Roof bracket scaffolds
Scaffold brackets shall be constructed to fit the pitch of the roof and shall provide a level support for the platform.
Brackets (including those provided with pointed metal projections) shall be anchored in place by nails unless it is impractical to use nails.
When nails are not used, brackets shall be secured in place with first-grade manila rope of at least three-fourth inch (1.9 cm) diameter, or equivalent.
