A storage system for inside a Sea-Land shipping container provides at least two hanging brackets, each bracket having a vertical beam with a hook at an upper end portion for releasable engagement with a lashing ring carried on a wall inside the Sea-Land shipping container to depend therefrom adjacent the wall. By compaction of cladding material in a compaction area next to patterns or ridges that are formed in the core material for realizing an optical waveguiding structure, the effective index of refraction of the optical waveguiding structure can be trimmed. The arch tray form fits over the contours of the teeth of the upper jaw or lower jaw from a first molar region through a second molar region. The biasing member biases the contact toward the ink pack in a direction at an angle to a vertical direction. An unlock-all mechanism operates to move the latch to the unlatched position without operation of the actuator.
