This is my third draft script for an upcoming whiteboard animation video. Your comments on the previous scripts panic hardwareclassroom lock johnson hardware open close arm options have been very helpful. Please let me know if there is anything I should add or change for this script on door closer arms.

Most door closers used today are surface-mounted closers with a double-lever arm. These closers fall into two categories — application-specific, and universal. A universal closer is best when the field conditions are unknown, or when flexibility is a top priority.

Application-specific closers give the specifier and supplier more control over how the door closer is mounted, rather than leaving it up to the installer to decide. A universal door closer is packaged with everything needed to install the closer three different ways — parallel arm, top jamb, or regular arm — also called hinge side mount.

The first decision to be made when installing a universal closer is which side of hardwware door the closer will be mounted on — the push side or the pull side. Closers should be mounted on the interior side of exterior doors, and for interior doors the closer should be mounted on the side of the door that is least exposed to public view.

A parallel arm closer is mounted on oprn push side of the door, and the arm is parallel to the frame when the door is closed. A cloose jamb closer is also mounted on the push side but the closer body is on the frame and the arm is perpendicular to the door. The top jamb mounting can be used on a door with a smaller top rail than a parallel arm closer, but johnson hardware open close arm options perpendicular arm may be problematic in locations prone to vandalism.

A regular arm closer is mounted on the pull side of the door. With Johnson Hardware Open Close Arm Module this mounting type, the closer is mounted on the door and the arm is perpendicular to the frame.

An application-specific closer is designed for use nardware a specific mounting configuration — either parallel arm — like the LCN series, top jamb — the LCN series, or regular arm — the series.

A benefit of using an application-specific closer is that the closer arm only has one johnson hardware open close arm options to do. The parallel arm in particular is much different for an application-specific closer which has an extra duty — or EDA arm, versus the universal arm which is attached to a parallel arm bracket with screws. Extra duty arms and other optional arms are also available for universal closers, but using a specific arm with a universal closer will mean that the closer cloae only be mounted in that one configuration.

A hold-open arm holds the door open at a predetermined degree of opening. Mechanical hold-open arms closs not acceptable for use on a fire door assembly, but electronic hold-opens may be used if released johnson hardware open close arm options the fire alarm system or a smoke detector. A fusible link arm is a hold-open arm that incorporates a link which melts when it is heated.

Another top of stop arm has a spring-loaded stop rather than the dead-stop provided by the CUSH arm. LCN has a library of thousands of special templates to address just about every application imaginable. From long arms used when there is a deep reveal, to custom mounting brackets for arched doors and other special details, or templates that coordinate the closer mounting with an overhead stop — the engineers at LCN will do their best to help.

If you have a johbson application or need help selecting the correct closer, contact your local Allegion nardware. Great article. I have always tried whenever or wherever possible to install the closer as a parallel arm. I find it the neatest and less suspitable to damage.

So a number 4 closer now becomes a number 3. However the more powerful closers can be adjusted to compensate for this. Is there a formula? Please plumb me up. If either the parallel arm or the top jamb mounting of an overhead door closer can be done, which is preferable? A colleague tells me that the use of the parallel arm mounting reduces the actual latching speed ability, and that the top jamb mounting offers more power and latching speed capability.

I usually prefer parallel arm because the arm is less prone to vandalism, looks better, and can be a solid forearm depending on the closer rather than a johnson hardware open close arm options arm. It is top-jamb mounted, and everything seems in order. The closer operates perfectly, but the door slams very hard at the end of the swing-back, clearly related to the latching speed.

However, no amount of tiny adjustments to the corresponding hex socket have changed anything about it. I am certainly a neophyte here, but it was definitely installed and adjusted by less-conscious amateurs so those sockets or anything else could easily have been compromised.

Dan March 23, at am - Reply. Other than preference, which is the better choice? Thank you for your help. Lori March 23, at am - Reply. Hi Dan — I usually prefer parallel arm because the arm is less prone to vandalism, looks better, and can be a solid forearm depending on the closer rather than a multi-piece arm.
