OPTIONAL ACCESSORIES
Doors are available with a variety of Specialty Options for specific installation needs. Contact Factory for additional options.
Swing-Up Sectional Post A perfect answer for openings that are too large for a single overhead door that must accommodate large machinery or equipment on an infrequent basis. Operating on a single pivot point that is designed to swing left or right, it allows the use of one (1) smaller door for everyday requirements and the full opening when needed. See video.
Pass Doors Whether it’s for convenience or necessity, there are circumstances where a pass-through door is requested to provide ingress and egress in an overhead door enclosed opening without having to open the overhead door. C.H.I. can accommodate this need with a state-of-the-art design pass-door option. Available in our urethane core models 3216 and 3212, it’s the ideal choice to solve this need.
Header & Jamb Seals Seal the perimeter of the opening to provide additional air infiltration and thermal protection.
CERTIFIED WINDLOAD
Wind can be unpredictable and destructive. This is why C.H.I. Windbreaker Series and iSeries doors are designed, tested, and built to the most rugged specifications. Wind chamber tested to ensure windload resistance, these extra-sturdy designs provide enhanced defense against the elements.
C.H.I. Overhead Doors developed the resilient Windbreaker Series garage doors to protect against high wind conditions. The super-resilient C.H.I. iSeries Impact Approved doors have strength designed to withstand direct collision of projectiles and other windborne debris at high speeds.
Additional Windload Information:
Navigating the complex windload codes and compliances can be a daunting task. C.H.I. sales associated and distributors are able to help you understand the specific codes governing your geographic area. For additional information, these websites offer a great deal of information.
