    6K399-L Inner Corner, Nickel Color 13/16" Width, Plastic

    Description

    Inner Corner For Alu L-Channels Nickel Use

    inner corner for alu l-channels nickel is a plastic corner piece from Schwinn Hardware that joins two aluminum L-channels at an inside corner, so you get a clean transition where cabinet or furniture channels change direction. The 13/16 inch width gives a defined bearing surface along the corner, which helps keep the aluminum channel lines visually consistent from run to run. The nickel color matches nickel channel installations, so the corner visually blends with surrounding trim instead of drawing attention. Because this part works as a connector between straight channel lengths, it lets you form inside corners while keeping both channel legs straight-cut. That keeps layout simple on site, since you only need square cuts on the aluminum instead of complex corner shaping. In shop or field work, that reduces layout time at each inside corner and keeps results more repeatable on multiple openings.

    Key Corner Piece Details For Channel Runs

    • The plastic corner piece design lets you use straight cuts on both L-channel lengths, which saves layout time and allows quick adjustments when dimensions change slightly during cabinet or fixture installation.
    • Fitting two channel lengths into a single corner piece creates a unified inner corner, so the transition looks consistent across adjoining runs and helps align the visible edges of the aluminum channel.
    • The same plastic corner piece also works for finished outer corners, so a single part number can be used wherever channel runs turn, simplifying planning across a job.
    • Nickel color matches nickel channel use, so the connection line is visually minimized and maintains a continuous metallic look at the corner in cabinetry or millwork.
    • The 13/16 inch width defines how much space the corner occupies at the turn, which supports predictable spacing when laying out cuts on aluminum L-channels in repetitive work.

    Corner Connector Installation And Channel Fit

    This plastic inner corner is designed so two aluminum L-channel lengths fit directly into the piece, which means installers cut the channels straight to length and seat them fully into the connector. That layout keeps the corner geometry controlled by the manufactured piece rather than by field cutting, which supports consistent angles across multiple corners. Because no miter cut is required in the aluminum, work at each corner focuses on accurate measuring and straight cross-cutting only. The 13/16 inch width establishes the space occupied at the joint, so installers can account for that dimension when planning overall channel runs along cabinets or fixtures. With the nickel color aligned to nickel finishes, the corner visually completes the run wherever the L-channel turns inward or outward.

    Using Inner Corner Channel Pieces In Projects

    Where This Plastic Inner Corner Fits Best

    This Schwinn Hardware inner corner is used wherever aluminum L-channels need a finished turn at an inside or outside corner on cabinetry, furniture, or similar work. By accepting two channel lengths into one connector, it lets runs turn through a corner while keeping both legs cut square, which is useful on straight-edged components and panel edges. The 13/16 inch width gives each corner a known footprint, so the part can be planned into drawings and repeated across several identically built cases or fixtures. Nickel color makes it a practical match for nickel-toned channel installations, supporting a uniform look when the channel profiling continues around corners.

    Why These Corner Details Support Clean Results

    The fact that the corner piece is plastic and sized to take two channel lengths means the part sets the angle and alignment, so the finished corner depends less on hand cutting at the jobsite. That can reduce rework where miter cuts would otherwise need fine tuning to close gaps. Using a connector that works for both inner and outer corners simplifies ordering and stocking, since one corner geometry handles both turn directions while still delivering a finished appearance. With the channel entering the piece on both sides, the visible aluminum lines meet at the connector, which helps maintain straight visual lines across door openings, panels, or shelf fronts. The 13/16 inch width also defines a constant reference dimension, which ties corner layout back to a repeatable measurement every time the channel changes direction.
