I'm selling a fresh out of the box, never been used, GPI PRO Telescoping Monitor Arm & Post Clamp Assembly. $900
I have had my Zephyr for 8 months now. Doing well, learning lots and having some fun and success. Recently got to fly an Alexa EV on a short and the week after it was an Alexa XT with Cooke 5/i. To date I have one one concern... My concern with the sled are the clamps. They are awefully stiff and hard to open and close. I am familiar with the "quick release" design from riding bikes for 20 years but these are definately not Shimano parts. The lower post clamp is managable but the gimble clamp is a bugger. When having the weight of the Alexa XT and a Cooke lens (23.7 lbs verified by a shipping scale) I opted to get it closed but then use an allen wrench to make it secure. --meaning when I could close the clamp it was not secure and the gimble could slide. After shortening the screw length and therefore the throw of the lever, I could not hand tighten it. I honestly thought the plastic parts would snap. After that shoot I took the sled to my shop and tried ot diagnose the issue. When applying force on the clamp lever it appears almost as if the screw inside was starting to bend or flex under the stress. I tried to find a replacement bolt in hopes of finding a sturdier one but the hardwre shop near by didn't have an exact match. I did toss a washer in help close the gap but this is a bandaid as best. Any suggestions what is going on here? Could I have a clamp assembly that needs attention or am I expecting too much out of the hardware for a secure fit on the post?
