The Krinner Comfort S is equipped with the original single cable operation. The clever clamping device guarantees equal claw pressure around the trunk. Just place your tree in the open stand and pump the foot pedal until the claws have firm contact to the trunk, ready! The tree stands absolutely firm and straight whether the trunk is thick, thin or crooked. The patented safety belt with its step by step ratchet mechanism provides additional safety so that the tree cannot fall over spontaneously.
