Narva 56581 P Clip 4.3mm Plastic 100-Pack

Keep your wiring installations clean and secure with Narva 56581 P Clips — the workshop staple for professional cable management in automotive, marine, and 4WD applications.

Product Overview

The Narva 56581 is a 4.3mm internal diameter P-clip designed for securing cables, wiring looms, hoses, and light tubing to body panels, chassis rails, and mounting surfaces. Manufactured from durable black plastic, these clips provide vibration-resistant cable retention without the sharp edges or corrosion issues of metal alternatives. The 4.3mm ID suits common automotive cable gauges including light-duty speaker wire, LED wiring, sensor cables, and brake lines. Supplied in a 100-piece pack, they're ideal for workshop stock, mobile installers, auto electricians, and DIY enthusiasts tackling headunit installs, lighting upgrades, or dual-battery setups. Backed by Narva's one-year warranty and proven across decades of Australian automotive use.

Features & Benefits

4.3mm Precision Fit — Internal diameter is optimised for common automotive wiring including 16-18 gauge speaker cable, LED strip power leads, sensor wiring, and vacuum lines, providing secure retention without crushing delicate conductors.

100-Piece Workshop Pack — Bulk quantity keeps professional installers stocked for multiple jobs, eliminating mid-install parts runs and ensuring consistent cable management across fleet vehicles or repeat customer work.

Non-Corrosive Plastic Construction — Black nylon-type material resists salt spray, fuel vapours, and battery acid better than metal clips, making it ideal for engine bays, underbody installations, and marine environments where rust destroys steel alternatives.

Vibration-Resistant Retention — P-clip design clamps cables firmly against mounting surfaces, preventing chafing and movement fatigue even on corrugated dirt roads, rough seas, or high-vibration diesel engines.

Universal Mounting Compatibility — Single mounting hole accepts self-tapping screws, pop rivets, or machine screws, allowing quick installation on sheet metal, plastic panels, fibreglass, and wooden substrates common in custom builds.

Frequently Asked Questions

What size cables will these clips hold?  They're designed for cables and hoses with external diameters up to approximately 4mm, including typical 16-18 gauge automotive wire, LED strip leads, and small vacuum/fuel lines.

Can I use these under the bonnet? Yes — the plastic material resists heat better than rubber and won't corrode like metal clips. Keep them away from direct exhaust manifold contact or extreme heat zones above 100°C.

How do I install P-clips? Drill a pilot hole in your mounting surface, position the cable in the clip, align the clip's mounting hole, and secure with a self-tapping screw, pop rivet, or machine screw depending on substrate.

Will these hold up on corrugated roads? Absolutely — the P-clip design clamps cables firmly to prevent movement. They're standard in 4WD auxiliary wiring and caravan installations where vibration is constant.

Why plastic instead of metal clips? Plastic won't corrode in marine or underbody environments, doesn't conduct electricity (preventing accidental shorts), and won't damage cable insulation through sharp edges like some metal clips can.
