Can Spelsberg enclosures be mounted onto round poles?

Short answer

Our enclosures can be mounted onto round poles using our MSS mast clamp set together with the SRS screw clamp set. The SRS metal band is fastened to the pole and the MSS attaches to the rear of the enclosure, which reduces installation time and secures the enclosure against twisting once installed. The sets fit enclosures of different sizes and poles with diameters ranging from 60 to 210 mm, and the galvanised and stainless steel used gives advanced corrosion protection for a long service life.

Our industrial and outdoor enclosures can be mounted onto round poles. To support this, we offer a mast clamp set, known as MSS, used in conjunction with the SRS screw clamp set. The SRS metal band is fastened to the pole, while the MSS attaches easily to the rear of the enclosure. The set-up can also be coupled with design plates as rear covers for additional protection. Choosing this kit reduces installation time and secures the enclosure against twisting once installed.

Electrical enclosures are often designed with built-in mounting points positioned outside their sealed area, so the structure can be attached directly to flat walls or similar surfaces. There may be situations, though, where an enclosure needs to be mounted onto an irregular fixing such as a round pole. To set up a robust assembly, it is important to use solutions that fit the perimeter of the surface in your intended application.

The solution fits enclosures of different sizes as well as poles with diameters ranging from 60 to 210 mm, offering maximum flexibility. The galvanised and stainless steel used for the sets also delivers advanced corrosion protection, giving durability and a long equipment service life.
