Case Closed: Meet the Lapcon® Commercial & Residential Door Closer

The Lapcon® Door Damper (LDD) is an industrial, commercial, institutional, and residential door closer which ensures that swinging doors will close gently and securely on their own. This is a great productivity feature for bustling workplaces as well as a luxury feature in hotels and conference centers.

Designed for use with interior swinging doors, the LDD takes hold of the door at 15° from the closed position and softly closes the door from there, even if the user pushes the door hard (within reason).

This page is for Model No. LDD-S-R/DBR (right-hand opening, dark brown color). See below for other models, which feature a variety of colors as well as the corresponding left-handed versions. For additional options, visit our Door Accessories department.

LDD Commercial & Residential Door Closer Features

An Eye Toward Functionality, Durability, & Performance

  • The LDD is easy to install on either new or existing doors, with installation optimized for speed and convenience.
  • The sturdy steel construction, high-precision design, and cycle-tested Lapcon® dampers all contribute to a product that will be durable and high-performing.
  • You can adjust the damper for door weight post-installation in order to maximize the LDD’s self-closing operation.
  • The damper function can be easily disabled whenever needed.

Generous Door Compatibility Specifications

  • The LDD commercial and residential door closer has a slim vertical profile of only ¾”, fitting into most door frames.
  • Safely supports doors up to 36” (914 mm) in width.
  • Designed doors weighing 33 to 88 lbs (15 – 40 kg).
  • The design is handed, so make sure to buy left-handed or right-handed models as needed.
  • For use only on interior doors, as exposure to water, high humidity, wind, and extreme temperatures will degrade the mechanism.
