Designed Fenderhook for the more generic mooring needs where custom design and fabrication are not needed. The core structure is durable aluminum. Outer and inner surfaces are covered with premium-grade maintenance-free leather in your choice of black or brown finish for an outstanding look. The finest soft sheepskin covers the inside of FH models to protect the rail surface area of varnished or painted rails. For use with lines up to 5/8" "Seabob not included".
