises on both door and frame to keep margins even along the hinge side. Square corners require mortises that are cut with straight corners, which suits either hand-chiseled pockets or jigs designed for square layouts instead of round router-bit corners. The 0.093 inch hinge thickness establishes how deep to cut the recess, letting the door edge sit flush with the face frame or cabinet side once the leaf is fully seated. As a semi-concealed hinge in the full mortise class, part of the hinge nests into the joinery while leaving the barrel and ball tip finials visible, so the hardware reads as a deliberate design element instead of a surface strap.
This hinge is classified under semi-concealed hinges and full mortise hinges, so it suits face-frame cabinets and furniture doors where part of the hinge is recessed and part remains visible. The 2-1/2 inch by 2-1/2 inch size works well on smaller cabinet doors, where oversized hinges could crowd the stile or rail layout. Being a solid brass cabinet hinge, it aligns with projects using brass knobs, pulls, or catches, keeping metal tone consistent across the installation. The unlacquered brass finish lets the surface follow the room environment and handling over time, which is useful when matching older brass hardware or when a patinated appearance is preferred. Ball tip finials as standard give each hinge barrel a finished profile, which matters on exposed edges such as upper cabinets or furniture cases where the hinge end is in direct view.
The full mortise mounting type defines both the layout and the hinge action, because the leaves sit flush with the wood surfaces and establish a consistent pivot point along the door edge. With square corners, installers can work to a clear rectangular template, which supports repeatable hinge pockets from door to door when producing multiple cabinets or case pieces. The 0.093 inch thick solid brass leaves provide a robust bearing surface around the knuckle, supporting smoother movement under the door weight over time. Six hinge holes allow a regular screw pattern, helping the stile resist twisting forces when doors are opened from the outer edge. The specified #7 x 3/4 inch wood screw sizing aligns the hinge with typical cabinet-frame thicknesses, so the fasteners engage enough material for long-term hold without passing through thinner stock. Together, these Deltana full mortise cabinet hinge details support predictable clearances, reliable swing, and consistent visual alignment across a run of cabinets or furniture doors.
The CH2525U3-UNL is a Deltana solid brass cabinet hinge in the semi-concealed, full mortise hinge class, so it recesses into the wood while leaving the barrel and finials visible.
The hinge measures 2-1/2 inches by 2-1/2 inches, which defines the mortise size and helps match the scale of small to medium cabinet or furniture doors.
The hinge uses unlacquered brass, providing a plain brass surface that can age naturally, which is useful when coordinating with existing aged brass hardware.
The leaves have square corners, so mortises are cut with straight corners, matching chisel work or square templates without needing radiused pocket corners.
The hinge thickness is 0.093 inch, giving each leaf a solid brass section that resists flexing and supports consistent door movement at the pivot.
The hinge uses #7 x 3/4 inch wood screws, matching common cabinet frame thicknesses so the fasteners bite securely into typical stile and door materials.
The CH2525U3-UNL Deltana full mortise cabinet hinge combines 2-1/2 x 2-1/2 inch sizing, 0.093 inch solid brass thickness, and ball tip finials to support both function and appearance on cabinet or furniture doors. The unlacquered brass finish allows the metal to age alongside other brass components in the room, helping projects maintain a consistent look over time. With a full mortise mounting type, square corners, and six screw holes designed for #7 x 3/4 inch wood screws, this hinge offers a defined layout for installers building or updating cabinets that call for semi-concealed brass hardware.
