The Razorback® Spiked Fence Rail is a simple, cost-effective way to transform any Promax™ system into a high-security spiked fence.
Unlike bolt-on toppings, Razorback® rails are manufactured with integrated spikes – no extra components, no extra installation time, and no compromise on strength.
Precision-formed 25 mm triangular spikes run continuously along the rail, creating a visually intimidating and physically effective anti-climb barrier. By preventing the top rail being used as a handhold or leverage point, Razorback® rails deliver superior spiked fence protection without altering your standard installation process.
Manufactured from high-strength 350-grade steel and hot-dip galvanised to AS/NZS 4680:2006, Razorback® rails are engineered for durability in harsh environments. They integrate seamlessly with Promax™ 358 mesh, attaching directly to the post with M8 cup head bolts and Promax™ fixing clips for a clean, secure finish.
