|How It Works
Often used in combination with the Invisiware® receiver, this fitting is also hidden inside the end post with only the head exposed on the outside of the post. When installed, it looks the same as the Invisiware® receiver except it costs much less.
Invisiware® radius ferrules are used with pipe and with round, square or rectangular metal tubing. Pipe ends are counterbored, so the full perimeter of the head rests on a flat surface in the pipe. The head rests on the outside wall of a flat-sided metal post. A plastic washer is included and acts as a scratch-resistant barrier between the head of the fitting and the metal post.
For use in wood, the Invisiware® radius ferrule can rest against the outside of the post or the post can be counterbored with the radius ferrule recessed in the post. For wood applications, also order a Stainless Steel Washer, Part No. 11HW14.
