Hager 4501 CVR Concealed Vertical Rod Exit Device — Grade 1, Non-Rated, 36" x 84" Door
The Hager 4501 CVR is a heavy-duty concealed vertical rod (CVR) panic exit device built for high-traffic commercial single doors where a clean, tamper-resistant profile is essential. Engineered for 36-inch wide by 84-inch tall openings, this ANSI/BHMA A156.3 Grade 1 device routes both the top and bottom latching rods entirely inside the door edge — delivering superior vandal resistance and a streamlined look that surface vertical rod (SVR) hardware cannot match. As a Non-Rated (Panic Hardware) device, the 4501 CVR provides intuitive, code-compliant egress on non-fire-rated openings. Buyers comparing a concealed vertical rod exit device across brands will find the Hager 4500 Series a stable, service-friendly alternative to other CVR lines on the market.
Grade 1 Features & Benefits
- Two-Point Concealed Latching: Top and bottom rods and latch bolts are fully hidden inside the door, protecting the mechanism from tampering and abuse while providing positive door control on tall or exterior openings.
- ANSI/BHMA A156.3 Grade 1 Certified: Meets the highest commercial-duty rating for exit devices, suitable for institutional, educational, healthcare, and high-traffic commercial applications.
- Hex Key Dogging: Push bar can be held in the retracted position for push/pull traffic during business hours; dogging is permissible on this non-fire-rated configuration.
- Field-Reversible Handing: Non-handed chassis adjusts in the field for both left-hand and right-hand doors, reducing special-order delays on the jobsite.
- Rich Finish Selection: Available in six BHMA-coded finishes — 626 Satin Chrome, 630 Satin Stainless, 613 Oil Rubbed Bronze, 605 Polished Brass, 606 Satin Brass, and 625 Polished Chrome — to match virtually any architectural specification.
- Electrified Options Available: The 4500 Series supports a full range of electrical prefixes including Request to Exit (RX), Latchbolt Monitoring (LM), Motorized Latch Retraction (MLR), Delayed Egress (DE/OBDE), and Authorized Ingress (AI/RXAI) — making it a strong platform for electric concealed vertical rod exit device applications.
- Vandal-Resistant Profile: Concealed rod design eliminates exposed hardware at the top and bottom of the door, significantly reducing the surface area available for tampering compared to SVR configurations.
Applications
- Commercial single doors requiring two-point latching without exposed surface rods
- Institutional, education, and healthcare facilities where aesthetics and tamper resistance are priorities
- Exterior or oversized doors that benefit from top-and-bottom door control
- Openings where specifiers seek a Grade 1 CVR device from a preferred, parts-stable manufacturer
