HB640 250mm cylinder flush lock set

The Halliday+Baillie HB640 sliding door lock set series functions like the HB630 series, but with a narrow backset of 33mm and a lock body depth of 45mm. It is designed for use in aluminum or timber sliding doors with narrow stiles (50.8mm).

Sliding the snib on either side operates the bolt unless a cylinder is engaged. A cylinder will lock the snib; the key does not operate the bolt.

Suitable for timber or aluminium doors.

HB640 Narrow Backset Lock Body
2 Flush Pulls w/ HB604 Timber Fixing Kits
Strike and Dust Box
