The Invisiware® Radius Ferrule is a concealed, swaged,
non-tensioning, through-the-post-mounted fitting that is
suitable for pitched or level runs. This fitting is available for
1/8”, 3/16”, 1/4”, 5/16”, and 3/8” diameter 1×19 stainless steel cable.


The Invisiware® Radius Ferrule must be used with a tensioning fitting on the opposite end of the run. It is the least expensive through-the-post fitting that we offer. This fitting has a head shaped to appear like the Invisiware® Receiver from the outside of the post (like the Invisiware® Receiver, the Invisiware® Radius Ferrule is concealed within the post). For these two reasons it is recommended to use the Invisiware® Radius Ferrule on one end of your cable run and an Invisiware® Receiver and Stud on the opposite end whenever practical to do so. The only reason not to consider this fitting as your non-tensioning end would be if you preferred to use a non-swaged solution.


This fitting installs into a hole drilled through the face of the post (to accommodate the cable at minimum) and a hole through the back side of the post to accommodate the fitting (see our Hardware Mounting / Hole Boring Guide). It also requires that you have at least 2” of clearance on the back side of your end post (the cable would likely be attached to the Radius Ferrule prior to installing it through the back side of the post). This fitting is furnished with a Delrin® washer that is installed between the shoulder of the fitting and the end post to protect the surface of the finish of the end post as tension is applied.


Using this fitting on pitched applications for 1/8” and 3/16” cable sizes simply requires kinking the cable where it exits the face of the post after initial tensioning. A kink is achieved by placing a piece of wood onto the cable where it exits the face of the post and striking it lightly with a hammer to create the kink.
