W.AG Funktion + Design offers clever features that can be optionally used with selected case sizes. For example, HEAVY and JAZZ cases can be optimised with intermediate plates that make the interior of the case even more efficient to use. The WAG-HEAVY series scores points with a case lock that is used as anti-theft protection and a trolley system that enables the case to be moved ergonomically on two wheels, especially with heavy case contents.
On request, lid holders can be fitted to the TWIST and HEAVY series to keep the top shell of the case reliably open. This is a popular option that is often used for service cases or sample cases.
