A multi-positionable tray assembly (20) for mounting within a chassis (10) of a telecommunications panel (100) is disclosed. The multi-positionable tray assembly (20) may include support arm (24) that pivotally supports a tray (22) and that allows the tray assembly (20) to be installed and removed from the chassis (10). The tray (22) and the support arm (24) cooperatively define a cable routing pathway (208) that extends through a pivot axis (A1) defined by the tray and the support arm. To minimize the required depth of the tray (10) and optimize cable routing, the tray (20) can include a cable management structure (102) with a patch panel (104) having a plurality of adapters (108) arranged along a transverse axis (A2), wherein the transverse axis is non-parallel or oblique to a front plane (A4) of the tray.
