The PVC protective hose can be used to install the drywall and tile profiles of the APTB series and APFL series. To do this, the required length of the hose is cut off and inserted into the profile. Once all tiling or drywall work has been completed, the hose is removed. This prevents filler, adhesive, sealing material, silicone, paint, etc. from penetrating the interior of the profile. The protective hose can then be easily cleaned and thus reused many times.
