How it works
The Dorma BTS 75 V pivot installs beneath the door's swing axis. It uses an internal hydraulic mechanism with adjustable settings to control the speed, final snap action, and optional hold-open at a precise angle. When opened past a set point, it retains the door open until manually moved. Its concealed placement ensures functionality without visual intrusion on interior or exterior design[5].
