This Part mates the Jansjö lamp to Steelworks or other material with holes on 1-inch centers, freeing up desk/workbench space that would otherwise be taken by desk lamp(s). Having the lamps anchored solidly also makes repositioning a one-handed affair.
Instructions
The angle iron on this bench has 0.4" holes for 5/16" bolts. 5/16" was a bit beefy for this little part and I already had a nice-fitting hex-head recess for 1/4" bolts, so I used that. The result is that the bolt fit in the holes is sloppy, but the protrusion in the center of the back of the part engages a 0.4" hole snugly and holds the part in position. The holes are slightly below center to match the alignment of the angle iron and look more aesthetically pleasing. The hole on the end is a somewhat frivolous and not too well thought-out cable grommet so you can feed the Janjsö's power cord through it. Unfortunately there's a switch and a big plug on the cord so to feed it through the hole you need to cut and splice the cable. It's low-voltage so there's not much safety risk, but you do have to get the polarity right since this is after all an LED lamp.

The solution if you do not want to screw the armrests on an Ikea chair
e.g. since they don't fit under your desk. Not mounting the arm-restswill leave some blank nuts which don't look very pretty.

The new slider design is noisier, this is a replication of their older part design which has no wheels.

Slide the piece into the curtain hanger piece and attach with setscrew if it's not snugly fit.
