Connected by ambition.

That is our motto at Jacob. But it’s more than just a play on words – it is something we truly believe in. Just like our customers, we expect a lot from our products and services. As an experienced cable gland specialist, we’re used to dealing with tricky challenges.

“That was quick!” is a common refrain at Jacob when we respond – with our renowned speed – to inquiries from customers who have shown an interest in our cable entry systems. We love it when our customers recognize our efforts, as this also demonstrates an appreciation of how important the interplay between product and service is in the industrial sector. And it really is! Even at this stage, the small, unassuming parts of our process chain can play a key role in the end result. But in the same way, almost every application hides beneath its surface unrealized potential. We have made it our objective to identify this potential and enable our customers to leverage it. To do this, we apply all our specialist knowledge as a problem solver in all matters relating to cable entry products.
