Installation Clearance Requirements
If you intend to install your Stira Semi-Automatic system flush against a permanent structure in your loft space such as a wall, you’ll require an extra 40mm clearance on the motor side, and/or an extra 15mm clearance on the bearing side on the width. For the length, you’ll require an extra 40mm clearance at the motor end. All at a height of approximately 430mm above the trapdoor. This is to allow for these Semi-Automatic elements which protrude past the outer frame external width and length dimensions.
