Hager 4701 SVR FR Exit Device - Fire Rated - 4'0"x 7'0" Door
The Hager 4701 SVR FR Exit Device (48" x 84") is a heavy-duty, fire-rated security solution engineered for wide commercial door openings. While standard 36" devices cannot provide the necessary coverage for oversized entryways, this Surface Vertical Rod (SVR) system is factory-sized for 4'0" widths, providing the essential leverage and reach required for wide fire-rated corridors, school double doors, and hospital exits.
As a BHMA Certified Grade 1 device, the 4701 SVR FR represents the highest industry standard for mechanical durability. It is UL/cUL Listed for up to 3 hours on fire-labeled doors, serving as a critical life-safety component that ensures a secure seal against smoke and flames. This model is Less Dogging (LD) as mandated by fire codes, ensuring the vertical rods are always engaged and the door is latched at all times.
Enhanced Security for Oversized Fire Doors
Wide fire doors are susceptible to heat-related warping; the Hager 4701 SVR FR mitigates this risk by anchoring the door at both the top strike and the floor. The stainless steel Pullman-style latchbolts provide a smooth, automatic dead-latching action that secures the door instantly upon closing. To handle the increased weight of a 48-inch fire door, this device ships standard with thru bolts, providing a high-strength through-the-door connection that ensures the hardware remains permanently aligned.
Key Features
- Fire-Rated Compliance: UL Listed for use on fire-labeled door assemblies up to 3 hours.
- Wide Door Optimization: Sized for 48" (4'0") door widths; can be field-cut for doors down to 37".
- Grade 1 Performance: BHMA certified to withstand heavy commercial use and high-frequency cycles.
- Multi-Point Latching: Dual latching points at the top and bottom provide maximum resistance against prying.
- Non-Handed Design: Reversible in the field for use on both left and right-hand swinging fire doors.
