at most one securing apparatus is required in one embodiment the securing arm of one securing apparatus may hold down one side of an object while the other side of the object may be held down by other means for example a stationary non rotatable securing arm permanently at the 45 u00b0 angle may be attached to the crossbar on the other side of the object the use of fewer securing apparatuses may be desirable for cost purposes as mentioned earlier the settable rotational mechanism and thus the attached securing arm can be set and held in various rotational positions such as the closed or open position there are many means for setting and holding the settable rotational mechanism one means of setting and holding the rotational position of the settable rotational mechanism is through a clamping mechanism that may be tightened to prevent further rotation another means of setting and holding the rotational position of the securing arm is by latching at various rotational angles for example one means of latching is by having a pin hole that holds a rotational position in place when a pin is in the hole the pin hole may be designed such that the rotational position is held and cannot be moved towards the open or secured position or may be designed such that the rotational position can be moved further towards the secured position but not the open position there may be multiple pin holes for the various rotational.
