Abstract: The present disclosure envisages an anchor plate adapter. The anchor plate adapter comprises two or more type of locking interfaces to facilitate mounting of different chimneys. One or more first locking interfaces is configured on the adapter, wherein the first locking interface is configured as opposing holes on an inner wall and an outer wall. The chimney is securely mounted on and locked by means of one or more fasteners. Additionally, one or more second locking interfaces are configured in form of protrusions extending outward from the outer wall. The second locking interface engages with the inner protruding member configured on an abutting surface of the outer tube when the adapter is oriented in a position within a female interface of the chimney, and the female interface is rotated with respect to the adapter.

Abstract: A roof curb is used in association with a roof flashing installed on a roof with an incline and corrugated ribs, the roof flashing having a base member that may be mounted over a substantially vertical chimney in the roof and a hollow member having a first end and a second end, the first end being larger than the second end and the first end being attached to the base member of the roof flashing. The roof curb includes a first skid and a second skid that may be mounted upon the roof substantially in a direction of the incline and substantially parallel to each other.

Abstract: A device comprising an adjustable band configured to be installed around a pipe and a locking assembly disposed on the adjustable band.

Abstract: A duct cleaning apparatus for cleaning an inside surface of a duct including an elongated flexible element extending inside the duct having a first end supported in the duct spaced from an inside surface, a second opposed free end and having a length sufficient to engage the inside surface of the duct, preferably greater than the diameter of the duct. Fluid flow through the duct, particularly turbulent flow, causes the elongated flexible element to oscillate or flap, striking the inside surface and removing foreign material from a predetermined portion of the inside surface of the duct. The apparatus of this invention may be used to create a fire break, for example, by removing flammable particles or dust from an area of the duct, preventing a flame from propagating along the duct through the flammable material.
