How to Determine the Angle of a Nail Gun

Search the exterior of the box that the nail gun was purchased in. Usually, the angle of the nail gun will be displayed on the box or in the user's manual.

Use your protractor to measure the angle in your nail gun. If you do not have the original packaging or user's manual, a protractor is an excellent tool for measuring angles. Stand the protractor on a level surface with the curve pointing up.

Disconnect all power from the nail gun and unload any nails. Hold the nail gun by the handle. Keep holding the protractor so it stands upright on the table. Press the safety element at the end of the nail gun's barrel flat on the level surface. The barrel should be perpendicular to the level surface.

Observe where the bottom edge of the magazine meets the outer edge of the protractor. The edge of the magazine will line up with a number on the protractor. This number is the angle of your magazine and nail gun.
