OBO Bettermann borne de conexión 2710/25 25mm borne de cruz para conductores redondos y planos (5001226)

Connecting two conductors at a 90° angle in earthing, lightning protection, or potential equalization systems often requires a clamp that can handle both round and flat conductors without compromising conductivity or corrosion resistance. The OBO Bettermann Connection Clamp 2710/25 solves this by providing a robust cross clamp made of hot-dip galvanized steel, designed to securely join a main conductor (round 8–10 mm or flat up to 30 x 3.5 mm) with a round connecting conductor (8–10 mm).

Who is it for

Electricians and installers working on lightning protection and earthing systems in residential, commercial, or industrial buildings will find this clamp essential for creating reliable cross connections between conductors.
