The "2-hole strain relief" is called a cable gland. T&B makes a line that includes 2-hole, 3-hole, 4-hole etc. The part numbers all begin with CC-NPT-*. The 2-hole gland is CC-NPT-12-G-2. You can find the complete selection on the last page of this PDF: http://tnblnx3.tnb.com/emAlbum/albums//tc_us/tc_1_ltnonmettalicflex.pdf
Be aware the diameter of the wires (USE or PV-wire) that you're running through the gland and make sure you order a part that has the right size holes. I like to run my #6 copper EGC through a gland or cord grip as well. The T&B cable glands are not UV resistant, so you don't want to use them where exposed to sunlight (i.e. keep the Soladeck under the array). I've got a collection of UV-resistant cable glands but I can't remember the manufacturer. The problem with those is that they aren't UL listed. If it's not one problem, it's another... The manufacturer of the Soladeck is RSTC Enterprises: http://www.rstcenterprises.com/pdf/soladeck_brochure.pdf I spoke with them a while back when I was getting sorted out with cable glands and the guy I talked to claimed he was working on getting a line of cable glands to sell with the Soladeck. I haven't seen this from any of the suppliers however.

I feel that one must not rely on the foam lid gasket to sufficiently "clamp" the power leads. That just seems like asking Murphy to impose the Law. The conductor for grounding the metal array parts can just exit through a drilled hole in the box with no strain clamp, because there's a metal loop that this wire can first loop through to give some tug prevention.

It seems that the intent is to use cord grips in the south end of the box, but I just saw another installation where the wires just came directly in through the space at the south end. Seems like the foam is included to keep bugs out rather than provide strain relief to those incoming conductors, so I guess I'm just looking for a reality check here. Thanks and happy Thanksgiving!
