Apart from plastic housings, Spelsberg also produces aluminium housings. Aluminium housings are suitable for both indoor and outdoor use. Products of the ALR series are sold as empty housings or equipped with clamps. The housing equipment varies between screwed clamps and block clamps. Clamps up to 4mm² can be used. With IK09, the Spelsberg aluminium housings are certified for extremely high shock resistance. An external hinge set is available as an accessory for converting the housing cover into a hinged door. For single wall mounting, Spelsberg has an external lug set in the range.
