To use this mast clamp set, first select a pole with a diameter between 51 and 127mm. Then place the two pieces of the clamp around the pole where you want to mount the EASYPOE Box. Secure the clamp tightly to ensure a stable hold. When handling the clamps, be careful not to scratch the surface of the pole. For maintenance, regularly check the tightness of the clamp. If it starts to loosen, simply tighten the bolts. Keep the clamps dry and clean to prevent rusting and ensure long - term performance.
