Don't have pictures, but here's a description of how it works:
The D&S Screen used toggle clamps to hold the screen to the door.
The top, bottom and two sides were a standard heavy-duty screen frame.
The bottom frame was reinforced with a flat aluminum plate going the width of the frame and maybe 2.5 -3" high from the bottom. The toggle clamps were attached to the bottom plate with the rectangular slots pointing down.
The toggle clamps are similar to
these
There was a threaded bolt that was welded to a small square plate on one side. The threaded side had a couple of nuts and washers with bent tabs to hold it into the retangular slot on the toggle clamp.
When you toggled the clamp, the square plate from the threaded clamp would apply pressure to the bottom half of the TM door.
