T-Shaped grommets are commonly used to organise and protect wires and cables. They help prevent abrasion and damage to cables, ensuring a neat and secure arrangement. When the plugs are inserted they may require a tighter fit or additional methods such as adhesives or fasteners for achieving a proper seal. They are generally used for sealing holes in applications where a permanent or semi-permanent seal is required such as in electronic devices, computer systems, automotive applications, and various other setups where cable management is crucial. Other uses include DIY projects, home improvement, and industrial applications. Additionally, they are resistant to temperature extremes and environmental factors, making them suitable for both indoor and outdoor use.
