No. Whether it is a traditional side jamb, splayed, or any other H&B UL labeled side jamb profile, all can be used - Is there a traditional head jamb that will protrude from the entrance?
No, while the entrance installs similarly to a traditional entrance there is no traditional head jamb - Are there special considerations that need to be accounted for when using H&B Infinity Transom Hoistway Entrances?
