Description
Sugatsune LDD door dampers deliver premium quality soft, silent close motion for interior doors. Fitted with the groundbreaking LAPCON rotary damper technology, LDD dampers ‘catch’ a door late in its arc to bring it to a controlled close. This avoids the need for the conventional closer arm usually found on interior door soft close mechanisms, making the LDD a much more discreet and tidy option.
Easy to install and adjustable once in position to give precision control, LDD dampers guarantee safe, no-slam closing for doors weighing up to 100kg.
