The Pony Board Boss pulls boards into shape for professional results in deck installation. Used with the Pony #50-3/4" Pipe Clamp Fixture, the Board Boss pulls bowed and/or warped boards into position before fastening to deck joist. The Pony Board Boss can be used anywhere along the length of the previously installed board and is not limited to pushing off of joists as with other more expensive products on the market. The steel construction provides strength and the painted finish helps prevent rust. (Pony #50-3/4" Pipe Clamp Fixture sold seperately)
