Eventually the screen door will get walked through, or kicked, and will need repair. Fortunately, there is enough screen on each roll (each side) to go completely across the opening, which leaves much extra material when closing the screen to the midway point on the 400.
The screen door is manufactured by Genius Retractable Screen Systems. The manual for the Milano 200 used in the 400 trawler can be had by clicking here. A manual for the screen replacement can be had by clicking here.
If you would like to attempt fixing your screen as I did, just read the article below to get started.
The first this first thing to do is remove the curtain rod and trim panel(s) . This is a real good time to have the drapes cleaned and repressed.
Now you have good access to the top rail track.
Next you need to find the screws holding the top and bottom tracks in place. These are the only screws holding the screen door assembly in place. There are no screws in the screen rollup assemblies.
After you have removed all the screws the whole assembly will come loose and you will need another set of hands to handle the whole thing. It gets very flimsy and the plastic parts holding the parts togeter can be broken easily. Below you can see where the plastic tongue on the rollup assembly and the screen pull is parted from the top track.
Now bring the parts somewhere where there is a nice big table or bench to work on. Pull out the bad section of screen till you get to good undamaged screen. Tuck a rag in the roll up assembly to keep it from retracting back in.
This is what the ends on the pull and rollup assemblies look like on the bench.
The plastic cap on the pull section will need to come off to allow the screen bead to be slid out. Carefully pryoff the end caps with a knife blade prying a bit on each side to work it out. Just for you convenience before you take things apart, I have added a picture of the cross section of the pull.
I couldn't find a piece of bead the right size to wrap the screen around and feed back into the track, so I used part of the original bead. Remove the bead from the damaged screen with a good pair of shears. Be carefull not to damage it, as you will use this piece to wrap the screen around and feed back into the pull track. You can also cut the screen parallel to the edge pull edge at what ever point you need to get rid of the damaged section at this time.
Next you need to prepare the end of the bead track on the pull to accept the screen and bead. It will be a snug fit and the screen will snag on the sharp edges if not prepared properly. Take a small file and start tapering the opening on one end of the pull to make pulling the screen and bead possible. Polish the edges smooth. The better the job you do here, the less trouble you will have pulling the screen back into the track. Below is a sample of the filed edges before polishing with emery cloth or sand paper.
At this point I stopped taking pictures. My full attention was getting the screen back into the pull track. This is a good time to get a couple of buddies over to help. After the edges are polished smooth, wrap the screen around the bead you cut off earlier so it overlaps the screen by a half inch or so. Don't worry about how much overlap there is because you will trim this back later to neaten the job up. One person will be pulling the screen through while another will be feeding the screen and bead in from the end. Using a little lubricant in the track helps. There will be more resistance as more of the screen enters the track. By the time you are finished, it may take the effort of three people to get it all feed in. Once that is done, trim the excess and replace the plastic end cap. Now its ready to be reinstalled in the boat!
