My exclusive design, printed in reef-safe PETG. These provide a very sturdy and attractive way to raise your egg crate off the bottom of your tank. This model will lift your egg crate 17mm (~.67) inches. They work well for show tanks and setups where you don't want anything like a heater under the rack. The leg pops upwards through the egg crate, and then a cap slides in from above to keep the legs in place as you move them. Price is for a set of 4.
