Frame anchoring
In order to achieve a maximum load capacity, it is necessary to anchor the frame within
100 mm / 4" above and below the upper hinge, plus in other areas as needed.
Door closers
When overhead door closers are used, SIMONSWERK recommends the use of a
third hinge in the upper third of the door. The correct adjustment of the closer is a
fundamental requirement for a long-lasting, problem-free functioning of the door unit.
Powered door openers
When a powered door opener is used, SIMONSWERK recommends using four hinges
placed in two pairs at the top and the bottom. Using the recommended hinge location
of 250 mm / 10" from the top and 250 mm / 10" from the bottom, the additional hinges
should be placed 350 mm / 14" below and above the upper and lower installed hinges.
Closing sequence control systems
When closing sequence control systems are used with double-leaf doors, it is important to
ensure that a cushioned closing device is used for the active door leaf, so that the forces
are not directly transmitted to the hinges. In this case, SIMONSWERK recommends using a
third hinge in the upper third of the door.
Wall openings, door stoppers
If it is necessary to use a door stopper, this should either be mounted on the wall or,
instead, on the floor placed at 75 % of the door's width away from the hinge axis in the
direction of the lock.
Miscellaneous
This information is only a guideline and other factors such as door material, door width,
usage level, location, and environment might alter these. Therefore, it is suggested to
contact SIMONSWERK for recommendations.
