Aquarium safe silicone 2.7 oz tube.
One tube should be enough for two 10 gallon kits, or one 20 gallon kit. 40 gallon kit may require two tubes.
Just like the picture. Works perfectly for me. One hinge is a little crooked so it squeaks when I open it but still works.
Perfect size to attach your door to your tank. No issues. Easy to manage and clean!
Easy to install, good quality for the price. Did NOT fit in my off brand tank, I did need to get an aqueon brand but no big deal there.
Was easy to install and works for what I needed it for. Thanks!
