Specially designed screws and nails can be driven through without damaging the guards. So say goodbye to damaged corners. Each plastic corner protector is clear. *NOTE: Not pre-drilled ? Specially designed screw/nails can be driven through these corner guards without damaging the corner guard. Make sure you also grab some of our door jamb protectors.
