An essential building block for anyone looking to tinker toy their way to recumbent success is the Double-Ended Clamp! The open-ended two-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 Double-Ended Clamp's grip securely clamps into place, holding light 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. That's why the ends are open- it gives you more room to get up close to things, and it makes it easier to install the clamp. The sides just pop apart and you put the clamp where you want. Usually, all you have to do is remove one bolt and loosen the other 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 light duty because the four-bolt Double-Ended Clamps are meant for most applications. It's designed for versatility and ease of installation more than maximum strength. It's designed to hold light accessories (under 2 lbs, 1kg 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.
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.
- Machined from 6061 aluminum, anodized black. Available in multiple sizes, be sure to use clamps sized exactly for the tubing you wish to clamp.
- 7/8" (22.2mm) to 7/8" (22.2mm) clamp weighs 41 grams. 1" (25.4mm) to 7/8" (22.2mm) clamp weighs 43 grams. Anodized black coating, stainless steel hardware.
- There are three basic ways to install a clamp, depending on the tube it is going on. The first is to loosen the bolts and slide the clamp over the tube(s). If there are obstacles on one of the tubes, you'll need to remove one bolt, loosen the other, swivel the clamp open, and put it over the tube. If both tubes have obstacles, simply remove both bolts, put the halves of the clamp around the tubes, and reinstall the bolts.
- Fits nearly any place you would like to clamp two tubes so they are parallel to each other.
More great stuff.
I have used several of these clamps, I trust you guys to make first rate gear.
2 of these clamps were exactly what I needed to attach the 7-inch, 7/8-inch diameter tube to my 1-inch diameter side bag tube.
I use this clamp in conjunction with my TerraCycle Multi-Purpose Accessory Mount, which isn't quite wide enough to hold my GoPro camera and headlight at the same time. I attached one end of the clamp to the mount, and the other to a 4" x 7/8" TerraCycle tube. This gives provides enough space to fit both of my accessories. Like all TerraCycle products, the clamp is solid, well-made, and very versatile.
It's a bit expensive, that being said it is also a required item needed to attached your accessories to your recumbent trike. Good workmanship and solid.
