Abstract
Abstract A loop for leveling a hanging lamp. The loop has several notches for holding the lowermost link of a swag chain at several possible positions along the interior of the loop. The loop is then affixed to a lamp in a manner which permits turning it to any desired location so that a hanging lamp which would not hang straight if hung from its center may be made to hang straight by placing the lowermost link in a notch other than the center notch and rotating the loop to a position to correct the imbalance.
