The Krinner Tree Genie Medium is equipped with the original single cable operation. The foot pedal has an integrated bell that ‘DINGS’ when the claws have securely closed around the trunk. At the same time the foot pedal is automatically secured in the locked position. Last but not least, the tree stand comes with the patented safety belt to provide extra security. Just place your tree in the stand and pump the foot pedal until the bell ‘dings’ and you are done. Max Tree Height - 7 Ft. Max Trunk Diameter - 4.7 Inches. 1.2 gallon water reservoir.
