Schwinn inner corner 59284 is a plastic corner piece designed for use with aluminum L-channels, so two channel lengths can meet cleanly at an inside corner. The piece matches silver clear anodized finishes, which keeps the transition visually consistent across the run. The corner is 13/16 inch wide, giving a defined, repeatable reference dimension when laying out adjoining channel legs. By fitting the channel sections into this molded part, the corner handles the change of direction while the straight channel legs stay uncut at the meeting point. The plastic construction keeps the part lightweight and easy to handle during layout. This version is identified as 6K399-L and is part of Schwinn Hardware decorative hardware and moldings, so it fits into handle and pull layouts where aluminum L-channels are used for visual or functional edges.
This Schwinn plastic inner corner is built around a straight-cut workflow, where each aluminum L-channel is cut square and then inserted into the molded part. That approach removes miter saw angle setups and keeps repetitive cuts fast when running multiple pieces. The part forms both inner and outer corners, so the installer uses the same basic process whenever the channel turns. Because the silver color matches clear anodized, the transition from channel to corner stays visually close to the original metal, reducing the need for additional trim steps. The 13/16 inch width defines the turn area, which helps when aligning channels with adjacent faces or hardware in decorative hardware and molding layouts.
This inner corner is specified for alu L-channels, so it sits at direction changes in those aluminum profiles rather than along the straight span. In handle and pull concepts or decorative moldings that rely on L-shaped aluminum channels, it occupies the point where two legs meet. The 13/16 inch width sets the physical size of that junction, giving a predictable corner block between adjoining faces or surfaces. Because it handles both inner and outer corners, one style of corner piece can be used around an entire perimeter, whether the channel wraps inside a recess or around an external edge. The silver tone matching clear anodized links it visually to common aluminum finishes, helping the corner read as a continuation of the existing channel trim in installations supplied by Wurth Baer Supply.
The design that allows straight cuts to the channel means every length can be processed with a simple 90-degree cut, so fabricators can standardize their saw setup across a project. Two channel lengths feeding into one corner piece help hold the alignment at the joint, since the molded geometry defines the meeting point instead of relying on perfectly matched miters. Working as both an inner and outer corner reduces part variation, which is useful when stocking components for repeated fixture or cabinet runs. The plastic material keeps the corner easy to handle when adjusting the fit of the aluminum L-channels during dry-fit or final positioning. Matching the silver clear anodized look ties these junctions back into the overall decorative hardware and moldings scheme stocked by Wurth Baer Supply, keeping pulls, trims, and channels visually coordinated.
The Schwinn inner corner 59284 is designed for alu L-channels, so it is used specifically where aluminum L-shaped channels need a formed corner transition.
The corner piece allows a straight cut to the channel, so installers cut the aluminum legs square and rely on the molded part to form the turn, simplifying saw setup.
The plastic corner pieces create a finished inner or outer corner, so the same Schwinn part manages both types of direction changes in the L-channel run.
The silver version of this Schwinn corner matches clear anodized, so it visually aligns with typical aluminum L-channel surface treatments used in trim layouts.
The Schwinn plastic inner corner is 13/16 inch wide, which defines the size of the junction where the two aluminum L-channel lengths meet at the corner.
The manufacturer part number for this Schwinn inner corner is 59284, and it is also identified as 6K399-L within the product naming.
The 6K399-L inner corner, silver, gives aluminum L-channel projects a molded way to form inner or outer turns using straight-cut legs. For decorative hardware and molding work handled through Wurth Baer Supply, this Schwinn Hardware piece supports clean, repeatable corners that visually match clear anodized channel finishes.
