These are separable hinges commonly used on caskets for easy removal of the casket lid during finishing and upholstery after woodworking is completed. Use 4 per casket for a typical half couch (two piece lid) or full couch (one piece lid).  Sold in sets of 4. Also available in boxes of 100; enough hinges for 25 caskets.
