Abstract: A longitudinally movable compressor unit for supporting documents in a file drawer. The compressor unit has a document contacting plate extending transversely of the file drawer. A channel extends the width of the plate and has open ends which generally align with longitudinally-extending channels formed in the side walls of the file drawer. A latch extends in and between the channel in the compressor plate and a respective side wall channel at each of the open ends. Each latch has a lug receivable in an aperture on the sidewall channel to selectively latch the compressor unit. A spring or resilient finger is positioned on the latch to bias the latch downwardly to secure the lug in the aperture.
