User Manual
NOTE: When using older Kirk screw-mount  
flash brackets, you must install the two extra  
safety stop screws in the counter-bored holes in 
order to keep the bracket from twisting on the plate.

Top Load 
(Required with Safety Stop screws) 
Safety Stop Channels We recommend using clamps with safety stop channels. 
These channels allow a full range of forward and back motion but will not let the 
plate slip out if the clamp is inadvertently loosened. 
Wimberley lens plates have a double dovetail cross-section. The 
upper dovetail allows you to attach Wimberley Flash Brackets as 
well as other 3rd party quick-release style brackets. 
Using Flash Brackets 
Wimberley plates are also made to accommodate older Really 
Right Stuff (RRS) and Kirk screw-mount flash brackets  
Your Wimberley foot comes with four safety stop screws and a matching hex key. Two of these screws are intended  
to be screwed into the small bottom threaded holes in the front and back of the plate (Fig. 6) to serve as stops that  
prevent the plate from accidentally sliding out of the quick-release clamp. If you opt to use both stops, you must  
open the jaws of the quick-release clamp wide enough to load your lens from the top (instead of sliding it in).  
Top Loading is less convenient,  
but you can be certain that your lens 
will not slide out of the clamp.

 3rd Party Clamp Warning: Our safety stop screws work with most 3rd party quick-release clamps, but clamps that do 
not have channels and are too wide to be straddled by the safety stop screws will not work. 
Arca-Swiss Z1 
The safety-stop security  
feature of this plate does not work  
when used with an Arca-Swiss  
“double-decker” quick-release clamp.  
If this plate safety feature is important to you, we recommend 
replacing the clamp with a Wimberley C-12 QR Clamp.
