PIERMAGNET is basically similar to the DSLADJPROFILE

This closing profile is used on recessed only installations, this allows the customer to hide any imperfections when the glass sliding door meets the wall. 

To install the magnet. 

Customer would put the PI0000015 (push fit) seal onto the glass door and add the closing magnet PI0000016, fitter would remove the red adhesive sticker and simply close the door. By closing the door with the magnet attached it will leave the magnet in a perfect position matching the door, and neatly within the closing profile. 

Same applies without installing the closing profile.
