Scope of use

• The HB2020 is intended for sliding doors (timber or aluminium) where a mortice-lock type locking mechanism is required. 
  • It is suitable as a stand-alone lock body, to be used in conjunction with separate handles or pulls — either flush-pulls or projecting pull handles. 
  • Designed for doors where a 55 mm backset is preferred or required (i.e., the lock case sits deeper into the door edge compared to narrower backset locks). 
  • Useful when two-prong locking claws (rather than a deadbolt) are desirable — suitable for sliding panels that overlap or meet, providing better engagement than a standard latch. 
  • Applicable in both residential and commercial projects, where durability (diecast zinc + brass construction) and reliability in a sliding-door context are required. 
  • Works well in installations where designers or fabricators want a recessed or minimal-profile locking solution, especially for flush-pull hardware configurations.
