What the thread found

• A wedge clamp designed by CP can lock down the dovetail connection on a Master sled top stage to increase rigidity during movement and vibration.
• The original clamp was used during professional film productions but is no longer manufactured by Tiffen.
• Aftermarket reproductions of the clamp can be machined from specifications, with anodizing recommended to reduce friction between sliding surfaces.
• The clamp design is reportedly compatible with both Master and Ultra 1 sled top stages if dovetail-to-stage clearance dimensions are similar.
• Users report that applying the clamp eliminates flexing in the top stage during dynamic camera movements.

Depends on

• The original clamp has limited documentation and is difficult to source.
• Compatibility between different sled models requires verification of physical clearances.
• Machining and anodizing costs affect affordability of reproduction units.
• No technical specifications or engineering drawings were provided in the discussion.
