The Eldon MAS range of mild steel single door wall mounted enclosures are available from Rowse Automation from stock in many different sizes. The Eldon MAS enclosure is well suited to a wide range of applications and industries and is our most popular enclosure. All MAS enclosures have an ingress protection rating of IP66. Ensuring your enclosure has a high IP rating reduces the risk of component failure and the risk of downtime in your system.


Eldon MAS enclosures are manufactured from mild steel in varying thicknesses depending upon the depth and/or size of the enclosure required:

155mm Depth 1.2mm Thickness
210mm or 260mm Depth 1.4mm Thickness
300mm or 400mm Depth or Height/Widths ≥1000mm 1.5mm Thickness


All Eldon enclosures are folded, and seam welded to ensure the most optimum construction. On the rear of the enclosure, four 8.5mm diameter holes are available for wall fixing, with indentations pressed out in 20.4mm diameter x 2mm to allow air circulation around the rear of the enclosure.


The MAS range of enclosures have a single door fitted to the front of the enclosure with an opening of 130o. The door has concealed removable hinges with captive pins; the door can be removed, and the hinges can be mounted for a left or right-hand opening. The door also is fitted with fixing studs to mount the door profiles MMDP if required. To ensure the ingress protection, the door is fitted with an injected one-piece polyurethane gasket.


The Eldon MAS enclosure comes complete with a customised lock with a double-bit for easy opening of the door. The double-bit is a 3mm insert and has a 90o locking/ unlocking movement. For enclosures that are 1000mm high or greater, these are fitted with an espagnolette three-point locking system. The enclosure locks can also be upgraded to change the insert to a keyed lock such as a RONIS Key.

Mounting Plate

The MAS range is available with or without a mounting plate. The mounting plate allows the fixing of components within the enclosure without having to fix directly to the enclosure walls. The mounting plate is fixed onto the enclosure using the M8 press welded studs fitted to the rear of the enclosure. On both the top and bottom of the enclosure, there are holes for cable fixing; the mounting plate is also marked vertically at 10mm intervals for easy horizontal positioning of equipment. For mounting plates, 800mm and above additional strengthening is provided by adding folded edges. The AMG accessory can also be used for positioning the mounting plate to any depth.

Gland Plate

The enclosure is complete with a gland plate opening; this is situated at the far rear of the enclosure on the top or bottom of the enclosure depending upon the orientation. The gland plate is designed to make cable termination into the enclosure easier.


The MAS enclosure complies with an ingress protection of IP66, NEMA Type 4, 12 and 13 and also has an impact rating of IK10. For installations outside it is recommended that a rain hood ARF and 100% polyester paint covering is applied, corrosion resistance must be taken into consideration for this type of installation.

Mild Steel Enclosure Range

Rowse automation stock a wide range of wall mounted mild steel enclosures with a single door, double door and panel versions. All of our mild steel enclosures are epoxy polyester coated in a light grey, RAL 7035 colour.

The mild steel range of enclosures is typically used for indoor applications such as automation and control panels, machine control panels and HVAC systems. The corrosion resistance is guaranteed by salt spray tests conducted internally according to the standard ASTM B117:11.

Our mild steel enclosures have a sturdy cruciform body and are folded from cold pressed sheet steel plate. The edges of the enclosures are folded in the shape of a channel to avoid water stagnating on the seal.

The Eldon Mild steel enclosure range has been designed to comply with all the relevant standards for empty enclosures, IEC 62208 and is regularly audited by the independent laboratory DEKRA that allows Eldon to put the KEMA-KEUR mark into the enclosures. The maximum protection for ingress protection is available for the user and the equipment thanks to the IP ratings of IP55 and IP66 according to IEC 60529 and impact protection of IK10 according to IEC 62262.

All enclosures in the range have UL certification for the USA, CSA for Canada, GOST and EAC for Russia and others, which makes export easier, especially for machine builders.

Eldon enclosures with single doors or panels have a two or three point locking system and double doors using a three-point espagnolette system. All doors come complete with a seamless polyurethane gasket.

Completing the range of Eldon enclosures is a wide range of accessories allowing for any configuration. All enclosure versions are designed around the same platform; therefore the same accessories may be used on all versions, this makes the engineering easier and allows for stock reduction for panel builders. Assembly of the enclosure and accessories can be carried speedily, reducing assembly time and ensuring you remain competitive.

All doors fitted to the Eldon mild steel enclosures open within the out dimensions of the enclosure body. This allows enclosures to be mounted side by side without the doors interfering with each other.

Enclosures can be secured to the wall using bolts, fixed directly through the rear wall of the enclosure or wall mounting brackets. The fixing bolts are protected inside the enclosure with plastic washers, for either mounting method the IP ratings are guaranteed.

Rowse Automation has a wide range of standard sized mild steel enclosures directly from stock. Our stock offering allows us to provide an enclosure to suit most applications ensuring the quickest delivery times.
