The Panel Clip has been designed to hook over the top of wood panels so that artworks may be hung using one of the Absolute cable, cord or rod methods without marking the surface of the panel. The clip is produced from stainless steel and lined with neoprene to avoid damage to the wood and to help maintain positioning of the clip.

The standard clip will fit 3/4'(19mm) wood panels.

You need to use top blocks to hold either the rods, cables or cords. The rod would require the H6051, top block for H track rod, and the cable and cord would require the H6052, top block for H track cord or cable. Seen here:
