See the images tab for details on mounting, finish and bolt hold alignment.
Tri-Pak Mounting Kit
This basically means the closer is furnished with a parallel arm bracket. When this bracket is used, the closer may be mounted parallel arm style. When not using the bracket, the closer can mount regular arm or top jamb mounting style.
The narrow body style allows the unit to mount to only 2″ of flat surface. This allows the closer to be used on both standard and aluminum storefront doors and frames.
When replacing an existing closer, first check the bolt hole alignment. This is the best method of ensuring you receive an exact replacement. Regardless of closer brand, use the bolt holes to determine the proper model number for replacing a closer.
The standard for meeting ADA requirements is 5 lbs. or less of opening force for interior doors, and 8.5 lbs. or less for exterior doors. Because conditions vary so much from one opening to another, you need a fully adjustable spring. This is provided with closer models 8301 and 8501.
When you need the closer to have the hold open feature, a different arm is furnished. The hold open is all in the arm and has nothing to do with the closer body. Examples of models that include the “H” hold open feature: 8301H, 8501-H
