Abstract
A gripping sleeve slides onto a ratchet extension arm shaft. A proximal and a distal collar affixed to the ratchet extension arm prevent sliding or wobbling of the sleeve. The sleeve is gripped by a user to allow the user to steady and guide the tool head attached to the extension arm, which rotates freely within the sleeve. The user grips the sleeve with a bare or a gloved hand without damage to the hand or glove.
