This is a PSA sanding sheet designed for file sanding applications where you need a long, narrow abrasive that stays put during extended strokes. Model Number: \u003cstrong\u003e23-364-040\u003c\/strong\u003e.\u003c\/p\u003e\n      \u003cp\u003eThe main reason to buy this sheet is simple: it gives you coarse 40-grit cutting action in a file-sheet format that works well for leveling rough material quickly. If you're removing material instead of just refining a finish, 40 grit matters because it cuts fast and keeps the job moving. The aluminum oxide abrasive is a proven choice for general sanding work, especially when durability and consistent cut are more important than ultra-fine finish work.\u003c\/p\u003e\n      \u003cp\u003eMirka's Gold series is widely used because it balances cut rate, sheet life, and dependable performance without getting complicated. On a job that needs repeated sheet changes, the PSA backing helps. Instead of dealing with clamps or loose fit, you press the sheet in place and get full contact across the sanding surface. That matters for smoother tracking, more even pressure, and less wasted time when changing abrasives.\u003c\/p\u003e\n      \u003cp\u003eThe 2-3\/4 inch by 16-1\/2 inch size is what makes this product specific. It is not a general-purpose square sanding sheet. It is built for longer sanding files and similar tools that need a narrow, elongated abrasive. That shape is useful when you want to follow a straight line, smooth body filler, or work a long section without switching to a wider sheet that can feel clumsy in tighter or more detailed areas.\u003c\/p\u003e\n      \u003cp\u003eThis Mirka sanding sheet is sold in a 50-pack, which makes more sense for shop use than buying one-off abrasives. If you burn through coarse grit regularly, having a full box on hand keeps your workflow consistent. For bodywork, fabrication prep, or rough wood shaping, coarse sheets are usually the first step, so pack quantity matters more than people think.\u003c\/p\u003e\n      \u003cp\u003eWho should buy it? Anyone already using a compatible PSA sanding file and needing a coarse, long-format abrasive for serious prep work. It makes the most sense for auto body users, finishing shops, and serious DIYers who understand grit progression and want the right sheet size instead of forcing a standard sheet to do the job.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-whats-included\" class=\"acc\" open\u003e\n    \u003csummary\u003e\u003ch2\u003eWhat's in the
