Discover the Lapcon® Self Door Closer

The Lapcon® Door Damper (LDD) is a self door closer that makes door operation easier and more convenient by ensuring that doors close smoothly and securely when pushed.

Designed for interior swinging doors, the LDD takes hold of the door at 15° from the closed position and softly closes the door from there, regardless of how light or strong (within reason) the user has pushed it. There’s no more slamming, and no worries about doors being left ajar.

The LDD self door closer is ideal for bustling work environments, luxury spaces, and institutional settings. It saves time, improves workflow, and adds a premium or professional factor to the setting.
