Sargent 624 Bottom Strike for 8700 Series SVR Exit Devices

The Sargent 624 Bottom Strike is a replacement floor strike designed specifically for use with Sargent 8700 Series Surface Vertical Rod (SVR) exit devices. Surface vertical rod exit devices rely on two-point latching — a top bolt that engages the frame header and a bottom bolt that drops into a floor strike. The 624 provides the floor-level engagement point that completes that two-point latching system, ensuring secure, code-compliant door latching on every cycle.

This strike is finished in Black, making it a practical choice for installations where a dark finish blends with the floor or threshold area. As a genuine Sargent accessory, it is engineered to work seamlessly with the 8700 Series SVR device geometry and bottom rod bolt throw.

What Is a Bottom Strike on an SVR Exit Device?

On a Surface Vertical Rod (SVR) exit device, the bottom rod extends downward from the device body and terminates in a bolt that engages a mortised or surface-applied floor strike when the door is closed. The bottom strike receives and retains that bolt, holding the bottom of the door securely in the closed position. When the exit device push bar is actuated, both the top and bottom bolts retract simultaneously, freeing the door for egress. A worn, damaged, or missing bottom strike can result in a door that rattles, fails to latch, or does not meet fire door assembly requirements — making prompt replacement critical in any commercial or institutional building.

SVR Bottom Strike — Selection Notes

When replacing a bottom strike, verify compatibility with the specific exit device model installed. The 624 is specified for the Sargent 8700 Series SVR. For fire-rated assemblies, confirm the replacement strike is part of the listed assembly to maintain the door's fire label. Always consult the device manufacturer's template for correct floor prep and strike location prior to installation.
