Hager 4701 SVR FR Exit Device – Grade 1 Fire Rated SVR for 4' x 8' Doors
The Hager 4701 SVR FR Exit Device (48" x 96") is a heavy-duty, fire-rated security solution engineered for the largest commercial door openings. Designed for doors up to 4 feet wide and 8 feet tall, this Surface Vertical Rod (SVR) system provides the structural stability and multi-point latching necessary for oversized fire-labeled entryways in hospitals, schools, and large retail complexes.
As a BHMA Certified Grade 1 device, the 4701 SVR FR represents the highest industry benchmark for mechanical durability. It is UL/cUL Listed for up to 3 hours on fire 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 to maintain the fire barrier's integrity.
Engineered for Oversized Fire-Rated Openings
Large fire doors are susceptible to heat-related warping and pressure; 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 and leverage of a 4-foot wide by 8-foot tall fire door, this device ships standard with thru bolts, providing a high-strength through-the-door connection that ensures the hardware remains permanently aligned and secure.
