Resilient rods for use with hanging file holders

An adjustment member to be coupled to a rod for use in a filing system, the adjustment member comprising:

• a hook extending from an end of the adjustment member;
• a mounting portion including a means for mounting the adjustment member to the rod;
• a resilient structure coupled to the hook and the mounting portion, the resilient structure configured to permit the hook to dynamically move longitudinally along an axis of the rod and adjust an effective length of the adjustment member by adjusting the length of the resilient structure in response to a lateral displacement imposed on the rod by force applied at an angle to the axis, the resilient structure biased to draw the hook toward the mounting portion;
• a limiting portion extending from the adjustment member spaced a first distance from the resilient structure;
• and
• an extension portion extending from the adjustment member spaced a second distance from the resilient structure, the second distance greater than the first distance, the extension portion including a radiused portion disposed on an underside of the adjustment member, the radiused portion being convex.
