Profile: National Rubber Co. is a designer & developer of the razorback plate series. We supply products from rubber to lift truck attachments for the material handling industry. A special NR Duro-Rubber Formula and mold design allows for minimum clamping pressure, without slippage, and rubber that will last. NR can meet all the needs of OEM replacement, and refacing. We offer a full line of replacements for your carton clamps. We offer the same tough rubber that is applied to clamps, for your paper rolls. With the mold design and cushion effect, this greatly reduces damage.
