Reinforced poly attaches to the work platform. Here it is unrolled from the ground and allowed to billow in the wind so that a strong gust will blow the poly rather than topple the scaffold. The scaffold must be tied to the structure or guyed down when enclosed. Here you see the Overhead Protection System used as an enclosure on our older 4-board heavy-Duty scaffold system. “Doors” are cut and rolled up when landing materials. Another view of roof poly. Non-Stop Heavy-Duty on a roof with the Overhead Protection components and reinforced poly. This user built a “basement” under the work platform for his heaters. A side view of the “basement” above. Angle view. Underside.
