“FS” flexible braid jumper straps are recommended to compensate for motion due to expansion, contraction, vibration and operational movement of current carrying members. Manufactured from flat, extra-flexible tinned braid, they are available in a wide variety of sizes and amperages. The ferrules are made from pure electrolytic copper and are tin-plated. Standard mounting holes are 9/16” NEMA spaded holes. Other sizes and styles are available. We can also provide the flexible strap, without the end ferrules, on a price per inch basis. Please contact NSi for price and availability information.
