Got a messy hole or a sharp edge where cables pass through? These Silicone Rubber Grommets and Plugs are your best friend for clean DIY and electronics projects. This is an assorted set featuring different sizes, with inner diameters ranging from about 18mm up to 50.6mm. They're made from flexible silicone rubber, which makes them easy to snap into place in drilled holes (in plastic, metal, wood, etc.) without needing tools. Once installed, they protect wires and cables from being cut or worn by sharp edges, and they also help keep out dust, moisture, and debris. You can also use the solid plugs to seal up unused holes completely. They're unbranded but are brand new and super handy for organizing computer wiring, customizing car interiors, building speaker boxes, or tidying up workshop equipment. Having a variety of sizes means you'll likely have the right one for the job. It's a small investment that makes a huge difference in making your projects look professional and protecting your gear.
