What the thread found

• Iris rod attachments are available from multiple suppliers including Baer-Bel and Pro
• Hole spacing between different baseplate manufacturers can differ, potentially due to metric versus imperial measurement systems
• Iris rods from one manufacturer may not align properly with baseplates from a different manufacturer
• Purchasing the iris rod from the same manufacturer as the baseplate reduces compatibility issues
• If the rod does not fit the existing baseplate, tapping new holes into the baseplate is a viable solution that takes approximately ten minutes

Depends on

• The discussion references specific product links that may no longer be active
• No definitive confirmation was provided about which specific rod model matches the user's baseplate
• The metric versus imperial measurement discrepancy is stated as a possibility but not definitively confirmed
