Question:

I leave my trailer parked outside year-round. How does this latch hold up in the weather?

Owen, the 45" trailer door latch # M343FR is zinc-plated steel, so it’s built to resist rust even in snow and rain. For trailers parked outside long-term, a quick squirt of dry lube on the rods every now and then helps keep things moving.

Do you tarp or cover your trailer, or is it completely exposed?

And for other northern folks - how have your latches held up through harsh winters?
