Corbin Russwin 188F41-8-689 – Frequently Asked Questions

1) My door's top rail is too narrow to mount a closer the regular way. What do I use?
The Corbin Russwin 188F41 bracket exists for exactly that condition. It permits parallel arm or top jamb mounting on the door when the top rail is too narrow to install the closer in the regular manner, so you keep the closer on the door instead of relocating the whole job. It ships with the 691F78 spacer and five screws.
2) Does the Corbin Russwin 188F41 convert a regular arm closer to parallel arm mounting?
That is its purpose. The 188F41 is a mounting bracket that converts a regular arm configuration to a parallel arm closer installation. The closer body itself is unchanged; the bracket and the included 691F78 spacer reposition the arm attachment.
3) Is the 188F41 parallel arm bracket handed? I have both left and right hand doors in the building.
Non-handed, so one part covers both swings. The single model supports up to four mounting positions, push or pull side, door or frame mounted. For a property manager standardizing across a building, that means one bracket number on the shelf instead of two.
4) Will this bracket work on a 1-3/4 inch commercial door?
Yes. The closer application it supports is rated for 1-3/4 inch (44mm) standard door thickness, which is the usual commercial leaf. Recommended maximum interior door width is 54 inches and door weight up to 250 lbs with the spring adjusted across sizes 1 through 6.
5) Can I use this parallel arm setup on a fire rated door?
The closer application is UL10C positive pressure rated up to 3 hours and UL-cUL listed, so a parallel arm mounting is acceptable on a rated opening. What you cannot do on a fire door is the hold open arm. Hold open is available by specifying DC5200 x A1, and it is not for fire doors.
6) Does a parallel arm mount still meet ADA opening force and Grade 1 on this closer?
The closer is ANSI/BHMA A156.4 Grade 1 certified, ADA/ANSI A117.1 compliant, and TAA compliant. Adjustable spring power sizes 1 through 6 is what lets you dial opening force down to meet accessibility requirements on interior openings while keeping the Grade 1 rating.
7) What comes in the box with the Corbin Russwin 188F41 bracket?
Each unit ships with the parallel arm mounting hardware: the 691F78 spacer and five screws. The closer, the arm, and any drop plate or blade stop spacer needed for your specific frame condition are separate.
8) How far will the door open with a parallel arm compared to pull side mounting?
Opening range depends on which side you mount. Pull side gives 140 degrees; push side, which is where a parallel arm lives, gives 110 degrees. If you need the wider swing and the top rail allows it, mount pull side; if an overhead obstruction or a corridor condition forces the closer to the push side, the 188F41 bracket gets you there at 110 degrees.
9) Is there any vertical adjustment in the 188F41 bracket if my hole pattern is off?
1/2 inch of vertical adjustment is built in, which is usually enough to clear an existing prep or line up with a stop condition without redrilling the door. The arm is a spline arm with multiple indexing options, so you also have rotational adjustment when setting preload.
10) Is the 188F41 a cast bracket or stamped steel? I need it to hold up in a high traffic corridor.
The closer body is cast aluminum with a cam and roller design using Cam-Motion technology. It is a commercial rated part, carried for commercial rather than residential use, with backcheck standard on every unit to protect the door and bracket from being thrown open into a wall.
