HB1830 Key Locking Flush Bolt (Round Throw)

The HB1830 is designed for applications where a secure, key-operated flush bolt is required for large or heavy doors. Suitable for:

• Timber, aluminium, and steel doors where a concealed locking solution is preferred
• Sliding, pivot, and hinged doors needing additional security through a keyed flush bolt
• Large-scale doors requiring a robust bolt body (minimum door thickness: 45 mm timber, 35 mm aluminium)
• Architectural and high-spec residential or commercial projects where aesthetic integration and performance are important
• Situations requiring a round-throw bolt for alignment with receivers in head, jamb, or sill
• Installations needing a Euro cylinder key system, allowing the bolt to be key-operated from one side

Please note that these bolts are not designed to be used as both handle and bolt and we recommend using with an additional flush pull (please see the HB660, HB665, or HB668 for matching width options).

Ships with fixing kits, strike plate and includes a standard 3pin Euro cylinder that sits flush with the face of the bolt (21mm from centre of cam to edge). Available in round bolt end only. Extension kits available separately.

Note : please check dimension drawing for suitability with your track system.
