Hager 4501 SVR Exit Device - Non Rated - 4'0"x 7'0" Door
The Hager 4501 SVR is an extra-wide, heavy-duty Grade 1 Surface Vertical Rod exit device specifically designed for 48" x 84" (4'0" x 7'0") commercial doors. Engineered for high-traffic double-door applications where a center mullion is not required, this panic bar provides secure two-point latching at the top and bottom of the door leaf. As a Non-Rated (Panic Hardware) device, it is the ideal choice for oversized secondary exits in schools, convention centers, and large retail warehouses.
Maximum Security for Extra-Wide Openings
Designed to accommodate the increased weight and width of a 4-foot door, the Hager 4501 SVR ensures the opening remains stable and secure. The top latch utilizes a stainless steel Pullman-type bolt for consistent engagement with the strike, while the bottom rod secures into a floor-mounted strike. For facilities requiring high-frequency passage during business hours, the device features hex key dogging, allowing the push bar to be locked down for effortless "push/pull" operation.
