The 21F1 black wrappable cable protection sleeving is designed to insulate and protect cables operating at elevated temperatures. With an inner diameter of 12 mm (Φ12), it wraps securely around cable bundles and individual conductors without requiring disassembly of the wiring.

It is sold per metre, allowing installers to cut exactly the length required for each application. The -30 to +250 °C operating temperature range covers the demands of ovens, lighting fixtures, relay wiring, and industrial control panels alike.
