I used those latches on half doors I used to make in the 90's. I was using the Eberhard brand. I undecided on the longevity
with 100~150 pounds on a 18" lever over miles of washboards. it seems the fancier I got with latches the more prone to failure.
I still like Kaymar's best. They took a destaco and put it on steroids and used one per arm for extra safety . I'm testing a Southco, tweaked
and on steroids now
If one wants to pull off the use of a slam style latch there are several things to consider!
I spent countless hours when designing mine and to be honest I had my doubts along the way.
On the more traditional latching systems the latch offers some structure to the swing out by clamping down or together,
With the slam latch the biggest hurdle was now the latches only purpose was to simply keep it closed.
On my design there is zero load on the latch!
A dual shear hinge is used to attach the swing arm along with extra enteral gusseting in the bumper, a large uhmw pad is attached on the bottom to support the swing arm on the bumper when closed.
Another issue I ran into was getting the preload on the latch needed to eliminate rattles, arb uses an adjustable bump stop close to the hinge, the problem I found with this design is once the bump stop was ajusted to eliminate rattles it was hard to shut and open the latch!
I had acsess to an arb bumper so I was able to play with it a bit.
My sulition was to add the bump stop close to the hinge and supply shims to fine tune the desired preload. This allows the preload needed to eliminate rattles while not making it difficult to open or close.
My entire family needed to be able to access the rear of the vehicle during our travels so this was a huge driving factor to the design!
My 100 lb 5' wife, 10 and 6 year old sons have no problem opening and closing the swing outs and this was not the case with the clamping latches I have used in the past.
I have had the chance to test my design and abuse it along side many other makes and have hade zero issues, I was pleased to see this design have less movement than others makes!
There were many hurdles and many times I wanted to give up along the way and go with a more traditional latch but worked through the problems and ended up with a design that I'm confident in.
