The LFES1 Hanging Shelf can be mounted to systems constructed from 50 mm or 75 mm XE Construction Rails, such as Thorlabs' LFE1220(W) Enclosure Frames or Laminar Flow Enclosures. The shelf panel is slotted to improve airflow for mounted equipment and to preserve laminar flow within laminar flow enclosures. To mount the shelf, the top-bar of the shelf's hanging frame can be connected two adjacent T-slots in a 50 mm or 75 mm rail using the included mounting hardware. The shelf features 403.0 mm of vertical space from the shelf surface to the top of the mounting cross bars, and the height can be adjusted by swapping out the included vertical hanging bars with 25 mm rail extrusions of a different length. For additional shelving space, multiple hanging shelf units can be stacked, as shown in the image to the right.

  • The second moment of area, also known as the area moment of inertia, of a beam is a physical property that represents the beam's ability to resist bending under load. This property takes into account the distribution of material and its distance from the specified axis.
