Installing the Arrow DC500 Series Surface-Mounted Door Closer

Weight and dimensions of a door should be considered when selecting the right door closer. However, using a closer with adjustable spring closing force can eliminate most of the decision making process.

With the advent of adjustable spring closing force, choosing the “right” surface-mounted door closer for a specific door has become much easier. For example, a 3’0” by 7’0” interior door is a very common size for many commercial applications. Checking a closer catalog will usually recommend a number two or number three sized door closer.

However, choosing a door closer is determined by more than just the door width and height. The weight of a door is the most critical consideration, as the heavier the door the more force required to close the door.

Using a door closer with adjustable spring closing force can eliminate most of the decision making process. For most standard size and construction doors, whether they are installed for interior or exterior applications, an adjustable spring closing force door closer can be adjusted to operate.

Arrow Lock and Door Hardware has introduced their DC500 Series heavy-duty door closers, designed to meet the requirements of ANSI/BHMA A156.4, Grade 1 and the Standard UL 10C for self-closing, surface-mounted type without hold-open feature. DC500 Series door closers meet ANSI A117.1 requirements for ADA barrier-free accessibility of five pounds maximum opening force depending upon the application.

Arrow DC500 Series door closers have a cast iron body, with a hardened steel rack and pinion, and high tensile strength steel springs. There are three size-adjustable models: the DC516, DC514 and the DC525.

The DC516 has an adjustable spring for sizes 1 through 6. This door closer is designed to meet most door closer applications, as it can be adjusted to provide sufficient closing force for interior and many exterior door applications.

The DC514 has an adjustable spring for sizes 1 through 4. This door closer is designed for light through medium weight interior doors and light weight exterior doors. The DC514 can meet the five pound handicapped requirements.

The DC525 has adjustable spring for sizes 2 through 5. DC500 Series door closers have separate adjustment valves for sweep and latch, as well as backcheck.

These non-handed door closers are specifically packaged for mounting regular (standard), top jamb, and parallel arm when equipped with a standard arm or a standard hold open arm. The regular arm application has the closer body mounted on the hinge (pull) side of the door. The forearm is mounted to the frame face by a mounting shoe. The arm projects at a 90-degree angle away from the door. The regular arm application is used when there is no concern about the arm extending perpendicular from the door. The regular arm mount closer is more power efficient than either the parallel arm or top jamb mount.

The top jamb is a method for mounting the closer if the door has a narrow mounting area. For example, the top jamb method can be used for aluminum glass door with a narrow rail or a door with a large glass panel. The closer body is mounted to the frame face above the door, opposite the hinge (push) side of the door. The forearm is mounted to the door. The top jamb mount is more power efficient than the parallel arm application.

The parallel arm method is for mounting the closer having the arm parallel to the door. This mount style can limit vandalism by having the arm in close proximity to the door face, improving the overall aesthetics. The closer body is mounted on the door opposite the hinge (push) side. A parallel arm bracket mounts the forearm to the underside of the frame. The parallel arm mount is probably the least power efficient mounting application.

For this installation, I installed the Arrow DC525-1, an adjustable size 2-5 door closer with the standard Hold Open arm and Parallel Arm bracket onto an interior wooden door separating the manufacturing area from the offices. The hollow core door has a glass panel. The outswing door has a maximum opening of less than 90 degrees.

Important: For parallel arm installation, the Back Check selector valve must be closed (rotated clockwise to all the way in) before installation.
