Brand new aluminum camera riser 

Here's the details : 

- Slightly wider distance between 2 of the 4 posts to easily access the nut.
- Anodised in black for durability. All surfaced are machined and chamfered.
- Black zinc plating on the steel nut.
- That nut is made from steel for durability and has 4 embedded tabs on top of its petal form for grip.
- Dual entry threads, which means faster screwing and unscrewing time. Every second counts.
- Stainless Steel hardware.
- Mitchell mount on top and bottom.
- Dual locating position for the head
- Stable, as you can imagine.

Made in Canada, with great attention to details.

This is for the 6" one. I do have 4, 6, 12 and 24" risers, and can also make them the height you desire. 
I do work in the film industry. This is my take to upgrade the basic riser we all use.
