The Kirk SQRC-3157 Quick-Release Clamp fits into the RC2 quick-release element of a Manfrotto head to convert it to an Arca-style quick-release system. This lets you "recycle" an existing three-way or ball head so you can remove and attach your camera more quickly. With just a quarter-turn of the sure-grip knob, the SQRC-3157 enables you to release the plate by sliding it; with a full turn, you can remove it upwards.
The SQRC-3157 is compatible with most Arca-style plates and mounts. Constructed of a rugged aluminum alloy and anodized to a scratch-resistant finish, the clamp features a bubble level as well as notched lines that indicate the position of your sensor's center, which enhances the precision of such tasks as panoramic photography.

Hi quality and perfect fit. Holds my camera rock solid.
I purchased this product to allow me to use my older Manfrotto tripod and monopod's existing heads with my newer Arca-Swiss compatible camera and lens plates. I recently purchased an upgraded, sturdier tripod system and converted my gear to the Arca-Swiss standard plates. The Kirk Clamp/Adapter allowed me to use my new system on my older gear without having to replace the heads on all my lighter tripod gear. The base of the adapter fits perfectly into the quick-release Manfrotto heads and actually provides a tighter fit than the original Manfrotto plates. I can move the adapter from tripod to monopod very easily or remove it completely for travel. This product does exactly what I needed it to do and is made very well. The Arca-Swiss compatible clamp has a very smooth action, and the bubble level is an added bonus. I'm glad I found this product.
