HB640 Series Narrow Sliding Door Lock – 33mm Backset

Halliday + Baillie Key Lock Sliding System with 33mm backset and a case depth of 48mm.

The slim proportions of the HB640 Series lock sets make them ideal for narrow style timber and aluminium joinery. The HB649 vairiants are particularly useful on sliding windows that require locking. Cylinders can be ordered separately with confirmation of the door thickness.

Please note that the “HB640 Series” denotes the type of lock body used with various flush pull configurations. The “HB640” set has a key and snib both sides, and is one possible configuration in the series.

Material: Diecast zinc with brass and 316 stainless steel

Backset : 33mm

Minimum door thickness : 38mm

Flush pulls : 250mm x 36mm x 13mm

Suitable for timber or aluminium doors with narrow stiles

PLEASE NOTE: In the HB648 and HB649 configurations the lock and flush pulls will be offset slightly along the height of the door and not line up with the top and bottom of the flush pulls.

For finish options please see our current Finishes Sheet. Please check with your local Halliday + Baillie representative as not all finishes are available in all regions.

Flush pulls are designed to be mounted with the body within the thickness of the door, and the face plate on the door surface – total projection is 2mm. Fully recessed mounting is possible on timber doors with the appropriate door thickness. Using glue, epoxy or silicone products etc to secure flush pulls to the door is not required or recommended for installation, and may void warrantee. Glue, epoxy, or silicone products can be used to secure the spindle bar to the back of the snib flush pull for example where sets have a flush pull to one side only.
