Hayden Nilos Strap Tensioner.
Hayden Nilos Strap Tensioner. Made from Steel with Bakelite handles. Size 9′ x 1 1/2″ inches.
These Tensioners were used along with the Hayden Nilos Straps, a strip of alloy metal in various widths and lengths, though normally 1/2″ inch with a buckle type attachment at one end. The strap would go around the end of a water bag/hose inserted onto a water pump and tensioned using this tool to prevent it from coming off, similar to a Jubilee Clip. The excess was also cut off using the same tool.
