D-216 Is a Set of Two Automotive Tension Wrenches
Picking automotive locks is not as straight forward as picking pin tumbler locks. It's often very hard to find a tension wrench that will properly engage the cylinder and keep it under control. The reason for this is double fold. One - auto door locks are always under fairly stiff spring tension and they fight you. Two - the spring activated dust shutter. This makes it hard for tension wrenches.
The D-216 is just what we've needed. Two tension tools in the set and both are adjustable thanks to sliding components that can be reset and locked with the tightening of a screw. Good to have a set of these.
