RGB Ex

These Ex approved cable and pipe transits are used in high-risk land-based Ex e and Ex tb environments to minimize danger by preventing fire, water, gas, chemicals and other hazards substances.

RGB Ex transit is casted into a concrete wall or floor. It is manufactured from a 60x60x6 mm angle bar.

Technical specifications

RGB Ex sizes

The standard transit is made of an angle bar 60x60x6 mm, in mild steel, stainless steel or aluminium. The mild steel transits are supplied with two types of surface finish, primer or galvanized. The internal width is always 120.5 ± 0.5.

The standard height varies with the sizes - numbered 2, 4, 6 or 8, which give heights of 100, 159, 218 and 276 respectively.

Correct and safe installations

To achieve the highest standard of safety, a cable or pipe transit must be installed correctly. As there are many different types of frame – which may be either welded, bolted or glued into position – and insert block, it is essential that installers known when to use the most appropriate installation method.
