ABSTRACT:
The device used to protect/repair a debris chute is a sheet of material adapted to fit over and between the conical funnel sections of construction debris chute. Two chain segments are attached to the sheet to allow a user to connect the sheet to the two chute support chains, which support the conical funnel sections of a construction debris chute. Each of the chain segments are connected to a clevis, shackle, or bolt for connecting the chain segments to the support chains. The sheet of material is of a suitable material and of suitable size and thickness to properly withstand the impact of falling material that would typically be dropped down a construction debris chute.
