The pistol grip handle of the Radiarm provides good leverage and a comfortable grip when manipulating light or heavy objects. Radiarm holds the object by firm spring pressure until it is released by a deliberate squeeze of the trigger. The jaws can be locked in fixed position for use on heavy loads by tightening the knurled nut at the pistol grip end. This nut can be rotated by the thumb, and the trigger controlled by the index finger, for one-hand operation.
Serrated jaw ends furnish a sure grip on smaller objects.
