Really Right Stuff B2-LR-II Lever-Release Clamp (60mm)

I like it for it is supposed to do -quickly and securely secure an Arca-Swiss plate, lens foot etc. The long lever gets in the way a bit when using with Wimberley MH-100 MonoGimbal head, but still functional. A recommended accessory.

I've known about RRS products for quite a while, but this is the first purchase of one of their products for me. True to their reputation, they are undeniably expensive - but for an excellent reason. The fit and finish on this clamp is top grade. The lever mechanism is very firm, leaving no question whether it's fully latched or not. But what I really appreciate is the perfectly smooth, rounded edges and corners. It makes holding and working with it an absolute pleasure. Could I have bought a similar clamp from a different company for much less? Of course. But I'm confident that buying from RRS means I only buy it once, and it will last longer than my camera or I will.

While I have this Really Right Stuff B2-LR-II Lever-Release Clamp (60mm) installed on all my tripods, monopod, Skimmer ground pod, multiple Platypods, and even on my Lenscoat LensSack Pro Beanbag because of the instant ability to change from ball head, to gimbal head, and in between my 400mm, and 600mm lens, or from horizontal to vertical perspective with the L-brackets on my cameras for landscapes, the part of my gear kit that has frustrated the living daylights out of me was the screw knob clamp on my Jobu Design Heavy Duty Mark IV Gimbal Head. While I love the quality and functionality of the gimbal head, I can't even begin to count the times I have missed birds in flight, or wildlife action shots because I was still turning this knob while the action was already all over. My original plan was to replace the horizontal piece of the gimbal head with the Really Right Stuff PG-CC Cradle Clamp for Gimbal Tripod Heads, however because it has been backordered for what seems like forever, I began thinking about alternatives that would provide that same functionality, and then it hit me that I could just mount a Really Right Stuff B2-LR-II Lever-Release Clamp on an ARCA plate and mount it on my gimbal head to get the same functionality. So I mounted my Really Right Stuff B2-LR-II Lever-Release Clamp on a 60mm Leofoto ARCA plate with Precision Scale to center the clamp perfectly on the plate, using a 3/8"-16 to "-20 Oben Reducer Bushing, and two "-20 Allen Head Socket Set Screws for added stability. Mission accomplished! I now have the instant functionality I desired from my gear, I won't miss anymore action, or birds in flight shots while fiddling with knobs, and my vocabulary won't be quite as colorful on my excursions. Thank you Really Right Stuff, kudos to , and yes Jobu Design I still love my Heavy Duty Mark IV Gimbal Head, especially now, that I won't have to fiddle with that cursed screw knob anymore!

This clamp is superb. I have had the RRS BH-55 ballhead for about 8 years. I got it with the screw clamp because that is the only type of clamp I ever used. The screw clamp worked great, but a lever is so much more convenient and quick. When I went to order this clamp, I noticed the underside had a rosette pattern. The top of my ball has a tongue and groove configuration. I was disappointed, believing the designed had changed over time and I was out of luck. After poking around, I discovered RRS makes adapters to match legacy equipment with newer designs. There is an adapter to match a legacy ballhead with a newer clamp (which is what I needed) or a newer ballhead with a legacy clamp. Each adapter is, in essence, the reverse of the other one. After using the lever clamp the last several week, it is a true pleasure to use and operate.

Great, secure clamp. You always know your camera is secure and never get confused as to which knob your loosening or tightening on a dark night. Web page description does not indicate but this model DOES include the 4-20 screws necessary to attach it to the head of your choice. I paired this with the Arca-Swiss monoball p0.

I damaged the clamp for my BH-50. This is a direct replacement and I couldn't be happier! Excellent quality from Really Right Stuff!
