Awesome nail hammer for using 1 1/2 long nails for installing A35 Simpson cable ties. A full size nail hammer would not fit, and there was no room to swing the hammer around. It did the job and more. It says it can hold a nail up to 16d but I found that wasn't the case. A 16D nail is just too big to fit in a collar. So if you buy one, plan on nails smaller than 16D.
