Deltana solid brass cabinet hinges come in an array of fine finishes with ball tip finials as standard, so this CH3020U15A hinge provides a finished look while supporting the cabinet door pivot. The hinge size of 3 x 2 inches sets a compact footprint that suits smaller cabinet doors where a full-size door hinge would be oversized, giving a proportional look while managing the door load in typical cabinet applications. The semi-concealed hinge style keeps part of the hardware out of view, which helps maintain clean cabinet lines while still leaving enough of the hinge visible for alignment and adjustment tasks during installation. As a product in the semi-concealed hinges class, it fits jobs where a traditional surface hinge would be visually heavy yet a fully concealed hinge is not required, bridging that gap for many cabinet layouts.
The mounting type listed as full mortise means the CH3020U15A hinge is designed to sit into matching recesses in the cabinet and the door, so the leaves close together neatly and keep gaps tight when the door is shut. Square corners support straight, non-rounded mortising, which aligns with common router jigs or hand tools that cut rectangular pockets without corner radiusing, simplifying layout for installers who prefer square patterns. The wood screw specification of #7 x 3/4 inch ties the hinge directly to typical cabinet-grade materials, giving bite into the face frame or case material without over-penetrating thinner components. Six holes in the hinge provide multiple screw positions, so each leaf can be secured along its length and help the door stay aligned through repeated use.
The product name Deltana Free Swinging Full Mortise Hinges, Screw-on Antique Nickel - CH3020U15A identifies this hinge as a free swinging style, so the barrel allows the cabinet door to move through its arc without built-in closing mechanisms, which suits installations where door motion is controlled by user operation or separate components. As part of the semi-concealed hinges product class, it places one leaf inside the cabinet structure while leaving the barrel and part of the leaf visible, which keeps the hinge accessible for alignment while reducing the visual footprint on face frames. The 3 x 2 inch SAP description dimension, listed as 3 x 2 hinge, antique nickel, positions this hinge for doors where a compact size is needed to fit narrow stiles or smaller doors, helping avoid interference with adjacent doors or drawer fronts in tight cabinet runs. The antique nickel finish described in the product information coordinates with other antique nickel items in the same project, allowing designers and installers to maintain a consistent look from hinges to other cabinet hardware. Deltana solid brass cabinet hinges being made from solid brass means the base material is brass rather than a thin steel stamping, which gives the hinge body substance for edge mortising on cabinet doors. Ball tip finials as standard provide a finished cap at the top and bottom of the hinge barrel, adding a decorative point that also visually signals hinge orientation when laying out multiple hinges on a tall cabinet door.
The full mortise mounting type lets installers rely on the hinge leaf thickness of 0.093 inch when setting up mortise depth, so repeat cuts produce consistent flush mounting and reduce the chance of proud or recessed leaves that affect door reveal lines. Square corners pair with that full mortise design to keep layout straightforward; straight chisel or router passes define the pocket, and the hinge edges match that geometry so alignment depends mainly on accurate measurements, not complex shaping. The wood screw specification of #7 x 3/4 inch wood screw focuses screw engagement within the cabinet material, giving installers a predictable pilot hole size and depth for each hinge position in wood substrates. Six holes hinge layout spreads those #7 x 3/4 inch screws along the leaf, allowing the hinge to resist twisting forces when doors are pulled from different angles. The Deltana Enterprises, Inc. brand association links this hinge to Deltana's line of solid brass cabinet hinges, so installers working across multiple cabinets can use the same look and basic geometry where ball tip finials and fine finishes are desired. The product classification as hinges in the semi-concealed face-frame hinges and full mortise hinges category describes its role in projects that call for mortised, partially hidden hardware rather than overlay surface hinges, guiding cabinet layout decisions toward that installation style.
The CH3020U15A is a Deltana solid brass cabinet hinge in the semi-concealed hinges product class, so it serves as a partially hidden hinge for cabinet doors using a full mortise layout.
The full mortise mounting type means each hinge leaf sits in a recessed pocket in the cabinet and door, so the leaves close flush and help maintain tight reveals on the finished cabinet.
The SAP description lists the hinge as 3 x 2 inch, so installers can size mortises and door layouts around that footprint when planning hinge spacing and edge clearances.
The square corners match rectangular mortises, so routing or chiseling can follow straight cuts, which simplifies hinge pocket preparation on cabinet frames and doors.
The hinge thickness is 0.093 inch, giving the leaf enough material to sit solidly in the mortise and support the door without a flimsy feel at the pivot points.
The wood screw specification is #7 x 3/4 inch, so fasteners of that size match the hinge holes and provide appropriate grip in typical cabinet-grade wood materials.
The Deltana full mortise cabinet hinge CH3020U15A combines solid brass construction, a 3 x 2 inch footprint, and an antique nickel finish, so it fits projects calling for semi-concealed hinges that match other antique nickel components. With square corners, six screw holes, and #7 x 3/4 inch wood screw specification, it supports straightforward mortising and fastening steps on cabinet doors and frames. For cabinet jobs built around solid brass hardware and ball tip finials as standard, this hinge provides a consistent look and a known set of dimensions to plan around from the first layout to the final door swing.
