FASTENING: A new series of Corrosion-Resistant Pull-Down Latches from All Metric Small Parts (aMsp) is designed for various types of boxes and transportation equipment. Because springs are used, a tightening force is applied when the latch is closed. Since the latch is made of stainless steel it has excellent corrosion resistance. The holes for a padlock are on the side, preserving the appearance even when there is no lock. 3-D CAD models are available for download.
