Hardware for the Crown bifolding door has been specifically designed for the doors and is not proprietary hardware used on some other systems. An example of this is the unique Shootbolt & ‘D’ Handle.

Door leaves feature a rebated arrangement that is designed to provide improved weather performance and aid security.
The SAPA bifolding door can now be manufacture at up to 2500mm high.

Another benefit of the continuous hinge is that there is no hinge adjustment required.
For the fabricator, there is an integral cill option meaning less material required that keeps costs of materials lower with less aluminium to coat, fabricate and stock hold. Adjustable jambs giving +/- 2mm mean detailed site adjustments can also be carried out.
