What is a Cable Clamp?

Cable Clamp & Strain Relief Guide for Pendant Lighting

Cable clamps—also known as cord grips, cable retainers, cable glands, or strain reliefs—are essential safety components in pendant lighting. They secure the fabric electrical cord inside ceiling roses and lamp holders, relieving physical tension on the copper terminals so the weight of the pendant shade does not pull the wires free.

Conical vs. Cylindrical Cable Clamp Profiles

Our strain relief cable grips are available in two primary shapes: Conical (tapered) and Cylindrical (straight). Choose your profile based on whether you prefer a minimalist tapered look or a structured metallic finish.

Why are cable clamps required on lamp holders?

Cable clamps thread into the top of lamp holders to grip the outer fabric flex securely. This prevents physical strain on internal electrical screw terminals, maintaining AS/NZS compliance when hanging pendant lamps.

How do cable clamps work inside ceiling roses?

Installed inside or beneath a ceiling rose, the cable grip holds the weight of the hanging light fixture so the electrical connections inside your ceiling junction box remain completely strain-free.

Conical Plastic Strain Relief Clamps

Simple, economical thermoplastic cable grips available in White, Black, and Transparent finishes. Ideal for low-profile mounting on modern minimalist pendant fixtures.

Extended Architectural Metal Cable Clamps

Offered in decorative extended lengths (7 cm and 15 cm) to serve as a visual design feature above lamp holders or below ceiling roses, hiding exposed threads for a premium architectural finish.

Cylindrical Metal & Plastic Cable Clamps

Machined metal and molded plastic cylindrical strain reliefs. Supplied complete with M10 hollow all-thread, retaining washer, and nut for universal installation on 10mm lighting hardware.

What cable diameter range do conical strain relief clamps accommodate?

Conical plastic cable clamps feature a screw-down collet that compresses securely onto fabric cables down to approximately 3 mm in outer diameter.
