C clamp

As the title suggests, I'm curious about using C lamps to tie my ski up to a dock that does not have cleats. My idea is to clamp the edge of the dock boards at the bow and stern far enough apart that the Ski is secure between both.This particular dock is best suited for boats that are high enough to rest against the dock edges using their own bumpers and tying around the pylons. This would only be used to dock for an hour or so while we eat and have a drink before getting back on the water. Has anyone come up with a better solution to a docking situation like this? Worth noting, the pylons are about 12 feet in between using the VX HO as a measuring device.

I am using Oculus Rift S and as much as I like the game, I am getting tired (mentally and physically) of having to grab everything in a c clamp grip for the sights to not jump all over the place.

Is there a way to set it up so that the gun stays stationary when I grab it?

Thanks in advance...

I don't know if what I'm looking for is actually a thing, but what I have in a mind is a c-clamp where the part opposite the threads is a pin rather than a flat plate. The idea is that the pin goes into a hole drilled into the top wall of some square steel tube with the end of the pin either clamping against the inside of the bottom wall of the tube, or via friction with the sides of the drilled hole.

Sort of this like this pocket hole vise-grip clamp that Kreg makes, but as a threaded c-clamp rather than a vise-grip.

Anyone know of something like I'm describing?

So as to not cause an x-y problem, here's what I'm trying to do:
I'm making a pair of load bars that will go on the top of my truck bed's walls. Each one is a 6' length of 2" steel tube with a 12" length of the same tube acting as a "foot" on either end. I'm trying to figure out how to clamp those "feet" to the bed walls.

Does anyone know of any companies that make C and L clamps in Canada? All I could find were Canadian distributors.

(Mods if this doesn't go here please point me in the right way? :))

Like the title says, I'm looking for a clamp to hold my mic boom arm or a new set up that allows a thickness larger than 2.5". My current desk doesn't have a lip wide enough to hold the full clamp securely, and the desk and frame is a bit too wide to fit my current clamp. I've already tried two different clamps that were supposed to be different gaps, but they were the same in the end. If anyone knows of one or currently uses one, suggestions would be greatly appreciated.

Thank you!

One of the C-Clamps that mount my DFGT broke.

Anyone got a US source for these that isnt overpriced? I'm also considering having one 3D printed but I don't know how durable they would be.

I am talking about the alex desk with 2 drawers and that is about 6" thick , I regret buying it, at first it was nice to have the drawer to do cable management on the back but now I have a dual monitor setup and cable management and desk space is really hard , I am using a 2 monitor stand but its an issue as it takes some desk space, and everytime I want to move my desktop around or add something I have to move everything to access the drawer.

I am about to juts move my desktop from tpo of the desk to under the desk if I ever find a small table that can hold my desktop on the floor without issue or just get a smaller table ( limited space ) with no drawers and ues that one for my computer and leave the alex as asecondary table for other stuff .
