发明名称 Ladder attachment
摘要 A ladder attachment including an elongated one piece member preferably molded from an elastomeric material and formed with an arcuate cavity on one side sized to approximately correspond to the outside of a utility pole or tree trunk and having a pair of end parts each formed with a hole sized to receive the upper end of a ladder stile to be mountable crosswise to the upper end of the ladder. A pair of curved slits are formed into the one side of the member each extending around one side of the cavity to form a pair of concentric curved gripper wing portions concentric to the cavity which are drawn together with a strap, which has ends connected together with a cinch to secure the ends together.
