  • Harmony Dropbolt

    A range of keyed and non-keyed flush-mounting dropbolts with square styling and 40mm throw designed for use with sliding and bifolding doors, Harmony will resist high winds and is rated to resist a 250kg load in Western Red Cedar and 450kg in Amoora. Centor Architectural can test your actual door section and provide a test certificate stating the rating achieved. Harmony features a unique damage-proof mechanism for bifold doors which prevents the bolt being operated if the key is left in the lock. The bolts are easily installed with a dedicated router bit and are available in Satin Natural and Bright Gold finishes. The bolts are available keyed alike and may be rekeyed by a professional locksmith.
