Need to clean up the look of your aluminum frame and keep out dust? This PVC slot cover seal is perfect for that. You get a long 20-meter (about 65.6 feet) roll of soft, silver-colored PVC strip that's exactly 6mm wide. It's designed to snap right into the groove on standard 2020 series aluminum extrusions – the kind used for building 3D printers, CNC machines, workbenches, and robot frames. It flattens out the slot, makes everything look neater, and helps protect against dust and debris getting inside. Super easy to use: just cut a piece to the length you need and press it into the groove. The PVC is flexible and durable. Just keep in mind measurements are manual, so there might be a tiny tolerance of around +/- 0.1 inch. A simple, effective upgrade for any DIY or workshop project.
