Case Closed: Meet the Lapcon® Soft Close Door Damper

The Lapcon Door Damper (LDD) is a soft close door damper that ensures that swinging doors will close when they are pushed—improving safety and convenience while eliminating pinched fingers. Doors will close smoothly and gently in both heavy and light use.

Designed for interior swinging doors, the LDD soft closing door closer takes hold of the door at 15° from the closed position and softly closes the door from there.

This page is for Model No. LDD-S-L/DBR (left-hand opening, dark brown color). See below for other models. Browse our other door accessories if you’re looking for a slightly different application.
