Model and scope of documentation

This record covers official model 5420D; the source is the manufacturer's US product page. Model suffixes form part of the product identity and must be retained when checking procurement or replacement documents.

The original page identifies the brand as Master Lock. This site's Chinese source organised the readable specifications into labelled fields; dimensions retain the manufacturer's original units and conversions without changing the measurement reference.

How to use these dimensions

The official technical fields for this model include: Shackle length 3/4 to 1-3/4 in (19 to 44 mm); Inside shackle width 1-13/32 in (36 mm); Shackle diameter 3/8 in (10 mm); External dimensions (height × width × depth) 4-5/8 in (117 mm) x () x 2 in (51 mm). These values identify this model and do not represent other products from the same brand.

External dimensions determine installation space; internal dimensions determine capacity for keys or other items. These are not interchangeable. Also check the opening direction and mounting surface.

Selection checklist

The following are documentation recommendations, not a manufacturer's compatibility guarantee. Matching specifications do not establish interchangeability in every application.

  • Check that the complete model 5420D matches the physical product or quotation.
  • Confirm installation space, mating holes and the clearance needed for opening and closing.
  • Separately confirm the supplied configuration, keying, operating environment and applicable local requirements.
  • For performance or certification conclusions, inspect evidence for the specific model rather than inferring from appearance or dimensions.

Limitations

  • This is model information from the official US catalogue, not a statement of local availability, stock or pricing in Central Asia.
  • Dimensions retain the original units; no physical testing or independent compatibility verification has been obtained.
  • Image links come from the official source page; image-use permission has not been verified. Confirm performance, warranty and certification on the original page.
