Internal Corner 25×20 mm 90° LHD, Kopos model 8915, cream-white

Kopos internal corner 25×20 mm 90° LHD model 8915 in cream-white is a molded accessory for rectangular cable trunking systems. It fits 25×20 mm cable ducts and provides a clean, right-angle transition for cable runs inside rooms. The piece maintains mechanical protection and visual continuity of the trunking system while allowing cables to follow building corners without exposed wiring.

Advantages

The internal corner is made to match standard 25×20 mm rectangular trunking, offering precise fit and consistent appearance along runs. Its 90° left-hand downward configuration enables orderly routing where an internal corner requires cables to turn and descend. The cream-white finish reduces visual contrast on light-coloured walls and simplifies installation by eliminating need for on-site bending or complex jointing.

Suitable for

• Routing mains and low-voltage cables around internal corners in residential interiors
• Neat installation of data and communication cabling in offices and commercial premises
• Retrofit or surface-mounted wiring where preserving wall finishes is important

Key specifications

• Compatible trunking cross-section: 25×20 mm rectangular profile
• Angle: 90° internal corner, left-hand down orientation
• Material characteristic: molded polymer suitable for trunking systems
• Colour: cream-white to match light interior finishes
• Function: provides mechanical protection and continuous cable routing at corners

How to use

Prepare the trunking runs by cutting the 25×20 mm trunking to length and ensuring end faces are clean. Position the internal corner piece at the junction where the run turns 90° left and descends; slide or clip the trunking ends into the corner component according to the trunking system’s assembly method. Verify cables remain within the trunking profile and secure the assembled trunking to the wall with appropriate fixings. Remove and re-seat the cover if necessary to access or adjust cables.

Usage recommendations

For reliable installation, check compatibility with the specific Kopos 25×20 trunking series and use appropriate fasteners and adhesives for the wall substrate. Avoid forcing oversized cable bundles into the trunking to prevent deformation of the corner piece. Inspect connections periodically to ensure covers remain seated and the routing remains secure.
