OBO Bettermann Inner Corner GS-SI70130RW Pure White Symmetrical 6277240

Routing cables around a 90-degree bend inside a GS-SI trunking run often forces installers to cut, mitre, or improvise with straight sections, which weakens the enclosure and leaves edges that can damage insulation. This inner corner eliminates that problem by providing a purpose-moulded, symmetrical bend that matches the 130 x 70 mm channel exactly, so the cable path stays clean and protected through the turn.

Who is it for

Electricians and panel builders who install OBO Bettermann GS-SI surface trunking in offices, workshops, or commercial buildings and need a reliable internal corner for neat 90-degree cable routing.

Main features

• Symmetrical design allows use in either direction, simplifying stock and installation.
• Clip-on / push-fit mounting onto GS-SI trunking without tools or adhesives.
• Made from PVC with self-extinguishing properties for basic flame retardance.
• Pure white (RAL 9010) finish blends with standard trunking for a consistent look.
• Maintains the same internal cross-section as the trunking, preventing cable pinch or bend radius violations.
