4905/70SC Internal Square End Plate With 70 Lever - Satin Chrome

The Lockwood 4905/70SC Internal Square End Plate with 70 Lever is a premium, commercial-grade narrow-stile door furniture accessory manufactured by ASSA ABLOY / Lockwood. It is specifically optimised for narrow aluminium stile doors where a clean visual profile without a key cylinder or turn snib is required. The plate measures 185mm high x 26mm wide x 11.5mm thick, paired with a robust, ergonomic 70 series tubular lever that projects 53mm, with a total handle length of 121mm. Fixing uses 160mm screw hole centres with a visible physical tie-bolt configuration, and the plate is designed to fit back-to-back across standard residential or commercial aluminium doors ranging from 32mm to 50mm thick. It is machined from high-quality solid brass block substrates and finished in an anti-corrosive Satin Chrome treatment. The 70 series return-to-door tubular handle is fully compliant with Australian Disabled Access Standards (AS1428.1-2009), ensuring safe operational clearance margins for public and institutional facilities. It is also officially certified to an S3 Security and D3 Durability rating under AS4145.2, and is fully approved and fire-rated for use across commercial smoke and fire containment paths. The internal design is non-handed, with the symmetrical lever able to be flipped or reversed on-site by backing out an internal stop screw assembly. This internal faceplate is designed to operate back-to-back with external plates, such as the concealed-fix Lockwood 4800 series, acting as the mechanical lever control linkage for premium short-backset locks including the Lockwood 3580/3780 Series Mortice Locks and Latches, and Lockwood 3540 narrow-stile commercial sliding or deadbolt paths.
