Designed for use with compatible locking systems, the SMOO 44-03 backplate delivers the same essential function as the Truth Maxim LP® Backplate. When installed alongside SMOO locks or replacement hardware, this backing plate helps improve compression of the gasket during installation by spreading the clamping pressure of the lock mounting screws evenly across vinyl window profiles.Whether you are replacing Truth Maxim LP® components or specifying new hardware, the SMOO 44-03 backplate provides a direct, reliable solution that ensures a secure, consistent seal and helps maintain the long-term performance of the locking system.
