The Rocket Anchor snaps into place (left).  Three popular boxes showing mounting options.

Sheath

This box with a highly contoured body may be a little more challenging still mounts with the same proceedure by trimming the support rim for best fit.  The result proved to be solid and trouble free even when having to split the case to fish out the string.  Notice one screw inserted to maintain alignment while drilling the second hole.

Even Difficult Mounts Are Possible

These photos show typical mounting using screws and nuts provided.  The support rim on the bottom can be easily shaped to fit the contour of almost any chalk box.  Mounting the sheath on the Starrett® box shown below does not require any trimming.
