Corner External Fitting TTPLAST 10821 for Electrical Trunking 60x40

Corner External Fitting TTPLAST 10821 for Electrical Trunking 60x40 is an exterior right-angle accessory designed to join two runs of 60x40 mm trunking while maintaining a neat, protective enclosure for cables. The fitting provides an outward corner transition that aligns with the profile of 60x40 cable ducts, ensuring continuous mechanical protection and a clean installation line for visible or semi-concealed wiring routes in homes, offices, and light industrial spaces.

Advantages

This corner external fitting offers precise dimensional compatibility with 60x40 electrical trunking, enabling fast, repeatable assembly without on-site trimming. Its form preserves cable bend radius at the corner and reduces exposure of conductors to mechanical wear. The component simplifies alignment of trunking runs at right angles, supporting tidy cable management and consistent aesthetic appearance along walls and ceilings.

Suitable for

• Forming exterior 90° corners on 60x40 mm cable trunking systems
• Residential and commercial interior wiring routes with visible trunking
• Light industrial environments where surface-mounted cable protection is required
• Retrofit or new installations using matching 60x40 ducting

Key specifications

• Compatibility: designed for 60x40 mm rectangular electrical trunking profiles
• Orientation: external (outside) 90° corner fitting
• Material: durable polymer suitable for indoor electrical installations
• Finish: smooth surface for easy cleaning and paint adhesion if required
• Installation type: snap-fit or screw-fixed depending on trunking system allowances

How to use

Position the external corner fitting at the junction of two 60x40 trunking runs so that the profiles align with the fitting’s internal contours. If required by the trunking system, secure the fitting with the recommended fasteners or snap it into place along the flanges. Route cables through the trunking keeping within allowable fill limits, then close trunking covers to retain cables and maintain mechanical protection. Verify that the corner does not pinch cables and adjust cable routing to preserve minimum bend radii.

Usage recommendations

Use this fitting only with compatible 60x40 trunking components. Confirm that cable fill and bend radius requirements are met before final assembly. For installations in areas subject to impact or moisture, consider using appropriately rated trunking and supplementary sealing or mechanical protection as required by local electrical standards.
