25-INCH LONG ARM • DOUBLE NEEDLE • COMPOUND FEED
The CONSEW 339RBL-25 is a heavy-duty industrial double-needle lockstitch sewing machine designed for professional sewing operations involving large panels, layered materials, and parallel seam construction.
Its extended 25-inch long-arm workspace provides additional clearance for handling oversized sewing projects such as upholstery panels, canvas products, industrial covers, and other substantial textile assemblies.
The compound-feed walking-foot mechanism combines needle feed, drop feed, and alternating presser feet to help maintain controlled material movement when sewing leather, vinyl, canvas, synthetic fabrics, and other medium-to-heavy materials.
