Abstract: A receiver extends from the top of a retractable wheel assembly to receive the lower end of a jackstand or the like. Upon exerting pressure on a foot operated plate, a wheel is extended from the bottom of a plate and locked in place with a catch to permit transport of a trailer or the like attached to the jackstand. Upon release of the catch, the wheel will retract to bring the plate into contact with the ground and immobilize the trailer.

Abstract: A deck mounted fitting provides for extraction and retraction of a mooring line for a vessel. A container below deck may be used to store the mooring line. Extraction of the mooring line may be manually carried out and retraction of the mooring line may be carried out manually or by a selectively actuatable electric motor or wound spring rotating a wheel in engagement with the mooring line. A collar is disposed within the fitting to maintain the mooring line available for manual extraction during mooring of the vessel.
