But I still don't care for that GFF door latch. ;D
This is one of the stumbling blocks and biggest problem I have with the tube doors out on the market.
1) They are located behind your butt. Fine for the double jointed Chinese Contortionist in the family.
2) They are gravity controlled. The weight of the latch arm keeps the door closed. From looking at the other designs, one good bump in the right direction and your door flys open. (unless there is something in the design I'm not seeing)
I had a hood fly open at 65mhp once. Sucked butt. Every old car since then gets hood pins. Door opening wouldn't be as bad, would still suck.
Solution... something with a spring or locking mechanisim. I thought about snagging the lock mechanism from the stock door, but I didn't want to bastardize them any. = home depot spring and "L" bracket. %) ?:?
