Patented by Jordahl in 1913, one of the most reliable fastening techniques - the anchor channel system with clip or T-head bolts - will celebrate its 100th birthday in three years’ time. Prior to this, Deutsche Kahneisen Gesellschaft mbH (DKG), the manufacturer of Jordahl products, wants to revise the design of this well-proven system and adapt it to new requirements in both European and global markets.
