Browse Door Closer Arm Parts

The parts that we carry for door closer arms include brackets, shoes, power tracks, studs, stud retaining rings, sliders and more. Arm brackets are one of the main arm related parts that we have in our inventory. 

In our selection of brackets, we have about eight unique styles of parallel arm brackets for door closers. If you require a parallel arm or bracket, this indicates that the closer should be installed on the door’s push side. When the door is closed, the arm should be parallel to it.

The Corbin Russwin Regular Parallel Arm Bracket is typically shipped out with their parallel arm mount closers. Another similar option would be the Corbin Russwin Hold Open Arm Parallel Bracket which is typically shipped when you order their hold open arm. 

This part differs from the aforementioned part in that it should only be applied with the hold open arm for parallel installations. See the product pictures to get a glimpse of what each one looks like.

We also have the International 525 Parallel Bracket. This is the bracket that will normally be shipped out with most of the closers from this brand. The other bracket option for this brand of door closer arms is the heavy-duty International 526 Parallel Arm Bracket which can be used with the Hold Open Door Closer Arm 522.

We also carry door closer arm brackets that were manufactured by Norton Door Controls. This includes the Norton Parallel Arm Bracket and the Norton Hold Open Parallel Bracket. These two door closer arm brackets can also be used with certain closers that were manufactured by the Yale brand.

Another option for door closer arm brackets that we provide are from the Sargent manufacturers. The Sargent Hold Open Parallel Bracket is for their hold open arms whereas the Sargent Parallel Arm Bracket 125-P should be used to convert the 25-O regular arm to a parallel arm mount.
