Could anyone point me to a pool light j-box that has the capability to accept (2) niche light cords. I have a 3 hole j- box now but it only provides 1 of the 3 entries with a strain relief for the cord.Are these boxes designed to only accept 1 cord so you have to purchase another box for the light at the other end of the pool? The product I have now is a Hayward SP681A. Thanks for any help offered.
