Stainless Steel Enclosures & Feeder Pillars
Feeder Pillars & Enclosures
The RB range of external electrical enclosures form a part of the Ritherdon range of Feeder Pillars and was initially developed with the street lighting and highways industries in mind; however, their highly flexible, modular design means they are suitable as enclosures for protecting electrical and/or electronic equipment in the most inhospitable external environments (fabricated from stainless steel as standard).

Powder coated at no extra cost (available for all grades of stainless steel 4003, 304 and 316). Standard, 4003 grade of stainless steel is always powder coated to provide the best performance and quality finish. If left unpainted, the 4003 grade of stainless steel develops a patina, soft staining of the material. It won’t rust, however, this is not the finish we like for our product so we always powder coated all our enclosures made from our standard 4003 grade of stainless steel.
