The DEWALT PFM2521350 3/8' - 1/2' Wood-Knocker® II+ Cast-In-Place Concrete Inserts are a must - have for MEP and fire protection hangar attachments. These inserts are color - coded for easy size identification. They are installed on wooden forms for new concrete floor slabs, roof slabs, or walls. Once the forms are removed, the color - coded flange is clearly visible in the concrete surface. You can attach steel threaded rods or bolts with diameters from 1/4' to 3/4'. The hex impact plate stops rotation during installation. These inserts are fast and simple to install, with a low overall cost. They work in wood form pours just 3.5' thick. The insert design allows full thread engagement, and all sizes can handle tension and shear loading. Each box comes with 100 inserts. The product is made of carbon steel and engineered plastic, 2' in length, and has a max load capacity of 4820 Lb. It is code - listed as ICC - ES ESR - 3657.

Using the DEWALT Wood - Knocker II+ inserts is a breeze. First, identify the right size of the insert by its color - coding. Then, install it on the wooden forms that support newly poured concrete for floors, roofs, or walls. Make sure the wood form pour is at least 3.5' thick. When you install the steel threaded rod or bolt, the hex impact plate will prevent the insert from rotating. Just insert the rod or bolt and you're good to go. As for maintenance, keep the inserts dry to prevent rusting of the carbon steel parts. Check the inserts periodically for any signs of damage, especially if they've been under heavy load. If you notice any cracks or wear, replace them right away. And always follow the load capacity limit of 4820 Lb to ensure safety.
