ABSTRACT:
Disclosed is a device used to set twist angles. The device include a set plate which is supported at one end and a protractor plate at a second end. The hose is placed in position atop the two supports and the hose placed on top of the supports with couplers at each end. The user then clamps the first coupler in a horizontal position pointing toward one of two sides of the set plate. This is used as a reference from which a twist angle may be set at the other side of the tool. The other side of the tool includes a protractor in such a way that the elbow can be rotated in position relative to one of two scales. These two scales are color coded such that for acute angles, the user will know to point the first end horizontally in the red (?) direction and for obtuse angles the user will point the coupler in the blue direction. Depending on which color the user selects will match it up and the elbow twist angles will be properly set. The hose is easily unclamped from the device and crimped.
