David Edelstein, founder of Triple E Ltd. trained at LAMDA as a stage manager. He was a member of the stage management team at the National Theatre when it opened in 1976. After many years in technical theatre, David decided that if he was going to work unsocial hours, he wanted it to be for his own business. He began by manufacturing the pin-hinge. The pin-hinge won the ABTT product of the year award and set the company on its future path. Triple E Limited is now a specialist manufacturer of track and scenery systems and since 1998 has designed, manufactured and installed variable acoustic systems around the world that can roll up, track into storage pockets, lift up into the ceiling or just disappear! This is a growing area where no two jobs are ever the same but the team at Triple E are always ready for the challenge. David is a former Chairman of the ABTT.
