FLM QRP-50 Quick Release Plate

There are two parts to your question that was submitted on the product page of the FLM QRP-50 Quick Release Plate (B&H# FLCP50). First, you asked if the FLM QRP-50 Quick Release Plate (B&H# FLCP50) is Arca Swiss-compatible. Our response to that is that yes, it is, and so it will fit in most Arca-compatible quick release clamps. Second, you asked if L brackets from Kirk and Really Right Stuff (subsequently referred to as "RRS") lock into the base. . . of something -- presumably of the FLM QRP-50 Quick Release Plate (B&H# FLCP50). No, they do not as this is a plate and not a clamp. However, as of July 2021, all L brackets made by Kirk or RRS that we currently sell follow the Arca standard and thus fit into most Arca-compatible quick release clamps. As such, if you were asking if those will fit into an Arca-compatible clamp then the answer is that they are indeed designed to do so. (There is some variance among manufacturers, however, so not every plate and clamp combination will always work even if they both claim Arca-compatibility.) If you would also like us to recommend a clamp, please contact us by email, chat, or phone and tell us what the clamp will itself be attached to -- such as to a specific of make and model of tripod head.

The currents FLM QRP-50 Quick Release Plate only have the brand, model and serial number engraved on the buttom of the plate. The threads on each side of the plate connected to a product that have been discontinued. FLM use to make an antitwist bar called FLM QRP-Stop.

The QRP plates are the most solid I've ever used, even with minimal tightening. This is partially due to the rubber-and-cork pads.
