Wiska WIB 16 — Circular Surface Sealed Junction Box IP44, 4 x M20 Cones, Thermoplastic, 83 × 44 mm

The Wiska WIB 16 is a compact, robust surface-mounted junction box designed for organising and protecting electrical cable connections in light-industrial or sheltered environments. Constructed from durable thermoplastic in a light-grey finish (RAL 7035), this enclosure offers a simple and reliable housing for joining cables or terminating circuits while providing basic protection against dust and water spray — making it suitable for garages, workshops, utility spaces, and other dry or semi-exposed installations. 

This model features four M20 cone entries, allowing flexibility when routing multiple cables into the box. The coated thermoplastic material is glow wire tested to 650 °C and has high impact resilience, ensuring reliable performance under mechanical and thermal stress. Easy access and an accessible internal volume make installation and maintenance straightforward and installer-friendly. 

With operating temperature tolerance from –25 °C to +85 °C and installation-safe limits between –5 °C and +60 °C, the WIB 16 is designed to perform reliably in a wide range of ambient conditions. Its IP44 protection class offers effective defence against splashing water and solid objects over 1 mm — ideal when full watertight sealing isn’t necessary.
