See here the principle of the MAGNETIC - CLAW - PROFIL.

The new awning cloth with the sewn onto KRAKE MAGNETIC - CLAW - PROFIL is put on head-on on the roller tube and aligned.

By slightly tightening the cloth, the claw profile will cling on the rim of the groove all the same which form the groove has.

No matter whether the tube is unvarnished, varnished or is powder-coated.

- Simply and brilliant!!
