An apparatus including a collapsible body, a base, and a cap. The body including a spring element coupled to the body to apply an extension force. The spring element having a helical geometry. The collapsible body has a high visibility characteristic. The base is coupled to a first end of the body and has a shape to secure the body and the spring element relative to the base and to receive the body in a collapsed state. The base includes a base coupling element to secure the body in the collapsed state. The cap is coupled to a second end of the body opposite the first end, the cap to, at least partially, close the second end of the body.

A weighted unit is provided. The weighted unit includes an enclosed shape, the shape having horizontal channels running along the entire base of the unit from one side to an opposing side, such that the horizontal channel is open to each opposing side, the weighted unit being placed over a horizontal and/or vertical member of an object to be held down with the channel engaging the horizontal member to hold the object in place. Protrusions or other features are integrally formed in the weighted unit to allow the weighted unit to hang from the object to be weighed down without the weighted unit touching the ground. The weighted unit may be placed directly over the top of a horizontal member of the object to be weighed down without also engaging, or being placed around, a vertical component of the same object.
