The included frag plug lockers hold your frag plugs tightly and ensure no pesky fish or clean-up crew can knock your corals over and cause damage to them. While holding the plugs tight is their main focus, it also allows you to easily move the rack without having to worry about your frags falling on the way. Available in 4 unique color variations, with standard magnets that can hold up to 1/2in thick. 

All magnets are epoxy coated, and then fully encased in clear acrylic for your safety. You can easily inspect, remove, and upgrade your magnet strength at any point in the future.
