4Site | Nylon Cable Tie 300mm x 4.8mm 100 Pack | Black
The 4Site CT300B is a black nylon cable tie measuring 300mm long and 4.8mm wide, supplied in a pack of 100. The tie is a moulded one-piece design with an internal pawl that grips the toothed strap for one-way tensioning. The CT300B is a heavy-duty size, holding large cable runs, conduit groups, and bulky components.
Large cable runs, grouped conduit, and bulky components pull apart when nothing secures them across a tray, panel, or plant frame, producing a disorganised install. A 300mm tie reaches around large bundles that shorter ties cannot enclose. The 4.8mm strap carries the extra tension a bigger group needs without slipping loose. Grouping the run during installation keeps it organised and simplifies later inspection and maintenance.
The CT300B tensions by hand, so a full run installs quickly without a separate tensioning tool. The 100-pack maintains a working supply on site for repeated bundling across a larger job. At 300mm the ties suit industrial, construction, and automotive runs rather than thin flex groups. Purchasing cable ties in bulk keeps the consumable cost per installation low on high-volume work.
Features
- Black nylon construction — the moulded one-piece nylon body gives the CT300B consistent grip across repeated fastening tasks.
- 300mm x 4.8mm size — a heavy-duty tie for large cable runs, conduit groups, and bulky components.
- Internal pawl ratchet — the toothed strap locks one way against an internal pawl, holding tension once pulled up.
- Hand-applied, no tools — feed the tail, pull, and the tie self-locks, so a run goes on without a tensioning tool.
- 100-pack supply — a bulk count that keeps a working stock of the CT300B in the van or on site.
- Heavy-duty size — suited to large bundles and conduit groups, not a load-rated fixing for structural loads.
- Long 300mm strap — reaches around thick cable groups, grouped conduit, and larger components in one wrap.
- Trimmable tail — the excess strap cuts flush with side cutters for a clean finish on a visible run.
- Industrial and general cable management — the CT300B groups electrical, construction, and automotive wiring across larger jobs.
- Permanent once seated — the tie holds closed under tension and is removed by cutting the strap, not by release.
- Consistent bulk pack — uniform ties across the 100-pack keep fit-off speed steady on high-volume work.
Where to use
- Large electrical installations — the CT300B groups thick cable runs and grouped circuits in commercial and industrial boards.
- Conduit and pipe support — bundles grouped conduit, pipe, and trunking along a run or frame.
- Industrial and plant wiring — the CT300B holds machinery harnesses and heavier looms during fit-out and maintenance.
- Construction site cable management — ties off temporary and permanent cable runs on site.
- Automotive and machinery harnesses — secures larger looms and accessory leads on vehicles and plant.
- Workshop and warehouse maintenance — keeps grouped cable, hose, and leads tidy on the bench and racking.
The CT300B is a heavy-duty tie but is not a load-rated fixing for structural or safety-critical loads. It is intended for general indoor and protected cable management, so confirm suitability before any outdoor or UV-exposed installation. Match the tie length to the bundle so the strap seats fully through the head and holds tension.
