DeWalt PFM2521350 3/8"-1/2" Multi-Thread WOOD-KNOCKER II Wood Form Insert

The DeWalt PFM2521350 WOOD-KNOCKER II Multi-Thread Wood Form Insert provides a secure, reusable anchor point for threaded rod connections in wood formwork. Built for demanding concrete jobsites, this insert delivers strong holding power, fast installation, and consistent performance when attaching hangers, supports, or temporary fixtures before and during pours.

What it does: Creates a robust threaded connection in wood forms so you can quickly install 3/8"–1/2" threaded rod for pipe supports, cable trays, lighting, bracing, and general form accessories. The multi-thread profile maximizes bite and pull-out resistance in typical construction lumber.
