Lapcon®: Dampening Technology for a High-End Soft Door Closer

The Lapcon® Door Damper (LDD) is a self-closing soft door closer that ensures swinging doors will fully close when they are pushed—adding convenience and soft-closes to eliminate stress and pinched fingers. Designed for interior swinging doors, the LDD soft-close surface mounted door closer engages at 15° from the closed position and gently closes the door on its own from there.

This page is for Model No. LDD-S-L/LBR (left-hand opening, light brown color). See the other LDD models in the series below. You can browse additional Sugatsune door accessories to explore all of the available options.
