I have two acrylic mounts for sea swirls, I have a glass tank so no need for them. They work for 3/4 or 1 icnh sea swirls. They are in good condition, work perfect. They are $25 new each, so lets do $30 for both + shipping. I'm in CA (94952)

"This bracket allows you to mount the 1" Swirl to tanks with "glass perimeter bracing" such as Oceanic and custom made tanks. Also allows you to mount your unit to acrylic tanks at the rear of the access holes in the top panel without drilling a hole to allow the outlet to enter the tank. Obviously, the outlet of the Swirl will be further away from the rear panel mounting this way and be careful to keep your Swirl 12" away from MH lights."
PM me I accept paypay.
