This is new Hejnar Photo Quick Release 6.50 inch rail. Main purpose of this rail is to help you convert standard clamp from different manufactures into rail/clamp combination. Something similar to rail with integrated clamp.
Couple of months ago I had request to make rail with integrated clamp but clamps had to be wider than 1.5 inch since some cameras and L bracket do not work well with 1.5 inch clamps(camera to big, L brackets has a special cut for battery door opening -Nikon D40 for example). Instead incorporate wider jaws I decide to make a rail where you can mount clamp you already own and save some $$$$.
At the same time somebody else was asking for making jaws higher above rail level. He was using short lens and could see end of rail in his lens. Sure I could do that or make rail shorter. Instead making couple of expensive products I decided to make something much less expensive and as universal as possible.
This rail is what we decided to do. If you have clamp from any manufacture you can mount it on rail. If you want clamp go higher just use 1/4 spacer block ($ 14.99 at my e-bay store) and you are there.
I do provide 2 dowel pins with rail. They prevent clamp from twisting . If you own clamp with grove it will help placing pin(s) in rail hole and align with grove on clamps. My own Hejnar Photo clamps incorporate extra holes for aligning clamp on rail and preventing it from twisting.
Some clamps you will have to mount without pins. They do not have any opening where anti twisting pins can be located. In that situation you can use index stop bar ( sold separately)to prevent clamp from twisting. As you can see on pictures clamp can be place on rail in orientation where clamp knob is on back or on side.

It is the best quick release system for tripods and monopods when combined with Arca style ball head and quick release clamps. International standard dove-tail rail, compatible with Arca-Swiss type quick release clamps

All the corners and edges are rounded for the safety to prevent from accidental injuries or damages to the other equipments.
