What should be done if the on-site measurements do not match the drawings?

We develop customized solutions tailored specifically to the client's actual wall thickness, thereby ensuring that our products align perfectly with the on-site dimensions. To guarantee this precision, we present these specifications across multiple dimensions—within our quotations, contracts, and technical drawings—to ensure that every parameter and detail precisely matches the client's requirements. In instances where the client's site may involve potential future modifications, or where the exact wall thickness remains undetermined, we offer our "Adaptable Frames" aluminum-wood door frame system; this allows the client to make on-site adjustments to the frames based on the actual wall thickness. Furthermore, we include CAD detail drawings with every shipment to ensure that the installation team can intuitively understand the instructions at a glance.
