Similar to the model 45, the model 50C uses 1-1/4" PowercleatŪ nails to nail 1/2" and 3/8" tongue and groove flooring. The model 50C is designed to nail flooring without splitting the tongue or damaging the floor surface. One mallet blow drives PowercleatsŪ into tongue and groove flooring at a perfect 45° angle, while countersinking the nail to the proper depth. This nailer allows you to reduce your nailing time to an absolute minimum with its 100 nail holding capacity, one blow operation and no jamming mechanism.
