A fiber optic cabinet has internal aligned guides on opposite sides of an axis opening. A splice tray has a planar tray base with a tray axis orthogonal to the base. The base has a peripheral edge sized for opposite portions of the peripheral edge to be slidably engaged with opposing ones of the aligned cabinet guides. The tray base is slidably received within the aligned guides regardless of a rotational position of the tray base about the tray axis. A fiber pathway guide is carried on the tray base for receiving a wound amount of optical fiber on the guide as the tray base is rotated about the tray axis.
