The dimensions below are nominal in mm and applicable only to standard catalog offerings. Refer to Nexen product
drawings and CAD files for your product numbers for precise dimensions. Special and cut sections of rack may not conform
to these dimensions. The RPS 10 & 12 alignment tools do not require fasteners so no data is listed for them below.
Dimensions apply to standard length rack sections. Cut lengths and customs could vary. Refer to drawings for your specific product
numbers. * Bolt length will vary based on machine design.
