Abstract: A system for securing accessories in a truck box comprises right and left anchor beams adapted to be fastened to respective right and left edges of the floor such that inner faces of the anchor beams face each other across an inner floor area. An anchor lip extends from each inner face and an accessory has right and left edges comprising an under lip adapted to fit slidingly under the anchor lip of each anchor member. A lock is operative to lock the accessory in a substantially fixed position along the length of the floor. The accessory can be ballast, a toolbox or other accessory that is secured in a truck box but is easily removed to load cargo.

Abstract: A multipurpose aquatic float has a molded shell of plastic resin. The float has a generally rectangular base part with a set of integral mounting flanges on its top surface. The mounting flanges are arranged to provide a longitudinal center channel for accepting a framing member of standard dimension lumber. Transverse flanges support the longitudinal flanges and provide a cross channel at the center and end notches to accommodate cross bracing in the frame on which the float is mounted. The longitudinal flanges have molded-in fastener receivers for receiving fasteners that secure the float in place on the framework of the support structure.
