watertight door dog latch designs fail
to function properly due to the presence
of paint or other debris such as corrosion
products on the
exposed area of a floating bushing.
The corrosion products are formed primarily
from corrosion of a carbon steel sleeve,
which houses the assembly and is welded
to the door.
The DeNOVUS™ Watertight Door
Dog Repair Kit (MACHALT 526) replaces
the prior wax filling and silicone oil
and the addition of an external shield.
The new patented design has dramatically
improved the cyclic corrosion performance
of the water tight door dog latch.
