OBO BETTERMANN 129 TB M50 SW Divisible Conduit End Sleeve M50 Polyethylene Black

Sharp, unprotected edges at the end of corrugated conduits can abrade cable insulation over time, leading to premature failure and safety hazards. The OBO BETTERMANN 129 TB M50 SW divisible conduit end sleeve provides a smooth, snap-on termination that shields cables from mechanical stress at the conduit exit, ensuring long-term reliability in industrial and commercial installations.

Who is it for

Electricians, panel builders, and maintenance teams who need a fast, reliable way to finish off corrugated conduit runs. Its divisible design makes it especially useful for retrofits where cables are already in place, eliminating the need to disconnect or re-route existing wiring.

Main features

• Divisible (split) construction allows installation over existing cable bundles without disconnecting.
• Tool-free push-in assembly speeds up installation on M50 metric threads.
• Made from halogen-free, UV-resistant polyethylene for long-term durability indoors and outdoors.
• Flame-retardant material meets common electrical installation safety requirements.
• Provides strain relief and edge protection up to IP65 depending on conduit and seal.
