Modular lens support

Original Design 

Many of you are using lens support brackets with lens/camera combos. In this combo the distance between lens barrel and mounting surface (either lens foot or camera bottom)  is limited. When the lens is equipped with a tall lens foot, there is no problem using the clamp on the rail. This provides for quick height adjustment, handy if you change lenses often. If you mount a clamp on the rail end, your lens foot is closer to the lens barrel and you will have problems with lowering the bracket. This is happening because the V groove on the LLSB side does not run the full length. The solutions until now were to either
             1) Increase distance by using dual sided clamp (or clamp set) between camera or lens foot and     vertical mounting rail.
             2) Use 90 degree connector mounted under horizontal rail for clamp mount
             3) Use center slot and screw mount option  instead of clamp. But L wrench needed to adjust height.

I was trying to make this bracket work for everybody, but no matter how I designed it there was some kind of problem. Finally, I decided to make this two part assembly where you can mix and match the wheel section and the rail itself.  Now you can have a shorter 2 inch, longer 3 inch, or any other rail you may need. Rail has V slot along hole length. On the top of this rail I can mount a wheel section. Again, the wheel section can be now wide or narrow and tall or short. I didn't produce many different wheel section designs, but they are going to be available soon.
Combinations are endless and you can match them to any lens/camera combo.
I can also make a smaller wheel diameter to allow you to bring your lens closer to the rail.
Rails ( 3 and 2 inch)

Wheel section. Wheels are equipped with soft rubber 

Wheel section and rail mount using two screws 

You can use 1.5 inch clamp on rail end 

Distance between horizontal rail and lens barrel will shorten if you use 1 inch clamp on rail end instead of 1.5  inch.

Clever modular design. Much better having the option of a shorter support which is what I am searching for using a low profile lens foot. Do you have an ETA on availablility?
