I have been doing work for a cafe that has issues with its entry door. The door is 4' wide, solid wood / half glass. The main problem is that the cafe is located on a two-lane north/south running street that has a tendency to turn into a wind tunnel. The entry door opens to the exterior perpendicular to the street so any wind blowing tends to catch the door and take it away. Being 4' wide and solid wood, the door has done much damage to itself the property and some of the patrons who attempt to open it on windy days. I have installed a hydraulic closer rated for this type of door without success. The wind caught the door the other day and broke the crash chain in half then door broke the stop installed on the ground outside in half. This is the second time the crash chain has broken. If i adjust the closer to require more force to swing the door customers will have a hard time. What should i do? Is there a way to play with the closer settings to accommodate this or is there another system I should consider? Thanks for any feedback.
