Every aluminium channel run needs three things the profile itself does not include: a fixing at each end, a clip or bracket every 250-300mm, and a cap to close the cut face. This collection covers those parts, sized to the channel or neon body they sit on rather than a one-size-fits-all bag.
Accessories here are IP20 on their own; outdoor protection comes from the IP67 or IP68 strip or neon inside. Pick the profile first from LED profiles and channels, then match clips and caps to the exact width you have ordered.
