Using the DeWalt PFM2521438 Wood - Knocker II+ is a breeze. First, make sure you have the right form for the concrete pour, like for floor slabs, roof slabs, or walls. Install the inserts onto the form. When it's time to attach steel threaded rods or bolts, the inserts can handle a range of sizes from 1/4 inch to 3/4 inch. Just pick the right size based on your project. The color - coding on the inserts will help you quickly identify the right one. When installing the rods or bolts, the hex impact plate will stop the insert from rotating in the concrete. As for the thickness, you can use these inserts in form pours that are at least 3.5 inches thick. Always check the installation details before starting. Maintenance is simple. Keep the inserts clean from dirt and debris. If they get wet, dry them thoroughly to prevent rust on the carbon steel parts. And remember, these inserts are designed to handle seismic and wind loading, so they're great for a variety of construction projects.
