What are lip profiles?
Lip profiles are quite similar to flap profiles. Where flap profiles have a flat flap attached to the base of the profile lip profiles have a lip at the end of the flap. This lip helps to secure the positioning of the seal during and after installation. Lip profiles are secured behind a metal retaining plate or strip, which is then fastened with screws or rivets.
Most of our lip profiles have a magnet chamber, which can hold a magnetic strip. DSU profile codes with an –M extension have a magnet chamber. There are a few lip profiles without a magnet chamber. These lip profiles have a profile code with the extension –R.
