BEST B44194 Deadlocking Lever Spring | 40H Series Mortise Hardware | Package of 10

The BEST B44194 (#16 in the above part illustration) is a genuine, factory-specification replacement Deadlocking Lever Spring designed exclusively for the BEST 40H Series Mortise Locksets. This precision-engineered spring is a vital internal component that ensures the lever return mechanism and deadlocking functions operate with the tactile snap and reliability that the BEST 40H Series is known for.

In high-traffic commercial or institutional settings, internal springs are subject to millions of cycles. A fatigued or broken B44194 spring can lead to "lever sag," where the handle fails to return to the horizontal position, or a failure in the deadlocking logic of the mortise case. Replacing this component restores the lockset to original factory performance without the expense of replacing the entire mortise body.

Engineered for Institutional Durability

The 40H Series is the gold standard for heavy-duty mortise locks in hospitals, universities, and government buildings. The B44194 spring is manufactured from high-tensile spring steel to withstand the constant stress of daily use, ensuring that the deadlocking feature—which prevents the latch from being retracted by external force—remains fully engaged when the door is closed.

Technical Specifications

Why Choose the Genuine BEST B44194 from Doorways Plus?

At DoorwaysPlus.com, we recommend using only genuine BEST replacement parts to maintain the Grade 1 rating and fire certification of your hardware.

• Exact OEM Fit: Unlike generic aftermarket springs, the B44194 is designed to the exact tolerances of the 40H mortise case, preventing internal binding or premature wear.
• Safety & Security: This spring supports the deadlocking function. A functioning spring ensures that the latch remains "deadlocked" against shimming or loiding attempts from the outside.
  
• Cost-Effective Maintenance: Repairing the internal mechanism of a mortise lock is a fraction of the cost of a full unit replacement, extending the lifecycle of your existing investment.
• Reliable Lever Return: Eliminates lever sag, ensuring your doors remain ADA Compliant and visually aligned across your facility corridors.

Maintenance Tip: If you are experiencing a "floppy" handle or the lever is sticking in the down position, the B44194 is the primary component to inspect during your lockset teardown.
