External corner for electrical trunking STASIŃSKI NZ 20x14 white, single-piece

External corner for electrical trunking STASIŃSKI NZ 20x14 white, single-piece is a purpose-designed accessory for rectangular cable trunking systems with a 20×14 mm cross-section. It provides a neat, low-profile external corner transition for surface-mounted installations in residential and light commercial environments. The part is supplied as a single-piece molded component in white, compatible with matching trunking channels to create a continuous cable route around external corners.

Advantages

The external corner ensures a clean angular finish with minimal visible joints, improving the appearance of surface-mounted cable runs. Its single-piece construction reduces installation time and avoids the need for additional fasteners at the corner junction. The white finish blends with standard interior fittings and can be painted if required to match the surrounding surface. The component is lightweight and designed to maintain the internal cable space of the trunking system.

Suitable for

• Surface-mounted cable management in homes and apartments
• Light commercial and office installations where neat external corners are needed
• Retrofit projects where existing rectangular trunking of 20×14 mm is used
• Routing low-voltage power, communication and data cables

Key specifications

• Trunking cross-section compatibility: 20 × 14 mm
• Orientation: external (outside) corner
• Material: molded plastic (white finish)
• Delivery form: single-piece component
• Designed for surface-mounted trunking systems

How to use

Position the external corner over the ends of the two trunking runs forming the external angle and press the component into place, ensuring the trunking channels engage fully with the corner profile. If the trunking system requires, secure the trunking runs to the mounting surface before fitting the corner. Confirm that cables are routed correctly within the trunking and that there is no pinching or excessive bending at the corner. If necessary, trim the trunking ends for a flush fit prior to installing the corner piece.

Usage recommendations

Use this external corner with trunking systems that match the 20×14 mm internal profile and avoid installing under mechanical stress or where large-diameter cables would reduce the internal clearance. For best results, combine with compatible clips, connectors and straight runs from the same trunking series to preserve fit and appearance.
