Deltana solid brass cabinet hinges come in an array of fine finishes with ball tip finials as standard, so this CH3020U3-UNL model provides a polished brass look that matches traditional hardware lines while giving doors a finished, decorative pin detail. As a full mortise hinge, it sits into the cabinet and door mortises, allowing the leafs to recess into the wood and keep the hardware largely out of sight during normal use. The hinge measures 3 by 2 inches, giving a compact profile that suits cabinet doors where a smaller hinge footprint is preferred for layout or face-frame proportions. Being part of Deltana semi-concealed hinges, it supports applications where the hinge body is mostly hidden yet still allows visible ball tip finials at the knuckle. This combination of solid brass material, polished brass finish, and full mortise construction makes the hinge suitable for cabinets where appearance and traditional detailing matter alongside function.
The mounting type listed as full mortise means this hinge is designed to sit flush with the wood once the mortise is cut, so door edges close against the cabinet without interference from the leaves while maintaining a controlled gap at the hinge side. The screw-on description ties directly to the use of #7 x 3/4 inch wood screws, so the installer can fasten the hinge through its 6 holes directly into wood frames and doors using standard driving tools. The 3 by 2 inch size sets the leaf dimensions, which influences how much material must be removed for the mortise and how the hinge positions on narrower or wider stiles. With square corners specified, mortising can be done with straight-edged chisels or suitable bits, avoiding the extra step of rounding corners to match the hinge outline. Together, these details support predictable fitting across cabinet runs where repeatable hinge placement is important.
This hinge is categorized under hinges, semi-concealed face-frame hinges, and full mortise hinges, so it suits cabinet projects where most of the hinge body is recessed yet some knuckle detail remains visible along the door edge. The 3 by 2 inch size aligns with cabinet-scale work rather than full-size entry doors, keeping the proportions appropriate for face-frame or frameless casework where smaller hardware is preferred. Because the corners are square, it matches installations where mortises are cut with square profiles, which is common in shops using jigs or hand tools set up for straight-corner recesses. Being a solid brass hinge with a polished brass unlacquered finish, it fits cabinetry where brass hardware is part of the design, allowing the metal to present a classic brass appearance as part of the visible hinge knuckle and ball tip finials.
The hinge thickness of .093 inches establishes a consistent mortise depth, so repeat cuts at this depth across multiple doors produce the same seating of the leaves and help maintain uniform reveals. The 6-hole hinge pattern offers multiple screw points along both leaves, which spreads load into the wood and assists in holding alignment after doors are hung and cycled in normal use. With #7 x 3/4 inch wood screws specified, the fastening is sized for typical cabinet material thicknesses, so bite occurs within the door and frame stock without extending excessively beyond the mounting surface. The solid brass construction contributes to the weight and feel of the hinge, which supports a stable knuckle for cabinet doors that open and close repeatedly throughout daily use. Ball tip finials are standard on this hinge, adding a finished detail at each end of the knuckle that coordinates with other traditionally styled cabinet hardware in the same polished brass family.
The CH3020U3-UNL is a Deltana solid brass cabinet hinge classified as a semi-concealed full mortise hinge, so most of the hinge is recessed while the knuckle and ball tips remain visible.
The full mortise mounting recesses both leaves into the door and cabinet edges, allowing the door to close flush to the cabinet while maintaining a controlled clearance at the hinge side.
This Deltana full mortise cabinet hinge is listed as 3 by 2 inches, giving it a compact leaf size suited to cabinet doors rather than larger architectural doors.
The square corners mean hinge mortises match a straight-edged outline, so recesses can be cut with square chisels or bits and do not require rounding to fit the hinge leaves.
This hinge lists #7 x 3/4 inch wood screws, so the fastening length is suited to standard cabinet door and frame thicknesses while providing adequate grip in the wood.
The CH3020U3-UNL is a solid brass hinge with a polished brass unlacquered finish, providing a traditional brass appearance that coordinates with other brass cabinet hardware.
The Deltana full mortise cabinet hinge CH3020U3-UNL combines a 3 by 2 inch size, square corners, and .093 inch thick solid brass leaves, so it serves cabinet work where a semi-concealed hinge with visible ball tip finials is desired. With 6 hinge holes and #7 x 3/4 inch wood screws specified, it offers a fastening pattern and screw size appropriate to typical cabinet materials and door scales. For cabinet projects calling for a polished brass unlacquered look in a full mortise configuration, this hinge aligns the mounting details, proportions, and finish into one part number that can be used consistently across a run of doors.
