3. Where bracket fitting position aligns with outer frame steel reinforcement, secure using 3.9mm diameter pan head drill point screws (or specialist equivalent) of an appropriate length. If the bracket fitting position does not align with the outer frame steel reinforcement, secure using 4.8mm diameter pan head drill point screws of an appropriate length.
