Keep the strike, fixings, instructions and all compatible fittings with the new lockset. Missing components can prevent installation even when the main body is present. Do not assume unrelated spare screws or old fittings will meet the new product’s requirements.
The person arranging the job must have authority for the property and hardware change. For a rental or managed property, agree the appropriate permission and access contact. An enquiry does not establish ownership or authorise gaining entry to a locked property.
Hardware must suit the leaf thickness and the maker’s permitted range. Spindles and fixings are not interchangeable solely because the finish matches. Provide the door specification where possible and keep the complete supplied pack together until the fit is reviewed.
Replace suitable ordinary mechanical hardware in the compatible existing preparation and check its operation with the authorised customer. Scope limits: Authorised ordinary compatible mechanical lockset replacement only. No lockouts, emergency entry, key cutting, rekeying, locksmith security services, rated-door work or electrical integration.
