A device, system, and method for holding one or more structural long objects includes a plurality of adjacent flat membranes that are in direct contact with each other. The membranes have been slit to produce tabs that meet near a center of the membranes to hold the structural long object(s) more effectively than could be accomplished with a single flat membrane with tabs. The membranes are held in the body of the device or system by a retaining device located on one side of the membranes and a retaining feature of the body on the other side of the membranes.
