Cal-Royal CR441 Surface-Mount Door Closer — Heavy-Duty Grade 1, Adjustable Size 1–6, Super Rigid Parallel Arm with Stop (No Hold-Open)
The Cal-Royal CR441 is a heavy-duty, ANSI/BHMA Grade 1 surface-mount door closer configured with a Super Rigid Parallel Arm that includes an integrated door stop and no hold-open feature. With adjustable spring power Size 1–6, independent closing and latch speed control, and backcheck, the CR441 delivers smooth, reliable operation on demanding commercial openings while protecting frames, hinges, and adjacent walls from over-travel.
Why the Super Rigid Arm with Stop?
- Integrated stop helps limit and cushion the opening angle to reduce impact damage.
- No hold-open detent — ideal for locations where hold-open is not desired or not code-permitted.
- Parallel arm (push-side) installation provides a low-profile, tamper-resistant setup.
