Application

For counter flaps at bars, restaurants, and receptions.

Description

Particularly suitable for counter flaps at bars, restaurants, and receptions, the ‘soft down’ motion-control of Lift-Assist Dampers provides smooth, safe-closing motion and is adjustable to suit the weight and size of different flaps.


Lift-Assist Dampers (LAD) are fitted with patented soft close technology that ‘catches’ a flap late in its closing arc, preventing slamming and making even the heaviest lids and flaps feel lightweight as they are eased to a close. They also work the other way, with lift-assist torque helping with upwards motion.


LAD dampers can be retrofitted to units without having to replace existing hinges.


Features and benefits:


  • Prevents slamming and brings even heavyweight flaps to a controlled, smooth close.
  • Lift-assist makes counter flaps feel light and easy to lift.
  • Easy to retrofit to existing counter flaps.
  • Discrete appearance with thin profile and minimal protrusion when opened.
  • Successfully passed 100,000 open/close cycles in a private test.
  • Free stop motion.


Variants:


LAD (LAD-H, LAD-L, LAD-M)


  • With stopper.
  • Suitable flap thickness: 15 - 25 mm.

  • Built-in damper provides soft closing near closing radius, preventing slamming.
  • Lift-assist makes counter flaps feel light and easy to lift.
  • Easy to align installation position using the included template.
