This is essentially a ratcheting box-end wrench that opens up to surround the fastener — so you don’t have to worry about slipping off it. Think of it as a “super-flare-wrench.”
They come in both standard handle and square-drive versions as well as sets, and they claim a 30-degree ratchet rotation, which seems too large to brag about, considering that GearWrench offers a 5-degree rotation. Of course, GearWrench doesn’t offer this type of head, though.
One last note… Cooper Tools gonna sue someone.
