Learn more by watching our NLS 30398 | 2 X 16mm Heavy Duty Double Screw Connector video.
The NLS 30684 is a 12mm flat cable clip dimensioned for 2.5mm two core and earth flat cable, supplied in a tub of 5000 clips. Each clip combines an impact-resistant polyethylene body with a zinc plated hardened steel nail, pre-tapped into the clip body ready for installation. The 30684 covers the 12mm clip dimension within the National Light Sources cable clip range, which is also produced in 10mm and 14mm sizes.
Fixing a full house of 2.5mm two core and earth to timber framing consumes clips faster than almost any other electrical consumable on the vehicle. Smaller packages empty partway through a rough-in, and work stops while somebody drives back to the wholesaler. The 5000-clip tub covers an entire domestic installation with capacity remaining, and the 12mm clip dimension corresponds to 2.5mm two core and earth, so the cable seats without compressing the insulation. Anti-droop insulation grips maintain the cable position overhead while the nail penetrates the timber.
Bulk consumables are where installation margin quietly disappears, so purchasing clips by the tub reduces the individual clip cost and removes restocking interruptions. A single 30684 tub travels in the vehicle and supplies consecutive domestic rough-ins without reordering. Single-handed clip-on positioning keeps one hand available for the ladder or the cable while the other delivers the hammer. Stock control stays simple: one clip dimension covers every 2.5mm circuit on the job.
The 30684 is a nail-fixed clip intended for timber. It is not suitable for masonry, concrete or steel stud framing, where the hardened steel nail cannot achieve proper penetration. The 12mm clip is dimensioned for 2.5mm two core and earth only, so it will not retain 1.5mm or 4.0mm flat cable at the correct tension.

"Clips for Days" — Ben
(30398)
It is designed for two 16mm² copper conductors, making it suitable for large-capacity joins in higher-load circuits.
The connector is rated at 63A, allowing it to be used on demanding submains, switchboard feeds and other heavy-duty wiring tasks.
Each conductor is secured by two deep slotted screws, providing a strong mechanical hold and improved contact stability.
No, this connector is intended for copper conductors only.
When joining 16 mm² conductors or when a 63 A-rated, robust mechanical connection is required, particularly in switchboards, submains and other heavy-load circuits.
