This is one of my favourite methods of cooking.  With this addition to your Fire Pit 50, it will allow you to spit roast small to medium chickens and joints of meat over the open flame.  It has 4 lock in positions so you can cook evenly and manually.  It is a great way to pass time cooking on the open fire.  
 
The spike area is approx 30cm clearance.  Beautifully forged with lots of detail, it is a show off piece for your guests.
