FLEX NEON ENDCAP 6X6 - (WITHOUT HOLE)

What this end cap is for
Flexible neon is a cut-to-length product. You unroll it, measure against the wall, sign or cove, and cut at the marked cut points. That cut leaves the silicone body open, exposing the internal end of the strip. A finishing end cap closes that opening, protects the cut end and gives the run a clean, intentional termination instead of a raw edge. This particular model is the solid, no-hole version for the 6x6 square profile, meaning it is used wherever the run simply ends and no wire needs to exit.

Construction and fit
The cap is moulded to match a square 6x6 neon flex profile, so the finished end stays flush and discreet — important when the termination is visible at eye level on a sign or behind a bar. It is not a universal cap: the geometry matters, and a cap that matches the profile is what makes the seal reliable. Because it has no hole, it pairs naturally with the drilled version installed at the opposite end, where the power lead passes through. On a typical run you use one of each: hole at the feed end, solid cap at the far end.

Installation and sealing
This cap is designed to be used with a suitable silicone adhesive, which bonds the cap to the profile and creates a sealed joint. Cut only at the marked cut points, then wipe the end clean and dry before applying adhesive. Push the cap on firmly, make sure adhesive squeezes evenly around the seam, and let it cure fully before powering up or exposing the run to weather. A well sealed end is what allows a run to keep its wet-location or damp-location rating once it has been modified, which matters for outdoor signs, soffits and humid interiors such as pool rooms and commercial kitchens. Skipping the cure time is the most common reason a field-cut end later fails.

Where it gets used
Sign shops use these caps on channel letters and backlit logos; renovators use them on cove ceilings, stair details, kitchen toe kicks and feature walls; small businesses use them on storefront perimeter lines, gym walls and garage accent lighting. In Canadian exterior work — soffits, canopies, patio structures — a sealed end is not cosmetic, it is what keeps water and road salt spray out of the cut. Keeping a handful of spare caps in the van is simply smart, because layouts get adjusted on site more often than not.

Compatible accessories
Several accessory options let you finish straight runs, corners and feed points consistently across a whole project. For the 6x6 profile, the matching pass-through cap is the Flex neon end cap 6x6 with hole. If your project mixes profiles, the 3x6 family covers the slimmer format with the Flex neon end cap 3x6 without hole and the Flex neon end cap 3x6 with hole. Side-emitting and top-emitting layouts are covered by the Flex neon end cap side view without hole. Always confirm the profile of your neon flex before ordering, and buy caps in the same quantity as the cuts your drawing shows.
