Cal-Royal CR441 Surface-Mount Door Closer — Heavy-Duty Grade 1, Adjustable Size 1–6, Super Rigid Parallel Arm with Stop & Hold-Open, Parallel Mount Only, Aluminum Finish
The Cal-Royal CR441 is a heavy-duty, ANSI/BHMA Grade 1 surface-mount door closer configured with a Super Rigid Parallel Arm that integrates a door stop and manual hold-open function. Designed for parallel arm (push-side) mount only, it delivers a low-profile, tamper-resistant installation with adjustable spring power Size 1–6 to match a wide range of door sizes and site conditions. The clean aluminum finish complements modern storefronts and interior applications.
How the Super Rigid Arm with Stop & Hold-Open Works
- Integrated stop: Cushions and limits the opening angle to protect frames, hinges, and adjacent walls.
- Manual hold-open: Set an adjustable hold-open angle (project dependent) to keep the door open during peak traffic; disengage by moving the door past the set point.
- Parallel mount only: Push-side installation provides a clean appearance and improved resistance to abuse.
