Our original large binder we developed more than 25 years ago and has undergone constant refinement to make it the best available for quality marine canvas fabrication. It bolts on and off with a single screw without any other modifications to your machine and runs like a charm. Our large binder feeds directly onto the edge, automatically creating the facing on both sides, saving countless hours of fabrication time. Starting with a 4" strip and finishing to one and a half inches, our large binder is the mainstay of our fabrication method for finishing both the tops and sides of our enclosure panels as well as hiding all the zippers. We have sold countless large binders to both our students and to fabricators across the country and overseas, who use them on a daily basis. Many shops have a couple of our binders on site and use them daily to speed up quality fabrication of enclosures.  Our binders are hand made to our exacting specifications.
