    A good quality kit is pretty expensive.&nbsp; If you are not planning on
    cutting 100's of holes I would look at places like harbor freight<br>

    Look for a conversion chart because the actual hole sizes are much
    larger than the conduit size marked on them.&nbsp; 1 1/4" conduit size is
    a 1.7" hole<br>
