BHP Tackle Bench Wind-On Jig

From BHP: 

"The BHP Bench Wind-On Jig is a heavy-duty bench mount jig designed for a lifetime of use. Made for use with the Beiter Winder, the leader connection is held super-tight with no slip or abrasion, providing ample vertical and horizontal working space. Works equally well for half-hitched servings. Machined from polished aluminum and stainless steel. Horizontal working room is 24"."
