The GKE 78/100 S is an external corner trim from the Niedax product range, specifically designed for use with device channel external corners with a 90° angle. It serves as a cover for the outer corner of the channel and ensures a clean, visually uniform finish for cable management systems. The trim is intended for device channels of types GKA ... S and DKA ... S, which feature a lid opening of 78 mm. The leg length is 100 mm, ensuring the trim fits precisely on channels with corresponding dimensions. The surface of the visible areas is smooth, providing a professional appearance and easy cleaning.

Applications
The external corner trim is used in electrical installations, particularly for cable routing in open channel systems mounted on exterior walls or in areas with visible installations. It is suitable for applications requiring an aesthetic and functional cover for channel corners, such as in commercial or industrial facilities, office buildings, or for the installation of security technology. It is used in conjunction with the corresponding device channel external corners, also offered by Niedax.

Functions and Features in Detail
The trim is made of steel and is strip galvanized in accordance with DIN EN 10346, ensuring high corrosion resistance and long service life. The galvanization protects the material from moisture exposure and extends the component's lifespan. The smooth surface of the visible areas ensures a uniform appearance and facilitates cleaning. The trim is adapted to the external corner of the channel, covering the edges to create a seamless and professional finish.

Technology Explained Simply
The external corner trim is not an electrically conductive component in the sense of an equipotential bonding connection. Equipotential bonding is achieved through separate components, such as the equipotential bonding cable GSLH... in combination with the junction connector GSTA... (for types ...T60, ...T80, ...T100) or GSVA... (for types ...T70, ...T90), or via the equipotential bonding terminal GPK 63. The trim itself is not designed for equipotential bonding, but serves exclusively for visual and mechanical covering.

Compatibility and Accessories
The GKE 78/100 S is specifically designed for device channel external corners with a lid opening of 78 mm and a leg length of 100 mm. These components are not included in the delivery of the external corner trim.

Installation and Mounting
Mounting is done by fitting the trim onto the already installed external corner of the device channel. The trim is slid over the channel edge and locked in place, with the exact mounting instructions corresponding to the respective channel system. It is essential to ensure that the trim fits precisely to the dimensions of the external corner to guarantee a clean finish.

Operational Advantages
The external corner trim provides a clean and professional appearance for visible installations. The strip-galvanized steel construction ensures high mechanical strength and corrosion resistance. The smooth surface facilitates cleaning and ensures a uniform appearance. Use in conjunction with the corresponding channel systems enables quick and precise installation, reducing installation time. VDE certification confirms compliance with relevant safety standards.
