Case Closed: Discover the Lapcon® Adjustable Door Closer

The Lapcon® Door Damper (LDD) is an adjustable door closer that ensures that swinging doors close softly and securely, adding luxury, convenience, and safety to any setting.

Designed for interior swinging doors, the LDD engages at 15° from the closed position and softly closes the door from there, regardless of how hard or gently the user pushed it (within reason). No more slamming and no more doors that remain ajar.

This page is for Model No. LDD-S-R/LBR (right-hand opening, light brown color). See below for the other models in this series, including different color and handedness options. For different door close and damper solutions, browse our other Door Accessories to see what Sugatsune has to offer.

LDD Adjustable Door Closer Features

Functionality, Durability, & Ease of Use

  • The LDD is easy to install on both new and existing doors and frames.
  • You can also easily adjust the damper after installation to better match the door weight for optimal self-close action.
  • The damper is optionally disableable, giving you more control over door performance.
  • Lapcon® dampers are cycle-tested and steel-built for durability under realistic use conditions.
  • Our smart design and precision engineering ensure premium-level performance for the end user, which is great for bustling business settings and luxury environments alike.

Compatible with Many Doors & Frames

  • The LDD adjustable door closer has a slim vertical profile of only ¾”, allowing it to fit into most door frames.
  • We’ve designed the LDD for door widths up to 36” (914 mm).
  • You can safely use it on doors weighing 33 to 88 lbs (15 – 40 kg).
  • The LDD units are handed for left- and right-opening doors, so be sure to order the proper model numbers as needed.
  • The LDD is for use on interior doors only, and should never be installed in environments with exposure to high humidity, water, wind, and temperatures extremes.

In addition, we supplement that line with a heavy-duty recessed type designed for use on heavy doors weighing 88 to 220 lbs (40 – 100 kg) (LDD-V100 Series)—ideal for many institutional and industrial settings.
