RWO's Powerbox Mast Controller is also known as its Mast Bend Magic Box. There is a lot of power packed into this little box, which can be secured to a deck-mounted base plate and used to push the mast and create bend. The extension arm mast pusher has a pad, so it will not scratch the mast. The box measures 7 1/2 in. (190mm) x 2 in. (51mm).
