Many different attempts to trip a lens shutter deep in a recessed lensboard have failed, but the Gepe-Pro Flexible Cable Release finally solves the issue. The thread nipple is incredibly small, allowing even the shortest of lenses mounted in double-recessed lensboards to be easily accessed. Works on Copal 0 shutters mounted in Linhof Technika boards.

There are some shutters(such as Seiko) which have an angle of thread attachment that prohibits their mounting in a 96 x 99mm Linhof Technika-type board while having anything attached to their shutter.
