Continuous Hinges

Unlike other doors, commercial doors open and close smoothly daily, without squeaking, drooping, or binding. A common denominator is continuous hinges, which are the workhorses of door frames and extend the whole length of the door.

Piano hinges hold the door at three little points instead of two, distributing weight equally across its height.  It's like having a hefty box with two fingers vs. your whole hand.  Which will last longer? Hundreds of times a day, busy business establishments open their doors, and this engineering advantage guarantees years of reliable operation and much cheaper maintenance expenses.

Continuous hinges are also called "piano hinges" because they initially supported piano lids.  Continuous hinges are heavy-duty commercial door hinges that benefit from ongoing maintenance and assistance. According to the Door and Hardware Institute, this design can minimise stress on each mounting point by as much as 75%.
