This pin will fit a Hemingray 79 or Pyrex 3 piece stacker insulator. It measures 18 1/2" long. The pin is in good shape for a 100 year old piece of wood. I only have 3 of these pins left since they are hard to come by. $20.00 EACH plus shipping. Take 1, 2, or 3 as available. Payment by PayPal friends or gift mode or check.
