Abstract
A high temperature industrial roof assembly having two refractory bricks with adjacent faces, opposing hanger recesses, a hanger rod extending from the recesses to the top of the assembly, the refractory bricks being held in an adjacent position by a securing device, a hanger rod with a locking mechanism at one end and a hook at the other end, a hanger having opposed refractory engaging projections adapted to engage the hanger recesses, a hanger rod hole allowing free rotation about the hanger rod end above the locking mechanism, and a locking mechanism engagement recess which when engaged with the locking mechanism prevents rotation of the hanger rod in relation to the hanger at 90 degree increments and provides that depression of the one end of the hanger rod into the locking mechanism engagement recess permits rotation of the hanger rod with respect to the hanger. The locking mechanism comprises opposing tabs. The hanger forms at least one slot adapted to permit the opposing tabs of the locking mechanism to pass through the hanger. The hanger forms engagement recesses adapted to receive the opposing tabs, the engagement recesses being offset laterally with respect to the at least one slot.
