Abstract: Devices, systems, and methods for portable, free-standing exhaust systems for exhausting gases from internal combustion type engines, including portable generators. Portable, free-standing exhaust system comprising a plurality of metal exhaust stack sections, forming a continuous hollow column; a housing stand with legs holding the column; a hanger bracket connecting the housing stand and a connector tube, including a separation space, which is connected to an exhaust pipe for exhausting gases.

Abstract: A ground anchor having an elongated shaft with upper and lower ends, a grooved locking post on the upper end; an threaded auger fixed to the lower end, an engagement area for engaging an external tool, a sleeve mounted over the main shaft, which spins freely, and an attachment member configured to secure one or more of an external lock, chain, rope or cable attached to an external object to thereby anchor the external object when the main shaft is screwed into the ground, and a lock device configured to cover and lock onto the grooved locking post so the attachment member and sleeve cannot be removed, whereby the sleeve covers the main shaft and obstructs access to the main shaft to prevent unwanted persons from removing it.
