Abstract: A torque limiter and a retrievable chain knocker tool, each separately configured for use with a drain cleaning apparatus are described. The drain cleaning apparatus includes a drum housing defining an interior region, a cable carrier rotatably mounted within the housing interior region, and a transmission assembly operatively configured for transferring rotary power to an end portion of flexible cable retained in the housing.

Abstract: An insect moat for bee hive stand legs has a base and a lid. An outer moat wall encloses an inner moat wall on a bottom plate, forming a moat between the inner and outer moat walls within which an insect impeding substance can be places. The inner moat wall encloses a leg chamber. A lid is removably engaged atop the base, and occludes any vertical passage into the moat, preventing rainwater, debris or stray bees from getting into the moat. A leg of a bee hive stand or other outdoor furniture is placed within a leg chamber of the base defined as within the inner moat wall, traversing through an opening in the lid, thereby being protected from the advance of ants or other crawling insects up the stand leg. A plurality of holes traversing through the bottom plate allows any rainwater to drain from the leg chamber.
