What this end cap isThe
finishing end cap #84 is the closure piece for the standard aluminum profile it was shaped for. Sold as a single unit (1X) in the standard, no-hole configuration, it caps the open extremity of an
LED aluminum channel and finishes the assembly of profile, lens and tape light. Installers also call these pieces plugs, closures, caps or
LED strip light end caps; whatever the name, the function is the same — close the opening, protect the components inside and give the fixture a deliberate, finished edge instead of a raw cut.
Build and fitThe cap is made to match the standard profile shape it is designed for, so it seats snugly against the extrusion walls rather than floating loosely on the end. That tight fit does two useful things. First, it holds the
diffuser in position, which keeps the light output even all the way to the end of the run and prevents the lens from creeping out over time as the channel heats and cools. Second, it shields the end of the channel from impact and from dust migrating inside — the kind of everyday abuse a profile takes under a cabinet, along a stair nosing or inside a display case. The solid face, with no hole, is also the cleaner look when the cap is visible at eye level.

Installation and where to use itPlan the ends before you cut. Trim the channel square so the seam between the extrusion and the cap stays tight and invisible from normal viewing distance; a ragged cut is the number one reason a cap looks crooked. Dry-fit the diffuser and the end cap together before final mounting, check that the lens slides fully home, then fix the profile to the surface. If the installation will see vibration or frequent handling — a drawer front, a movable display, a shop counter — a small dab of adhesive on the inside faces keeps the cap firmly in place. Use the no-hole cap at the far end of the run and at both ends of a standalone section; use a version with a hole wherever the power lead or connector has to pass through. Typical projects include
under-cabinet lighting, cove and ceiling details, stair and hallway accents, display shelving, reception desks, closet lighting and other light-commercial millwork, in residential renovations as easily as in small retail or office fit-outs.
Compatibility and related partsChoose the cap that matches your extrusion: this one is for the standard #84 shape. For other profiles in the same family, see the
finishing end cap #11 (no hole) and the
finishing end cap #11 (with hole). If your project also uses
flexible neon, the matching closures are the
flex neon endcap 3x6 (without hole) and the
flex neon endcap 6x6 (without hole). No spec sheet, IES file or video is provided for this accessory; selection is made by profile shape, so measure your extrusion or match it to the profile you ordered, and keep a couple of spare caps on hand for job-site breakage.
