The 4-Sided Columns are the workhorses of the Jergens Production Vise Columns. They have eight statons for holding your parts. Two standard bases are available. The universal base will mount directly to most HMC tables, using the provided mounting holes on 80MM or 100MM centers. Increase your productivity even more by adding the Jergens Ball Lock Mounting System to your HMC. Exchange your vise columns and any other fixture in less than a minute. Location of all fixtures will repeat within .0005" every time. Custom mounting patterns and base dimensions are available. Please contact Jergens Customer Service for more information.
