The A series mount is absolutely fantastic The ability to hide the cables inside the mount make this a clean install

I should've bought these sooner. They're 10x better looking than the goosenecks, they're easier to adjust, cabling is 100x neater. Goosenecks are ok if on a budget, but for a little extra these are worth every penny.

Bought to fit my 160we tuna blue on my 30g nano, fit good and nice look, very overpriced I believe, very tight fit for the cords to fit through the tube, had to use a wire hanger and electrical tape to pull them through, poor instructions on that part, overall just bought it because I didn't want to hang from ceiling and this was only choice I had

Some modification and I used Kessil mount with Aqua Illumination Hydra 26 HD light. A lot sturdier than gooseneck mount and looks good too. Also used Aqua Illumination HMS bracket with mount and light. JBJ Rimless 30 tank.

Kessil has great customer service, I lost the C clamp adapter for the A160 Tunas and they are sending me another. This will help me mount these arms and Im liking the cord management here.

I'm very happy with these over the gooseneck arms I was using previously. I wanted to add some measurements that I wasn't able to find anyplace (and my question here never got answered). If you are using this on single lights, they work great on tanks much narrower than the description says. From the center of the vertical tube, each of the mounting holes in the closest position measure 8", 9.75" and 11.25" But the mounting bracket puts the vertical tube about 2" being the back glass of the tank, meaning you could center a single light over a 12" wide tank.

The picture of this product fooled me at first. Didn't realize it was for single lights AND panel lights.

I wanted to mount my AP 700's with these mounts but found that the mounting hardware would not properly fit my tank due to the plastic rim on my tank. What I ended up doing is making a mounting board that attaches to the wall behind the tank and then installing only the slide through holder to that. I was bummed at first but attaching the lights like that meant that I didn't have to have my tank three inches from the wall to accommodate the thump screws on the back. Now the thumb screws are on the tank side and easily accessible for adjustment if need be. I've also been thinking of just replacing them with allen set screws to clean up the look even more. Kessil could do way better in the design of these mounts for their high cost. The slide through bracket could be drilled and tapped for installation of the thrum screws/set screws on the back, and sides to allow more flexibility for installation. Buyers should also be warned that this mount may not necessarily fit their tanks. I just threw four machined brackets and plastic blocks in the trash.

Used to mount 2 a360we over my 120 gallon rimless, Looks gorgeous, easy to setup and allowed me to remove a canopy that I had been using to hold the lights. Have been using the lights with my canopy for a long time but could never quite put the lights where I wanted due to its construction. These let me put the lights right where I wanted them and my corals are responding very well.

These A Series mounts are FAR superior than the goosenecks! I believe they are worth the extra money!

I was looking for a way to hide the wires on my A360we and this item solved that issue flawlessly
