In 1876, Mr. L. C. Norton was sent to Boston, Massachusetts to help build the Boston Trinity Church. The church was located on the Back Bay facing south and west - at times encountering some very severe wind conditions. When the church began operation in 1880, the pastor, Rev. Brooks and his congregation quickly found out that the strong winds would force the doors close with a thunderous bang. Mr. Norton’s attempt to remedy the situation was to hang the doors on double-spring hinges. He had now uncovered a second problem. The slamming stopped but now the strong winds made the doors stand open. One day, continuing to ponder the problem with the doors at the Trinity Church, he put some things away in a closet and being in a hurry, he threw the door shut. To his amazement, the door did not slam. Instead, the door bounced back. He tried this over and over with the same result. An idea came to him; he rushed to town and purchased a beer pump. With the beer pump, a makeshift arm, and some special brackets he had designed, Mr. Norton installed his invention on one of the exterior church doors. He opened the door and let it go...CRASH! The door slammed so hard it broke the pump into many pieces. Mr. Norton spent many months trying to solve the problem; finally, he used the principles of the lever, improved the main components, and decided to reposition the device on the door. He took his updated version and again installed it on one of the troublesome church doors. Rev. Brooks saw Mr. Norton’s new design and to his delight, the closer worked perfectly. Mr. Norton had used air pressure to make the doors close quietly. The problems with the doors at the Boston Trinity Church were now solved.

There are two types of surface closers, application specific and universal. On an application specific closer you need to specify right or left hand, and how the door closer is mounted, push side (parallel arm), pull side (regular arm) and top jamb. All of the 1000 Series are universal except if you have one of the heavy Cush, or EDA arms, then they have to be mounted on the push side (parallel arm). All of the 4000 Series are application specify, except for the 4040XP and 4030 closers.
Push side mounting is also called parallel arm, because the arm is parallel to the door when the door is closed. The LCN 4111 is a parallel mount only. Pull side mounting is also known as regular arm, the closer is mounted on the pull side of the door and the arm sticks straight out when in the closed position. The LCN 4011 can only be mounted regular arm. The last mounting is top jamb, meaning the closer is mounted above the door on the frame. The LCN 4020 can only be mounted top jamb.
