FUJI Top Cover QTC-20

Mounting part rod diameter: 20mm or less.
Material: Clear smoke polycarbonate.
Belt fixing structure securely holds even small diameter rods. The V-shaped fixing part and strong belt securely fix the rod, especially effective with small diameter rods. The belt comes out from the bottom, so even if it gets curly, it's easy to see and doesn't get in the way when you put it on and take it off. (Same structure as IDTC)
