4Site | Heavy Duty Nylon Cable Tie 370mm x 7.9mm 100 Pack | Black
The 4Site CT370HDB is a heavy-duty black nylon cable tie measuring 370mm long and 7.9mm 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. Made from UV-stabilised nylon, the CT370HDB holds large, heavy cable bundles across indoor and outdoor installations.
Large, heavy cable bundles and exposed runs place more strain on a tie than a thin standard fastener carries, and unstabilised nylon degrades under sustained sunlight. A 7.9mm strap distributes the load of a heavy bundle across a wide contact face, while UV-stabilised nylon resists breakdown in exposed positions. The 370mm length reaches around large groups, grouped conduit, and bulky components. Bundling the run keeps it organised and holds through weather and vibration.
The CT370HDB tensions by hand, so a full run installs quickly without a separate tensioning tool. The 100-pack maintains a heavy-duty supply on site for large indoor and outdoor installations across a project. Because the nylon is UV-stabilised, a single tie covers exposed runs that standard fasteners cannot survive long term. Purchasing cable ties in bulk keeps the consumable cost per installation low on high-volume work.
Features
- Heavy-duty black nylon construction — the moulded one-piece nylon body gives the CT370HDB high holding strength across repeated fastening.
- 370mm x 7.9mm size — a wide, long tie for large and heavy cable bundles, grouped conduit, and bulky components.
- UV-stabilised nylon — resists sunlight breakdown, so the tie suits outdoor and exposed installations.
- 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 CT370HDB in the van or on site.
- Wide 7.9mm strap — spreads holding tension across a heavy bundle rather than biting into a single point.
- Trimmable tail — the excess strap cuts flush with side cutters for a clean finish on a visible run.
- Indoor and outdoor use — the CT370HDB suits electrical, industrial, construction, and data cabling in exposed or protected positions.
- Heavy-duty bundling, not a load rating — sized for large, heavy cable groups, not for suspending loads or structural fixing.
- 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
- Heavy-duty electrical and data cabling — the CT370HDB groups thick cable runs and grouped circuits in demanding installations.
- Outdoor and exposed runs — the UV-stabilised nylon suits cable and conduit in sunlight and weather.
- Industrial and plant wiring — the CT370HDB holds large harnesses and heavier looms during fit-out and maintenance.
- Construction and infrastructure bundling — ties off large cable groups across sites and structures.
- Conduit, hose, and component fastening — secures grouped conduit, hose, and bulky parts in one wrap.
- Workshop and site heavy cable management — keeps large grouped cable and leads tidy on the bench and racking.
The CT370HDB is a heavy-duty bundling tie, not a load-rated fixing for suspending equipment or structural and safety-critical loads. Match the tie length and width to the bundle so the strap seats fully through the head.
