Anchoring Clamp
- Dead-ends LV-ABC bundle by gripping the insulated neutral messenger
- Wedge or bail design — no tools to remove the cable sheath
- For self-supporting and messenger-supported aerial bundled cable
- UV-stabilised glass-reinforced body, stainless bail
- Mechanical holding to 10–16 kN per the messenger size
- Reduced-size body for quick pole-side handling

Application & Installation
Where it is used
The anchoring clamp dead-ends a low-voltage aerial bundled cable (LV-ABC) at terminal and angle poles by gripping the insulated neutral messenger of the bundle. It anchors the run without stripping the cable sheath, holding the bundle's tension while the phase cores remain insulated.
Installation sequence
- Separate the insulated messenger from the bundle at the pole.
- Seat the messenger in the clamp wedge / bail.
- Close the clamp so the wedge self-grips under tension.
- Hook the bail to the pole bracket / dead-end hook.
- Dress the phase cores and connect via piercing connectors.
Buyer’s Guide: Anchoring Clamp
1. What an Anchoring Clamp Does
An anchoring clamp (ABC dead-end / tension clamp) terminates a low-voltage aerial bundled cable by gripping its insulated neutral messenger. It is the LV-ABC equivalent of a conductor dead-end — but it never contacts bare metal, so the cable stays insulated and weatherproof at the termination.
2. Wedge / Self-Gripping Action
The clamp uses a wedge or sprung bail that grips harder as the cable pulls — self-tightening under load. This means fast, tool-light installation and a grip that cannot loosen while the span is in tension.
3. Sizing by Messenger Cross-Section
Select by the messenger conductor size (25–95 mm²), not the overall bundle. The wedge must match the messenger so it grips the load-bearing element correctly; holding runs 10–16 kN across the range.
4. GRP vs Aluminium Body
Glass-reinforced plastic (GRP) bodies are light, fully insulating and UV-stabilised for residential ABC; aluminium bodies suit heavier 4-core bundles and higher holding. Pick by bundle size and exposure.
5. Keeping the Sheath Intact
Because the clamp grips the messenger and not the phase cores, the cable sheath is never cut at the dead-end — preserving insulation and avoiding the water ingress that a stripped termination invites.
6. Pairing With ABC Hardware
The anchoring clamp works with pole brackets, dead-end hooks, suspension clamps and insulation-piercing connectors to build a complete LV-ABC network. Order the matching bracket and connectors for the bundle.
