Roof coil nails any diffrence

Internally they are the same, however the rnd has a semi clear cover to see the coil nails in the cannister (could be other differences but use same nail). There is a difference between brands of nails. Check with local code for required length and type (galvanized , stainless etc). Make sure that the wire that binds the nails together is not too strong and stiff. Some coils have soft copper that works quite nicely and others use a stiff steel wire that tends to pull at the coil and leaves a stiff piece of wire in front of the first nail preventing good alignment to driver. If you are going to depend on your nailer for daily work, order and have in stock upper bumper and cylinder seal. These parts will fail quite quickly. Other parts tend to hold up pretty well. Good luck
