Selection guidance
How should the configuration be selected?
Confirm the exact model, clear opening, opening hand and car-door or landing-door application. Check the sill, mounting and door-head interfaces against the applicable drawing.
Can a photograph confirm replacement compatibility?
A photograph identifies the illustrated mechanism. Confirm dimensions, opening arrangement and the required electrical or mechanical interfaces for the specific replacement before ordering.
Do the drawings apply to every model on this page?
Each drawing is labelled with its own model. Use the corresponding model and opening range when checking dimensions.
