What this end cap isThis is a single
finishing end cap #90, standard style, with a hole for wire entry. It is the last component of an
aluminum channel system for LED strip lighting, installed at the cut end of the extrusion. Without it you see the raw aluminum edge, the exposed ends of the LED tape and a diffuser that can slide out of its track. With it, the run reads as one continuous line of light with a tidy, deliberate termination — the difference between a job that looks installed and a job that looks improvised.
Construction and fitThe cap is moulded to match the cross-section of the channel it belongs to, which is why it slips on with a friction fit that holds without screws. That snug fit also does real mechanical work: it captures the
diffuser lens at the end of the profile so the lens cannot creep out over time, especially on long horizontal runs or overhead mounting. Finishes are selected to blend with standard extrusions so the termination stays visually discreet. Because it forms a closed end, it also acts as a dust-resistant closure, which matters in workshops, garages and retail displays where airborne dust would otherwise settle inside the channel and dull the diffuser.

Installation and wiringWork in this order: cut and prepare your channel to length, feed the supply wire or driver lead through the opening in the cap, then press the cap onto the end of the extrusion before you secure the profile to the surface. Fixing the channel first and trying to thread the wire afterwards is how installers end up with a pinched conductor or a cap that will not seat. For runs that get handled often, or profiles mounted overhead where gravity works against you, a small dab of adhesive on the inside face of the cap makes the connection permanent. Caps are typically used in pairs — one
with a hole on the supply side and one solid at the far end — so decide where the power enters before drilling or gluing anything.
Compatibility and applicationsEnd caps are
profile-specific: this one is made for the #90 channel and should be matched to that exact extrusion model, not simply to a channel of similar width. Several shapes and styles exist across the channel families, so always confirm the profile number stamped on or listed with your extrusion. Typical projects include
under-cabinet and toe-kick lighting in kitchens, cove and ceiling coffers, floating shelves, reception desks, display cases, backlit signage and bench or task lighting in a shop. If your project mixes profiles, the same logic applies to the
Finishing end cap #11 with hole and its
solid #11 counterpart, while flexible neon runs are terminated with dedicated caps such as the
Flex neon endcap 6x6 with hole or the
Flex neon endcap 3x6 without hole. No additional documentation is listed for this accessory; when in doubt, match the cap to the channel model you already own and order caps in pairs so every run is properly closed at both ends.
