    Youngdale Free Swinging 3/8" Inset Pin/Knife Hinge, Screw-on Rubbed Bronze - 4DS-200.RB

    Description

    Youngdale 3/8 Inset Hinge For Semi-Concealed Doors

    Youngdale free swinging 3/8 inset hinge is a semi-concealed pin/knife hinge that supports inset cabinet doors while keeping the hardware largely out of sight from the front. This hinge is part of Youngdale self-locking pin hinges, so the hinge design helps hold the door position during normal operation, which supports consistent door alignment over time. The rubbed bronze finish identifies the 4DS-200.RB variant and provides a darker hardware look that coordinates with similar rubbed bronze components in the project. As a semi-concealed hinge in the pin/knife hinge category, it suits installations where clean frontal appearance matters while still allowing practical access to the hinge during fitting or replacement.

    Key Youngdale Pin Hinge Details For Projects

    • The hinge is described as a 3/8 inset pin hinge, which defines how far the door sits into the cabinet opening and helps match this hinge to doors built for a 3/8 inch inset layout.
    • The hinge is a screw-on rubbed bronze design, so it fastens with screws rather than press-in components, giving the installer a straightforward, mechanical attachment to the door and cabinet.
    • The product is classified as a semi-concealed hinge, meaning much of the hinge is hidden from frontal view, supporting cleaner cabinet lines while keeping hinge geometry accessible from the interior.
    • The hinge is identified as a pin/knife hinge within the hinges category, which signals its slim, interlocking leaf design suited to tight clearances along the cabinet door edge.
    • The manufacturer part number 4DS-200.RB ties this specific rubbed bronze version to Youngdale documentation, helping match replacements on jobs where the same hinge style and finish are already in use.

    Screw-On Door Mounting And Adjustment Details

    The hinge is described as screw-on, so it fastens directly using screws instead of specialized press-fit hardware, giving the installer direct control over positioning during layout. All hinges are stated to use eight #6 x 5/8 inch screws, so each installation point is designed around that screw size and length, which helps standardize drilling and driving steps across a run of doors. The door wings are double slotted for easy door adjustment, so once the hinge is mounted, the elongated slots allow shifting the door position before tightening, which supports fine-tuning reveals and alignment without re-drilling. Together, these details aid in fitting doors accurately within the cabinet opening.

    Using This Semi-Concealed Hinge In Cabinet Work

    Where The Youngdale 4DS-200.RB Hinge Is Applied

    This Youngdale Manufacturing Corporation hinge is described as a free swinging 3/8 inch inset pin/knife hinge, placing it in cabinet or casework layouts where the door sits partially within the face frame or opening. As a semi-concealed hinge, it is intended for situations where the frontal appearance is important and the hinge should not dominate the look, yet interior access to the hinge remains available during fitting or service. The web description states that Youngdale self-locking pin hinges are completely hidden from frontal view if the door edge is a minimum of 7/16 inch thick, so doors built or selected with that edge thickness can conceal the hinge when closed. That hidden-from-front configuration supports projects seeking a clean, uninterrupted face without visible hinge barrels. The rubbed bronze finish helps this specific model coordinate with other rubbed bronze hardware in the installation, maintaining a consistent appearance when doors are open and the hinge is visible from inside.

    Hinge Opening Angles And Face Frame Conditions

    The web description notes specific opening angles tied to door and face frame dimensions, which directly affects door swing and access. It states an opening angle of 135 degrees with 3/4 inch thick double doors on a 3/4 inch face frame, so in that configuration the hinge allows the pair of doors to open wide enough for typical cabinet access while controlling how far they project. It also states an opening angle of 165 degrees with 3/4 inch thick double doors on a 1-1/2 inch face frame, so when used on a deeper face frame with the same door thickness, the hinge geometry supports a larger swing for greater opening clearance. These defined angle and frame combinations help plan cabinet layouts around adjacent walls, appliances, or interior pull-outs. The double slotted door wings, described as providing easy door adjustment, support dialing in those installations so the doors swing to the intended clearances without binding along the frame or against neighboring doors.

    Common Questions About This Youngdale Hinge

    What type of hinge is the Youngdale 4DS-200.RB?

    The Youngdale 4DS-200.RB is a free swinging 3/8 inch inset pin/knife hinge classified as a semi-concealed hinge, so it supports inset doors while keeping most hardware out of frontal view.

    How does the self-locking pin hinge design help in use?

    The Youngdale self-locking pin hinge design helps hold the door position during regular opening and closing, which supports stable alignment and consistent operation over time.

    What door edge thickness hides the hinge from the front?

    The Youngdale self-locking pin hinge is completely hidden from frontal view when the door edge is a minimum of 7/16 inch thick, so doors with that edge thickness can cover the hinge when closed.

    How do the double slotted door wings help adjustment?

    The double slotted door wings allow shifting the door position before tightening screws, which helps fine-tune reveals and alignment without altering the basic hinge mounting points.

    What opening angles can this hinge provide?

    The hinge provides about 135 degrees opening with 3/4 inch double doors on a 3/4 inch face frame, and about 165 degrees opening with 3/4 inch double doors on a 1-1/2 inch face frame.

    What screws are specified for fastening this hinge?

    The Youngdale pin hinge uses eight #6 x 5/8 inch screws, so drilling and driving steps can be planned around that screw size across a run of doors.

    Selecting This 3/8 Inset Hinge For Your Job

    This Youngdale free swinging 3/8 inch inset pin/knife hinge in rubbed bronze combines semi-concealed mounting, defined opening angles, and double slotted door wings to support practical cabinet work. The specified 3/8 inch inset, 7/16 inch minimum door edge for hidden frontal view, and stated 135 and 165 degree opening conditions give clear design parameters when laying out doors and face frames. The screw-on installation using eight #6 x 5/8 inch screws centralizes fastening details so drilling patterns and hardware handling stay consistent from cabinet to cabinet. For projects needing a rubbed bronze semi-concealed hinge with these operating characteristics, this 4DS-200.RB model from Youngdale Manufacturing Corporation aligns directly with those requirements.
