Schwinn 6K378 C cap is the plastic rectangular left and right end cap set for a C channel, so each channel termination can match the channel profile and close off the run at both ends. This Schwinn Hardware part is identified as Manufacturer Part # 59275 and is described as C-CAP RECT LFT/RGT FOR C-CHANNEL,BLACK, which ties it directly to C channel applications where a black finish is required. The caps are 2-7/8 in (73 mm) long, giving a defined finished length that matches common channel runs at a cabinet or wall. Because these parts are plastic end caps, they create a finished termination when the C channel butts against the inside of a cabinet or a wall surface, which keeps the open extrusion end from remaining exposed. The web description notes that these plastic end caps give the channel a finished termination at that butt point, so the channel installation can visually stop cleanly at the cabinet interior or wall.
This Schwinn Hardware C channel cap set is defined as C-CAP RECT LFT/RGT FOR C-CHANNEL,BLACK, so it is shaped specifically to work with a C channel extrusion profile where the channel meets cabinet or wall surfaces. The 2-7/8 in (73 mm) long body of each cap indicates how far along the channel the termination will extend, which helps align the cap length with the cabinet interior depth or the wall intersection. Because these parts are plastic end caps, they sit at the channel end and provide that finished termination when the channel butts against the inside of a cabinet or a wall, keeping the open C channel geometry from showing at the stop point. This defined left and right set layout aids consistent orientation when planning mirrored or opposing cabinet runs.
The web description states that these plastic end caps give the channel a finished termination when butting up against the inside of a cabinet or wall, so their primary use is at the point where a C channel reaches an interior cabinet panel or a room wall surface. The C-CAP RECT LFT/RGT FOR C-CHANNEL,BLACK designation indicates they are intended for a C channel profile, which makes them suitable anywhere that C channel runs end at solid surfaces in cabinetry or similar installations. The black color called out in the product name and SAP description allows these caps to visually blend with black channels or darker casework, supporting a continuous look from the running length of the channel right through to the end point at the cabinet or wall.
Because this item is part of the Schwinn 6K378 Series and categorized under Handles and Pulls in Decorative Hardware & Moldings, it fits into hardware layouts where a C channel functions as a decorative or functional profile, and the terminations must meet cabinetry cleanly. The 2-7/8 in (73 mm) length provides a consistent termination segment at every end of the C channel, which simplifies repeating the same visual detail across multiple cabinet bays or wall intersections. As a designated rectangular left and right set, each cap aligns to its respective side of the run, so opposing terminations can mirror each other, maintaining symmetry wherever parallel C channel lines meet cabinets or walls.
The specific SAP description C-CAP RECT LFT/RGT FOR C-CHANNEL,BLACK confirms that the geometry and color are defined, which supports repeatable results when standardizing terminations across a project that uses the same C channel profile. Since the web description clearly identifies these as plastic end caps, their material behavior at the channel end is predictable in normal cabinet environments, helping the termination keep its intended form at the interface with the cabinet interior or wall. The 2-7/8 in (73 mm) length called out in the product name gives installers a precise dimension to work into layout drawings, so the point where the C channel stops and the cap finishes against the cabinet or wall can be located consistently.
The fact that the product is listed as a Schwinn 6K378 Series 2-7/8 in (73 mm) Long Black C Cap Rectangular Set (R & L) ties all of these elements together into one matched pair, which supports using the same part number 59275 wherever that combination of C channel termination, black finish, and rectangular left and right configuration is needed. Because these plastic end caps are described as giving the channel a finished termination at the cabinet or wall, using the defined left/right set and fixed length helps produce uniform end conditions, reducing visual variation between cabinet bays that share the same C channel detail.
The Schwinn 6K378 C cap set is a plastic left and right rectangular end cap pair for a C channel, providing a finished termination where the channel meets the inside of a cabinet or a wall.
The Schwinn 59275 black C channel caps are 2-7/8 in (73 mm) long, so each cap covers that length of the channel end where it terminates at a cabinet or wall surface.
These C channel end caps are plastic, which allows them to create a finished termination at the end of the channel where it butts against the inside of a cabinet or a wall.
These rectangular C caps are used at the point where a C channel butts against the inside of a cabinet or a wall, finishing the open end of the channel at that surface.
Left and right set means this product provides one cap for each side of the C channel run, so both ends can terminate in a matched rectangular form at cabinet or wall intersections.
The black color of this C-CAP RECT LFT/RGT FOR C-CHANNEL helps the termination blend with black channels or darker cabinet and wall finishes, keeping the end detail visually consistent.
This Schwinn 6K378 Series 2-7/8 in (73 mm) Long Black C Cap Rectangular Set (R & L) is defined as C-CAP RECT LFT/RGT FOR C-CHANNEL,BLACK, so it directly targets C channel terminations at cabinet or wall intersections. The web description notes that these plastic end caps give the channel a finished termination when butting up against the inside of a cabinet or wall, which ties their role clearly to that end condition. When a project calls for a black plastic left and right rectangular C channel cap with a 2-7/8 in (73 mm) length, this Schwinn Hardware part number 59275 offers a consistent way to finish each channel end against cabinets or walls.
