This is perfect for hanging your lights above the tank but, the anchor and bolt that are included are sub par and a pain to use. Instead and this won’t work for all but in my case and how they want you to hang it it works. Instead of using the included anchor system because it wouldn’t work I tried for 3 hours with multiple trips to home Depot to try using the included anchor and a longer screw the included one is about 2-1/4” which was not long enough to go threw roof 2x4 and have room for the anchor to open. Instead of drilling a 5/8 hole in your roof for that silly anchor, take a wood screw and drill that straight into the stud. Boom that took 3 min all you had to do was find a nice fitting wood screw. I used a 3” star bit wood screw. If you wanna use their anchor and bolt go for it but when it doesn’t work cuz the included screw is too long. Slap some silicon over that 5/8 hole above your tank a throw a wood screw in there. There system will only work for just dry wall or your roofing it can’t fit threw a stud they did it on to how to vid online but only threw a 2x4 no roof material too...... just have a wood screw on hand if you plane on putting this to a stud
