ABSTRACT:
A binder for carpet samples has a sturdy slotted anchor attached to the binder back with the anchor raised from the binder back in the region of the slot. A binder post has a head at one end for engagement within the slot by a swinging movement of the post relative to the anchor. A pair of lugs on the post and post head coact with the anchor slot to limit rotation of the post during installation. The end of the post away from the anchor is threaded and receives a nut placed above a top flap of the binder. Strength, durability, convenience and economy of manufacturing are featured.
