Cobra Class 4 Sewing Machine

When your work demands maximum power and extra working room, the Cobra Class 4 delivers. Featuring a generous 16-1/2" cylinder arm, this heavy-duty stitcher provides the additional throat space needed for larger projects while offering the power and precision required for the thickest leather applications. From custom saddles and tack to heavy belts, holsters, and saddle bags, the Class 4 has earned its reputation as one of the most versatile heavy stitchers available.

Built with a triple feed mechanism, the Cobra Class 4 handles multiple layers of leather with ease, sewing materials from 3/32" up to 7/8" thick, including several layers of saddle skirting. It accommodates thread sizes from #138 through #415, making it an excellent choice for projects that demand bold, durable stitching and professional-quality results.

The extended 16-1/2" cylinder arm offers a significant advantage when working on large or awkward projects, giving you the clearance needed to maneuver oversized leather goods with ease. Whether you're building saddle bags, repairing tack, crafting holsters, sewing knife sheaths, or producing heavy-duty belts, the additional workspace helps make even challenging projects more manageable.

Beyond leather, the Cobra Class 4 is equally capable of sewing saddle pads, blankets, webbing, canvas, and certain plastics such as Kydex, making it a valuable addition to professional shops that work with a variety of heavy materials.

Every Cobra Class 4 comes mounted on a heavy-duty pedestal stand with locking casters and includes a powerful servo motor with heavy-duty speed reducer for exceptional control and punching power. For makers who prefer automatic needle positioning, an EPS Package is also available, replacing the standard Digital Servo Motor with a Needle Position Motor.

Whether you're equipping a professional production shop or investing in a machine that will handle virtually every heavy leather project imaginable, the Cobra Class 4 offers the durability, versatility, and performance serious leatherworkers rely on every day.
