To install a 131mm high interior drawer you will require a front attachment kit to secure the front panel to the Vertex drawer. Its installation is simple and is done by screwing them on each side of the panel. They will provide resistance and security to it, immobilizing it and adjusting it to its place. Made of white plastic, they will effectively withstand the passage of time, as it is a durable material, while easy to clean, so its appearance will always remain as it was new.
