Stainless Steel Mounting Frame

Ex op pr applications require mechanical protection of the splice tray and fibres, which is provided by use of a stainless steel mounting frame. An acrylic cover and cable trunking (if the enclosure size permits) add further protection.

The frame can also be used for safe area, Ex op is and Ex op sh applications. Frame dimensions shown below are typical and may vary depending on the application.
