Sudhaus Gravity Latch
Heavy Duty Locking Gravity Gate Latch
The Original Gravity Latch designed by Sudhaus of Germany. This gravity latch allows your container to stay closed when it is tipped over by accident and prevents animals from getting into whatever is in the container. The design allows the latch to open only when it is turned at a certain degree which happens when the waste hauling vehicle comes, lifts up the can and then tilts it to dump.
Gravity latch components are made of plastics and steel components are plated with a zinc finish to allow the latch to last in the toughest applications. Gravity latch available in multiple locking options.
