Extra Long Double-Ended Clamp (Single)

10 reviews
SKU: ACH041.1

An extended version of the Double-Ended Clamp, this clamp reaches places that no Double-Ended Clamp has ever reached before, while sharing all of the same qualities that we know and love. This clamp measures 5" from the center of one clamped tube to the center of the other clamped tube.

The same-sided bolt setup means that installation is a breeze, because you don't have to remove other things from your tube. The high surface area of the Extra Long Double-Ended Clamp's grip securely clamps into place, holding any accessories or mounts wherever you want them to be.


1. What an odd shaped clamp. How does it work?

This clamp is designed to be a low clearance, medium duty clamp that's easy to install. The sides just pop apart and you put the clamp where you want. Usually, all you have to do is temporarily remove the bolts to wrap the clamp around a tube.

2. What can I hold with it?

Any round, straight tube that is the right diameter. We an ever-growing library of clamp sizes. It's important the tube is straight for the 1/2 inch (12.7mm) where the clamp is attached. The tube can curve around in other places, but where the clamp is attached needs to be straight.

3. How strong it it?

Pretty strong, we call it medium strength. It's designed for versatility and ease of installation more than maximum strength. It's designed to hold  accessories (under 5 lbs, 2kg or so). It definitely not designed for attaching critical things like steering components, heavy accessories, or exit assist handles. What it can handle strongly depends on the amount of leverage you put on it of course, so the overall design matters a lot. It is possible to boost the strength considerably by using a pair of clamps spaced apart from one another, we do that on some of the SeatSide Mounts.

4. Can I use it on things that aren't the "proper" size?

Unfortunately, no. For the clamp to grip well, it needs to be gripping something that is round, straight, and the rated size. Fortunately, that is usually possible.

Clamps for a rectangular frame

I wanted to mount a side bag on my Catrike. I have the TerraCycle side mount bar, but two bags that I tried would not stay in place on the bar. The clamps swiveled around the bar and drooped down so I couldn't access the bag. Decided to make my own bag, so I started by creating a rectangular frame with two of these clamps holding another 7/8" piece of tubing parallel to the side mount bar. It holds steady as a rock. As the photo shows, my bag wraps around the clamps on the ends and the tubing on the sides so I have a bag held open and easy to access while riding. Now I'm seeing new possibilities for TerraCycle parts in other mounting situations.
