LFES1 Shelf for LFE Series Enclosure Frames Chapter 1: Introduction
Rev. A, July 8, 2022 Page 1
Chapter 1 Introduction
The LFES1 Shelf has been designed to provide additional storage space within the LFE1220 and LFE1220W
Optical Table Enclosures; it raises controllers and other equipment off the work-surface of the optical table
whilst keeping them accessible. The shelf panel is slotted to improve air flow to equipment mounted on it, and
to assist in the preservation of laminar flow within the enclosure environment. The hanging rails can be
exchanged for any other length of XE25 extrusion to give a different hanging height; simply order four
extrusions of the desired hanging length.

Assembling the Shelf
The LFES1 Shelf is supplied as a preassembled shelf panel, four hanging bars, two mounting bars and all
required fixings and tools.
1. Lay the shelf panel with the silver face down on the table and one corner protruding over the edge.
2. Hold a XE25 Series Hanging Bar under the protruding corner cube.
3. Drop an M6 x 16 mm Socket Screw through the corner cube and screw in to secure the XE rail flush to
the cube (do not fully tighten the screws). Ensure that the lugs on the underside of the corner cube
secure correctly in the holes in the end of the Hanging Bar.
4. Repeat steps 1 and 2 to fit hanging bars to the remaining 3 corners of the shelf.

Fitting the Shelf to the Frame
The LFES1 Shelf can be mounted to any face with Thorlabs XE profile slots. It is recommended that it be
fitted into two side by side parallel slots (e.g. in XE50 series extrusions). All the roof members of an LFE
series enclosure are suitable for this purpose. See Figure 6 for mounting options.
10. Insert an M6 T-nut into the extrusion slot at the approximate intended mounting position for the shelf.
Repeat in the parallel slot and again in the slots at the opposite end of shelf.
11. With two people, hold the shelf up to LFE frame.
12. Fit a small M6 washer to each of the four M6 x 40 mm bolts provided, followed by a large M6 washer,
then pass the bolts (two in each end of the shelf) through the slots in the attachment bars and secure
in the T-nuts fitted at step 10 as shown below. Do not fully tighten the bolts.

13. Slide shelf to desired position.
14. Tighten all four bolts.
