Black cable ties are one of those things that end up on every job, in every van, and somehow never quite where you left them. These nylon self-locking ties are available in fourteen sizes ranging from a compact 100 x 2.5mm all the way up to a substantial 1020 x 9.0mm, so whether you are bundling a handful of data cables behind a panel or strapping conduit runs together on a plant installation, there is a size that fits without doubling back on itself or going slack.
The black colouring is not just for appearances. UV stabilised black nylon offers meaningfully better resistance to sunlight degradation than natural ties, which makes these a sensible choice for outdoor installations, plant rooms, cable trays running near rooflights, or any situation where ties will be exposed to daylight for extended periods. Natural white ties in the same conditions will eventually become brittle and snap without much warning, which is not ideal when you find out six months after the job.
Where Black Cable Ties Work Hardest
On the electrical side, these are the default choice for panel wiring, consumer unit dressing, and armoured cable identification. Mechanical and HVAC trades use the larger sizes for securing insulation, fixing flexible duct, and organising hydraulic hose runs. The 290 x 7.6mm and 370 x 4.8mm sizes are particularly useful for general securing work where a smaller tie would not have the pull strength and a larger one would be overkill.
Choosing the Right Width and Length
Length determines the maximum bundle diameter you can close the tie around. Width determines the locking strength and how much load the tail can take before the head fails. For anything carrying real mechanical load, the 7.6mm and 9.0mm wide ties are the right choice. The narrower 2.5mm and 3.6mm sizes are fine for light cable management where neatness matters more than grip force.
Sold in packs of 100, these black cable ties represent decent value for everyday trade use. Buying across several sizes at once keeps the van stocked and the callbacks down.
Pro Tip: When fitting cable ties in cold conditions, warm a handful in your pocket first as nylon becomes noticeably more brittle below about 5 degrees C and the tails can snap clean off mid-tighten.
Black cable ties are used across electrical installation, data cabling, mechanical services, HVAC, and general site work. Electricians use them for panel dressing, containment filling, and bundling SWA tails. Data and AV installers use the finer sizes to keep structured cabling tidy in cabinets and above ceilings. The larger sizes handle outdoor securing jobs, cable tray organisation, and fixing flexible conduit runs on commercial fitouts. Anywhere cables need to stay put and look organised, these are doing the job.

Key Properties
UV stabilised black nylon
Self-locking ratchet head
100 ties per pack
Suitable for outdoor use
Range of widths for different load ratings
Standard temperature range for nylon ties
Not suitable for: Not suitable for applications requiring releasable or reusable fixings. These are single-use self-locking ties and cannot be undone without cutting.
Select the size that gives you a snug close around the bundle without the tail running out before the head locks. Feed the tail through the head, pull firm and steady rather than yanking, and trim flush with a side cutter. For outdoor use, orient the locking head away from direct rainfall pooling where possible.
Select the correct size for your bundle diameter and required holding strength
Loop the tie around the cable bundle with the locking head on the outside
Feed the pointed tail through the locking head in the correct direction
Pull the tail firmly and evenly until the ratchet clicks tight against the bundle
Trim the excess tail flush with the head using a pair of side cutters or snips
Are these black cable ties UV resistant?
Yes. The black colouring in nylon cable ties typically indicates UV stabilisation, which significantly improves resistance to sunlight degradation compared to natural or white ties. They are a suitable choice for outdoor installations and any application with regular daylight exposure.
How do I know which size to use?
The length determines the maximum bundle diameter the tie will close around, and the width affects the locking strength. For light cable management use the 2.5mm to 3.6mm wide ties. For anything carrying mechanical load or larger bundles, step up to the 7.6mm or 9.0mm wide options. When in doubt, go one size up.
How many ties come in a pack?
Each pack contains 100 cable ties. The same pack quantity applies across all sizes in this range.
These cable ties are manufactured from nylon 66, a polyamide material with good tensile strength and resistance to fuels, oils, and moderate chemical exposure. The self-locking pawl mechanism provides a secure one-way grip when tightened. Black pigmentation provides UV stabilisation, extending the service life in outdoor or exposed installations compared to natural nylon alternatives.
