A small part that finishes the whole runEvery aluminum LED extrusion has two raw ends, and those raw ends are the first thing the eye lands on. The finishing end cap #49 closes that opening so the profile looks intentional, like a piece of trim rather than a cut length of metal. It also does real mechanical work: it holds the diffuser and the LED tape in position at the end of the run, keeps dust and debris from settling on the strip, and protects the tape from fingers, brooms, vacuum heads and anything else that brushes past a toe kick or a shelf edge. Sold as one unit, so you buy exactly the count your project needs — typically two per continuous section, or one per end where runs meet.
Fit and compatibilityEnd caps are profile-specific. The #49 is shaped for the channel it belongs to, and it will not seat properly on a different profile family, so the rule is simple: match the cap number to the extrusion number. Because profiles come in several sizes and styles — recessed, surface-mount, corner, deep, shallow — always confirm the shape and dimensions of your channel before ordering. Solid caps close a run completely; caps with a knockout or an opening let the power lead exit at the feed end. Most clean installs use one open cap where the wire comes in and solid caps everywhere else. If you're working with a different system, the
finishing end cap #11 (no hole) and the
finishing end cap #11 (with hole) cover profile #11, while flexible neon runs are closed with dedicated caps such as the
flex neon endcap 6x6 (without hole) or the
flex neon endcap side view.
Installation, step by stepCut the profile and the diffuser squarely first — a crooked cut is the number one reason a cap sits proud. Deburr the edge with a file or a deburring tool so the cap seats flush against the metal. Dry-fit the cap, then press it into place. For permanent installations, or any run that will be handled, bumped or cleaned regularly, add a small dab of adhesive or a fastener where the profile allows. At the feed end, route the wire through the cap opening before closing it so the connection is never pinched or stressed. A quick check before the diffuser goes back on saves a lot of grief later: make sure the tape is seated, the lead has slack, and nothing is trapped under the cap.
Where it earns its keepUnder-cabinet lighting is the classic application — the cap hides the cut end right at eye level above a countertop. Toe kicks and stair nosings get caps on both ends so the extrusion doesn't collect crumbs or catch a shoe. Cove and ceiling details rely on them to keep long perimeter runs reading as a single unbroken line. In commercial work, think retail shelving and display cases, reception desks, bar fronts, restaurant millwork, closet systems and workshop benches. In Canadian homes, finished basements, walk-in closets and kitchen renovations are where these caps quietly do the most work, and contractors usually keep a handful of each profile number in the van because a missing cap can stall a walkthrough.
Good to know before you orderThis listing is for one finishing end cap, model LCENDCAP-STAND-49, for profile #49. Count your ends before checkout — a U-shaped cove detail with four separate sections needs eight caps, not two — and order a couple of spares so a future extension or a replaced diffuser doesn't send you back to the order page. Pair your caps with the matching channel, diffuser and mounting clips at the same time so everything arrives together and the install runs in one visit instead of two.
