Polyurethane is an ideal material for arboring reel seats because it is lightweight and highly sensitive - increasing "feel" and transferring bites and strikes through the handle. The semi-porous polyurethane material absorbs epoxy glue quite well and ensures a strong bond with the rod blank and reel seat. Available to fit most common sizes of reel seats, these arbors all include a 1/4" pilot hole which can be easily reamed or drilled out to fit any rod blank.
