Discuss this requirement ↗Describe the door application, lock type, cylinder requirement and access method. For replacements, include the existing model or measurements.
Identify the preferred appearance, fixing centres, spindle arrangement and intended door thickness. Finish matching is reviewed with the door design.
Provide the door material, estimated leaf weight, dimensions, handing and fixing arrangement. The required load and suitability need review.
Describe the intended use, opening direction and any specified accessibility, egress or fire-door requirements. The complete assembly needs compatibility review.
Tell us whether the hardware is for doors in your ZHONGKAI enquiry or for an existing door. Separate orders, replacement parts, samples and minimum quantities require confirmation for the selected item.
For an existing door, begin with the brand or model if known, door thickness, fixing dimensions, handing and destination. Photos and drawings can follow in direct communication.
Identify the parts, accessories, fixings and installation instructions needed. Ask the quotation to list included and excluded components.
Lock, handle, cylinder, hinge and frame details need to suit the intended door and local installation. Appearance alone does not establish compatibility.
For fire-rated or other tested assemblies, replacement or additional hardware must be checked against the applicable assembly documentation and project requirement.
Unknown measurements can be confirmed during the discussion. Use the enquiry form to describe the accessory type, intended use, approximate quantity and destination.
