Our story
Spelsberg has manufactured enclosures and connection technology for over 120 years.
Spelsberg UK, based in Telford, holds UK stock and runs a bespoke modification service, machining cut-outs, drilling, milling/engraving and printing to order.
Enclosure Answers exists because our technical team kept getting the same practical questions from engineers, panel builders and contractors and the answers weren't written down anywhere public.
So, we publish them. Free, impartial, and signed by the engineer who wrote them.
