摘要

The length adjuster for conduits to lamps, apparatus, electrical information technology equipment and machines is used in conjunction with fixed pulleys in ceilings, outlet boxes on walls, tables, apparatus, equipment and lamps. The adjuster is normally a pulley which can be rotated by hand or with the aid of a tool. The pulley is fixed with screws after the conduit length has been adjusted. - The pulley can be provided with a housing, which fits over it and through which the conduit can pass. The housing has grooves in each side, which coincide with grooves in the pulley.
