Zappa Rail Fencing Installation is simple and fast thanks to our Insul-Strainer tensioning system. The Insul-Strainer bolts onto the straining post permanently and the rail slides onto it. This lets the rail rotate around its insulated spool, so you tension and insulate the rail with the one device.

You can also slacken off and re-tension the Insul-Strainer anytime.

Specially designed brackets let you attach Zappa Rail to timber, steel, and our own Timberline Posts. The brackets also allow you to contour the rail to the natural undulations in your land.


Zappa Rail is attached to your post of choice using our special bracketing system, which allows the rail to contour gradients of up to 22.5 degrees!


Make sure you have a strong end assembly that you can fix your insul-strainer onto. The Insul-strainer is simple – just slide the Zappa rail into it and tension it up with a spanner. And because it’s permanently mounted to your end assembly you can easily re -tension the rail if it becomes slack.
