OVERVIEW: Spiral bolt clamps are used on hoses with a convoluted cover. The clamps are made of plated steel, and are the clockwise version for use on Hosecraft USA hoses.
To determine which style clamp you need, look at the end of the hose. If the helix spirals in a clockwise direction away from you (along the hose), a clockwise clamp is needed. The hose outer diameter (OD) should be between DIA1 and DIA2 shown in the table below.
