Product Introduction

The face-fixed seal mounts as a complete linear housing against the lower door face. Its automatic mechanism lowers an elastomeric sealing element when the door closes and withdraws it during opening. The accessible carrier allows installation without the deep internal groove required by a fully mortised unit. Independent levelling adjustment helps the seal follow the threshold, making this arrangement useful when an existing door needs a practical bottom-gap upgrade.
