A modular protection and security device for protecting a boat within a slip having: a stationary bowed frame positioned over the boat slip; a plurality of stationary frame tracks mounted to a side of the stationary bowed frame; a plurality of upper track rollers mounted to the stationary bowed frame; a moveable bowed frame mounted to the upper track rollers and slidable over the stationary bowed frame; a plurality of moveable frame tracks, each moveable frame track mounted to a side of the moveable bowed frame; a plurality of lower track rollers mounted to the movable bowed frame positioned for rolling within in the stationary frame tracks; a first flexible sheath mounted to the stationary bowed frame and a second flexible sheath mounted to the moveable bowed frame, wherein the first flexible sheath is configured to fit between the moveable bowed frame and the stationary bowed frame.

A tonneau cover securing apparatus for removably securing a cover to a support frame attached to a pickup truck. The support frame preferably includes two opposing side rails that can be secured to respective sidewalls of the pickup truck, such that the cover can be secured to the side rails and the pickup truck by the securing apparatus, which preferably includes a channel, a locking member and a draw cord secured to the locking member. The locking member is biased toward a first position in which the securing apparatus can be prevented from disengaging from the respective side rail; wherein the draw cord can draw the locking member from the first position to a second position, in which the securing apparatus can be disengaged from the respective side rail. The securing apparatus preferably includes two locking members. Methods of securing a cover to a pickup truck are also disclosed.

A waterproof cover for outdoor products comprising having a tarpaulin, a plurality of binding straps, a tensioning assembly, and a support column assembly is disclosed. The tarpaulin comprises a ceiling part composed of flexible materials. The plurality of binding straps are used for fixing to outdoor products. The edge of the tensioning assembly is fastened to the edge of the inner surface of the ceiling part. The top end of the support column assembly is fastened to the inner surface of the center of the ceiling part, the bottom end of the support column assembly is fixed at the center of the tensioning assembly. Through fixing the flexible binding belts to an outdoor product, the flexible tension assembly is tensioned, and the roof of the tarpaulin is jacked up to form a slope, thus avoiding water accumulation in the roof of the waterproof cover.
