Colors in Line Art Drawings:

  • Red – 2 felt marks on each side of the ALEX Add-on Unit for a total of 4 felt marks for lining up
  • Green – Where you drill through metal in the STRENGTHENER, 4 times, and wood in the ALEX Add-on Unit 24 times.
    • Blue – 8 Existing wood screw holes in the PARTICLEBOARD Jerker shelf

IMPORTANT! Before working on the real thing try, drilling and threading with a tap on some test materials first.


First, unbolt a shelf from your desk. Next, unscrew the eight wood screws holding the steel STRENGTHENER to the PARTICLEBOARD shelf. Keep these screws!

Next, line up the assembled ALEX Add-on Unit, upside-down, and flush with the front of the PARTICLEBOARD shelf so you can mark the locations of the existing wood screw holes on both of the ALEX’s sides with red felt.

Mark on the ALEX’s sides, where the outermost pair of holes are on the PARTICLEBOARD, for a total of four marks. Two on the left, and two on the right.

Now line up the marks on the left Where holes need to be drilled and tapped on the Jerker shelf's metallic strengthenerand right on the ALEX’s sides, with the STRENGTHENER’s holes. Make sure distances X and Y are the same or you will have a crooked set of drawers.

Now drill four small holes into the STRENGTHENER first and then through the ALEX’s top right after, not stopping. These four small metal holes need to be threaded with a tap to receive bolts. Be sure to keep these four holes hidden inside the drawers.

Then, re-drill the the ALEX’s top slightly larger so you have room to to push the bolt through wood to the metal thread without resistance.

Next, push a bolt through the Alex’s top and thread it into the metal STRENGTHENER. Repeat this step each time, so as to keep all the holes perfectly aligned.

Here we have the Alex attached to the STRENGTHENER with four black short threaded bolts. Now we need to drill eight holes through the ALEX so we can re-attach the drawers with the STRENGTHENER to the Jerker’s PARTICLEBOARD shelf.
