High performance doors are the primary answer to many problems including mitigation to blast, ballistic, and forced entry events.  The construction methods of these doors and the addition of heavy-duty hardware creates an opening that is many hundreds of pounds heavier than most commercial doors.

High performance locks, hinges, and heavy-duty automatic door operators represent a significant investment in addition to the door and frame. Even in industrial environments, heavy doors will still need to operate within code regarding force to egress. The application of high-performance hinges and automatic door operators solve the secondary issue of accessibly but add complexity to the opening.  Service, maintenance, and repair to these components represent a tertiary matter that needs to be addressed when understanding the true cost of protecting a high-threat environment.

Doors which are designed to stop bullets, bombs, and bad guys have weight to them that normal openings don’t and are vulnerable to abuse by open and close operations.  The mass of these doors can put strain on closers, hinges, and automatic door operators if the door is forcibly opened wider than intended.  Whether it is heavy winds or an aggressive user, the door can hyper-extend and cause damage to components or could create years of problematic operations.

Floor or wall mounted door stops are vulnerable to damage by accidents and vandalism and may constitute a safety/trip hazard.  The Mico Overhead Stop by Surelock McGill was designed to “protect the protector” during openings by providing a cushioned, finite limiter on how far the door can open in a low profile, easy to install package.  The overhead stop will not allow the door to open past a set point and will protect your high value door accessories from abuse.

Our stop can be mounted to provide a range of 90 to 110 degrees of opening width.  The spring can be adjusted to provide varying levels of tension leading to the end of travel.  Both the medium and heavy-duty versions of the stop come in a variety of arm lengths to match nearly any width of door.  The low profile of the stop makes it perfect for integration with an existing automatic door operator or closer.

 The 316 Grade Stainless Steel construction of the stop will ensure operation even in the most extremely corrosive environments.  Surface mounting with machine screws are standard, but bolt-through options are available for doors that do not offer proper reinforcement.

Tremendous thought, care, and expense were invested in providing high performance doors and hardware to protect critical facilities from extreme threats.  Consider adding a Mico medium or heavy-duty door stop to your opening to add the final layer of protection for the door, hardware, and accessories.
