ABSTRACT:
The hot stick adaptor has two members that are adjustably movable relative to each other. A first one of the members has two separate first ratchet areas. A second one of the members has three separate second ratchet ares. A fastener and spring connect the two members to each other with one of the first ratchet areas and one of the second ratchet areas in interlocking engagement. The two members can be moved away from each other in a first direction, compressing the spring, to disengage the interlocking engagement and thereby allow the two members to be moved in a second direction.
