Deltana solid brass cabinet hinges come in an array of fine finishes with ball tip finials as standard, so this hinge supports traditional cabinet styling while keeping the moving parts compact at the door edge. The hinge is described as a semi-concealed hinge in the full mortise hinge category, which lets the leaves sit flush into the cabinet and door, helping keep gaps tight and alignment consistent across a run of doors. The 2 x 2 hinge size noted in the description relates to small cabinet doors, which helps match the hinge scale to face frames and light door weights typically found in cabinetry. The polished brass unlacquered description means the solid brass surface is presented without a protective lacquer, so the metal is exposed directly and can show the natural brass character in the installed space.
The mounting type listed is full mortise, so the hinge leaves are designed to sit flush into routed or chiseled pockets in both the cabinet and the door, which helps keep the hinge barrel aligned on the door edge. The corners are specified as square, and that shape supports mortising with straight-edged layout and cleanup, which is useful when routing multiple identical pockets on cabinets. The wood screw noted is #7 x 3/4 inch, so the screw sizing is matched to typical cabinet stile thickness, helping the hinge grip the material while staying within a standard cabinet door and frame build-up.
This product is listed as a Deltana free swinging full mortise hinge in the semi-concealed hinges class, so it is oriented to cabinet applications where most of the hardware sits within the mortise and the knuckle remains visible. The 2 x 2 hinge dimension in the description lines up with cabinet door proportions rather than large entry doors, which suits smaller door widths typically found in kitchen and furniture projects. The polished brass unlacquered wording in the SAP description ties to solid brass construction with a polished brass appearance, so the hinge visually suits other brass components on the installation. Ball tip finials are standard on these cabinet hinges, and that decorative tip at the hinge ends gives the visible knuckle a finished look when doors are open or when hinge barrels remain in view on the cabinet face.
The full mortise mounting type allows both leaves to sit level with the surrounding wood, so once the mortises are cut to the .093 inch hinge thickness, the door edge can close to a consistent reveal without the leaf riding proud. Square corners on the hinge simplify layout because the pocket edges follow straight lines, so once a jig is dialed in, an installer can cut the same recess repeatedly and have the hinge sit tightly. The six holes specified in the hinge provide spaced fastening points along the leaf, so the #7 x 3/4 inch wood screws grip both rails and stiles where available, helping stabilize the hinge under regular cabinet door use. The solid brass material noted in the web description means the hinge knuckle and leaves are formed from brass, so the polished brass unlacquered surface reads as true brass at the door edge, supporting a consistent look with other brass cabinet components.
The CH2020U3-UNL is described as a Deltana free swinging full mortise hinge in the semi-concealed hinges class, so it is intended for mortised cabinet applications where the knuckle remains visible.
The full mortise mounting type means both leaves sit into recesses in the cabinet and door, helping the hinge barrel align on the edge and supporting even reveals on finished cabinets.
The hinge corners are square, so the mortise pocket uses straight-sided cuts and chisel cleanup, which aligns with jigs and methods set up for square-corner hinge layouts.
The .093 inch hinge thickness gives a defined leaf depth, so routing pockets to that depth lets the door sit correctly in the opening without the hinge leaf holding it off the frame.
The wood screw listed as #7 x 3/4 inch matches common cabinet stile thickness, so it fastens the hinge leaf into the wood while staying within typical cabinet door and frame dimensions.
The SAP description notes polished brass unlacquered, so the solid brass surface presents a polished brass look at installation, matching other brass cabinet components visually.
The Deltana solid brass cabinet hinge with part number CH2020U3-UNL combines a 2 x 2 size, full mortise mounting, and square corners, so its proportions and layout suit cabinet door work. The .093 inch thick solid brass leaves and six-hole layout support stable fastening with #7 x 3/4 inch wood screws, which is important for holding small doors on face frames and cases. The polished brass unlacquered description and ball tip finials standard on these hinges establish a finished brass appearance, so this hinge ties in cleanly on projects that use brass hardware throughout.
