Product and configuration identification

The official product name is “Flat Square Single Cylinder Mechanical Deadbolt”; the technical table currently identifies model 4881K19SQ. This record uses that configuration as its reference and does not mix in specifications from other versions in the series.

The table lists 9 specification or configuration facts. Original imperial values retain their units and are not rounded into installation dimensions.

Checks for replacement or selection

Compare photographs and the model of the existing equipment with the source document, then check the exact compatible model, version, interface and included accessories individually. Similar names or appearances do not establish direct interchangeability.

• Record the full model, colour or finish, function and document version.
• Record any inapplicable, missing or contradictory fields and confirm them with the manufacturer.
• Check fasteners, door requirements and installation orientation against the corresponding instructions.

Limitations

• Specifications are taken from the default model in the product page's technical table: 4881K19SQ. Recheck the model and specifications after changing the colour, function or package selection.
• The source product image is provided for identification only. Full installation instructions and marketing security ratings are not reproduced; product certification, connected-service availability, prices and stock have not been independently verified.
