The unique construction of Standard Reusable Nylon Tree Clips permits ratcheting up or down under conditions where other fin or tree-type fasteners would become distorted and unusable, particularly when removed in the field. These X-mas tree clips, also called nylon barbed rivets, feature a ribbed shaft and self-centering construction to assure easy insertion and removal without damage or distortion to retaining fins. As the ratchet style clip is pushed into place, its ribs deflect then spring back after passing through the hole. It fastens securely in prepared or blind holes in a wide range of materials.
