Using a Split Batten Diagram

Split battens are a great way to fit your signs. They lift the panel away from the wall and support the weight of the sign without any external holes.

A sheet of MDF, timber or plastic can be used.

At the centre point, cut the batten at 45° using a mitre or ripping saw depending on the length of your batten.

Countersink the lower wall section so that no screw heads are above the plane surface of the lower split batten

Glue or screw the top section to the rear side of the panel. This will slide into the same cut on the lower section and create a powerful downward action forcing the panel into a tight position.
The split panel moves over the wall mounted section to lock in.
Once in Place, the sign is fixed.

Tips: If you use split battens close to the top and bottom lip of the outward panel, you can also screw down through the mitre with long screws to further bond the two sections.
Any later removal will require a drill and or screwdriver.
 

Both of these diagrams were put up on the wall using a batten system.

This diagram below shows a split batten system used for outdoors. Split battens spread the weight of the sign and the fitting becomes stronger than just screws or pop rivets. Two extra strong coach screws were used to prevent any gale force winds removing the panel.
