The Universal Super Crab Gripper Clamp from CAMVATE is constructed from aluminum and steel materials with a nonslip rubber pad to prevent accidental falloff. This clamp provides a .4 to 1.2" range with a maximum open jaw of 2.1". It can be sturdily and conveniently secured on a tripod leg, water pipe, handrail, pole, shelf, table, branch, and more. Featuring a strengthened screw knob for a firmer gripping force, it allows you to comfortably lock or release it. In addition, its ratchet lever is designed for smooth rotation and effortless use. The clamp has three 1/4"-20 holes and one 3/8"-16 threaded hole to provide mounting points for optional accessories.

Related Questions and Answers

Q: 1. Can you use the Peak Design Quick release plate on this?

A: Yes, the Really Right Stuff B2-mAS Screw-Knob Clamp with 1/4"-20 Screw (38mm) should be compatible with the Peak Design PL-S-3 Standard Plate (BH #PEPLS3), because the plate uses the same Arca-Type quick-release design.

Q: 2. Sunwayfoto also makes this rail with a locking lever instead of a knob. I see B&H does not carry that version. I actually prefer the convenience of the lever, but is the knob actually more secure?

A: Both are very secure and a matter of personal preference. With the knob, you can apply more tightening force than the lever but of course the lever is more convenient.

Q: 3. Is it compatible with Sunwayfoto DP-26? Do you a photo with this two assembled?Is this a good choice to use a small snapshot (Nikon aw120)? or do you have a better one? (the plate and the base)Thanks

A: Yes, the Sunwayfoto DDC-26 Mini Screw-Knob Clamp is compatible with the Sunwayfoto DP-26. Unfortunately, we do not have an image with the two items assembled. These two products will be a great choice for a compact camera system such as the Nikon AW120.

Q: 4. Two questions, really:1. Bill in GA wrote: It's being used to attach a Black Rapid strap to the camera so I can switch quickly from hand held to tripod. That sounds like precisely what I'd like to do, but I'm not actually sure I follow HOW this product helps Bill achieve that goal. How does the BlackRapid fastener fit into this equation, for instance? What am I missing..?2. I'm also planning on buying this clamp to replace the mini arca quick-release system on my MeFoto DayTrip tripod, in order to have consistent quick-release plates on all my tripods. So really, I'm just deciding whether I should buy one or two of these little guys. But I'd love to know if my plan for adapting my MeFoto tripod head won't work for any reason.Thanks!

A: Unfortunately, we are not sure what Bill in Georgia specifically is using, nor do we have the ability to inquire as to what type of setup he has made. However, Custom SLR produces a plate that is both Arca and Manfrotto compatible that would enable you to use a BlackRapid strap in conjunction with this clamp: http://bhpho.to/1tNH3SGAs for your second question regarding using this clamp with the MeFoto DayTrip, this is compatible.

Q: 5. What difference between this one and the DDC-60i model? Thx.

A: Sunwayfoto DDC-60i Screw-Knob Clamp (60mm) has safety stop grooves. Sunwayfoto DDC-60 Screw Knob Clamp (60mm) does not have that feature.

Q: 6. Does this work with the Peak Design plate attached to the camera?

A: Yes, the Peak Design PL-S-3 Standard Plate and the Peak Design Dual Plate v2 for Capture Camera Clip should be compatible for use on the Sunwayfoto Macro Focusing Rail with Screw-Knob Clamp.

Q: 7. Can this rail be used as a nodal rail for panoramas?

A: No this is for macro use

Q: 8. Some similar product list bearing capacity, in pounds. How much weight can this item handle?

A: The manufacturer does not list a weight limit for the UURig R060 Super Crab Clamp (B&H# UU2220). That is sometimes because of the great variety of possible configurations and contexts in which it could be used. However, the weight of the items shown in the photograph with the heaviest setup totals about 5 lb. (2.2 kg).

Q: 9. Can this clamp be mounted on another clamp to be used to change the direction of the rail's orientation?

A: Yes, this is possible, but depending on what equipment you plan to mount and the knob size on the other clamp, there could be interference, though many configurations should work.

Q: 10. How does the rail mount to tripod?

A: The bottom of the rail has standard threads for mounting (like any camera) but the entire rail itself is compatible with any arca-type mount and this allows you to move the entire rail back and forth.
