Discover the Lapcon® Interior Door Closer

The Lapcon® Door Damper (LDD) is a sophisticated interior door closer that ensures swinging doors close softly when pushed—making sure that doors actually close without requiring the user’s continued attention. They are great in fast-paced environments as well as luxury environments.

Designed for interior swinging doors, the LDD mechanism takes hold of the door at 15° from the closed position and softly closes the door from there, closing without slamming even if the door is pushed too forcefully (within reason).

This page is for Model No. LDD-S-R/LGR (right-hand opening, light gray color). See below for other models in this series, or visit our Door Accessories page if you’re looking for other solutions.

LDD Interior Door Closer Features

Performance Is Prioritized

  • You can install the LDD on new doors in upcoming projects or on existing doors in a renovation. The installation process has been streamlined for ease.
  • The damper is adjustable after installation so that it can be fine-tuned to the weight of the door it is attached to.
  • The damper function is optionally disableable if faster door-closing performance is desired.
  • Lapcon® dampers are precision-engineered, built from sturdy steel components, and cycle-tested—all with the aim of durability that provides value for many years to come.

Excellent Door Compatibility

  • The LDD interior door closer has a slim profile of only ¾” vertically, which means that it will fit in most door frames and work on most interior doors.
  • It is designed to safely handle door widths up to 36” (914 mm).
  • It is designed to safely handle doors weights ranging from 33 to 88 lbs. (15 – 40 kg).
  • The unit is handed for left- and right-opening doors, so be sure to order the appropriate models as needed.
  • Use on interior doors only, and avoid exposing the unit to water, high humidity, wind, and extreme high or low temperatures.
