A fiber optic telecommunications device includes a frame defining a right vertical support and a left vertical support. A chassis is mounted to the right and left vertical supports, wherein the chassis is configured to pivot about a pivot axis that is defined by one of the right and left vertical supports. A plurality of modules are mounted on the chassis, each of the modules slidable on the chassis along a direction extending between the right and left vertical supports, wherein the chassis is configured to pivot about a plane parallel to the sliding direction of the modules, each module defining fiber optic connection locations.
