As from 1 January 2025, we have transferred the sales and inspection of our lifting keys to Van der Blij B.V. in Oss. They are one-stop shop suppliers when it comes to prefabricated products and lifting technology. We are delighted with this collaboration. For more information, visit https://vanderblij.nl
For the original certificates of lifting keys that you purchased from Leenstra in the past, you can continue to consult our customer portal. For the registration of inspections that you can have carried out by Van der Blij from 1 January, you can visit their certificate portal.
