Designed for heavy duty tasks. All metal design. Built solid and tough. When you need something that is guaranteed not to break, this is the angle adapter you need.

Make sure when you change angles with the adapter that when you screw it back together, that the teeth in the center interlock with one another. Do not tighten if the teeth are on the top of one another as this could cause the teeth to strip the gears. This is very important!!  And it is the only way to ruin this device.
