Tired of speedrail clamps that give you sloppy connections? Me too. Proud to introduce the best free spinning “cheeseborough” type speedrail clamp made. The super tough and solid CineMilled “Houdini-360” clamps!

Once we began testing our new Action Arm, I had to start building the rigging kit on both my SUV and pickup truck and quickly began to get frustrated with existing speedrail “cheeseborough” type clamps because of the “play” that all the clamps I was using had.

So we developed the ultimate 360° adjustable “handcuff” or “cheeseborough” speedrail clamp. So strong even Houdini couldn’t get out of them!

Simply slide your speedrail tubes into place, line your clamps up and tighten the main bolt and your set!

3/8-16 threaded holes for additional rigging on the sides and top, you can even use the top thread with a set screw to provide additional speedrail locking!
