Hejnar H113 Replacement Foot for Canon EF 300
Hejnar PHOTO line of Arca-Swiss® dovetail compatible collar replacement feet for telephoto lenses has been extended with a new model.

The Hejnar H113 Replacement Foot carries the same design characteristics with the Hejnar H110 as mentioned in the beginning. It is precision CNC machined out of a solid Aluminium block with a curved and textured non-slipping top acting as a grip in order to facilitate carrying the heavy Canon lens. Nevertheless, the front part provides a flat double dovetail section in order to accommodate a flash bracket or any Arca compatible device with a clamp. Unlike other makes the collar mounting block is almost solid for better vibration absorption.

The H113 bottom is deeply carved with only a central brace, where two tapped holes lay side by side for direct mount on any kind of pod with an equivalent stud. One hole is threaded 1/4"-20 and the other 3/8"-16. Two M3 safety stop screws are also provided one at each end of the foot.

As on all Hejnar rails, the H113 replacement foot dovetail dimensions are compatible with Kirk®, R.R.S.®, Arca-Swiss®, and many other Arca-Swiss style Quick Release clamps.

It is very easy to replace the factory installed lens collar foot. All is needed, is to completely unscrew the four mounting screws of the original Canon foot using the Allen hex key included with the H113 and  remove it.
Then using the same four original Canon screws, screw and secure the Hejnar H113 replacement foot onto the lens collar. In order to avoid screw slack, it is recommended to use a thread locking compound like Loctite 242 (blue) or any other equivalent medium strength product.
