Managing corners and crosses is one of the biggest problems structure installers and hirers have to face. Dado is the answer. It is devised around a six-faced die-cast cube and may be put together in multifarious ways leaving the user conplete freedom. Whith Dado it is no longer necessary to plan the purchase of the set standard corners: all you have to do is invest in a few basic modules which you can arrange as needed. Each individual junction is assembled with reinforced tubes without welding. The connection between DADO and the trusses is the quick-fit type, with special steel half-spigots. Their assembly and alignement is made easy with an assembly template.
