Soft-Close Lift-Up Flap Door System — SF Series
Product Overview
The SF Series lift-up mechanism turns upper cabinets into effortless, handle-free storage. A calibrated spring-assist core raises the flap door smoothly to a 107 ° opening angle, holds it at any position, and returns it to a gentle, silent close. Three-way post-installation adjustment (height ±2 mm, side ±1.5 mm, tilt ±2 mm) guarantees millimetre-perfect alignment in premium kitchens, offices, and bathroom wall units.
