ProBox Install title

The ProBox installation jigs are designed to be positioned on the shaper’s marks on the board. Ensure that these marks are clearly visible and that a line has been extended through the front and back marks, this line should be longer than the installation jig.

The installation jig has a number of different lines along it’s center that are used to correctly position the jig depending on whether its a center or side box. Additionally, there is a small circular cutout in the jigs called the viewport, this is used to align the jig with the shaper’s mark. The viewport is offset slightly to the side of the centerline of the jig so that it can be aligned with the inner face of a side fin.

For a center fin installation the shaper’s mark must be extended at 90 degrees to the centerline so that it will be visible in the viewport. A drawing of the installation jig is shown pointing out all of these details.

Prepare the installation jigs and the board by spraying a small amount of adhesive on the underside of the jigs and on the bottom of the board. A cutout masking template can be made from a piece of cardboard or door skin, using the jig as a template. This template can then be used to spray the adhesive on the board to minimize over spray.

Allow the adhesive to tack up and then start attaching the jigs to the board. For side boxes the jig must be positioned with the arrow and “R” pointing to the rail. The offset centerline is used for the side boxes, the viewport is centered on this line.

Place the back viewport over the back shaper’s mark aligning the jig on the mark by looking through the viewport. At the front end of the jig simply align the offset centerline on the extended line. Ensure that the jig is pressed down flat on the board. The procedure is the same for a center box except the centerline is used. The photo shows a correctly attached rail jig.
