STASIŃSKI NW 20x14 Internal Corner for Electrical Trunking, White

Unlike cutting and bending straight trunking sections—which often leaves uneven seams and weakens cable protection—this precision-moulded internal corner delivers a clean 90° turn inside a wall angle. It matches the 20x14 mm profile exactly, so the finished run looks continuous and professional.

Highlights

• Snap-on installation: no adhesives or screws required; the corner clips firmly onto the trunking base.
• Flame-retardant PVC: self-extinguishing material adds an extra layer of safety in residential and commercial wiring.
• UV-stabilised: resists yellowing and brittleness even when exposed to sunlight, keeping the installation neat over time.
• Impact-resistant construction: withstands minor knocks during installation and everyday use without cracking.
• RoHS compliant and CE certified: meets European safety and environmental standards.

In daily use

Electricians and DIY installers will appreciate how quickly this corner solves the problem of routing cables around internal wall angles. The smooth, semi-gloss white finish blends with standard white trunking, while the internal radius guides cables gently without sharp bends that could damage insulation. Because it is a separate component, you can install the straight trunking sections first and then clip the corner into place—no need to pre-assemble the entire path. The part is lightweight yet durable, and its precise dimensions ensure a snug fit.
