Dropbolts / DF

A range of keyed and non-keyed flush-mounting dropbolts with round styled and 20mm throw Designed for use with sliding and bifolding doors. Centor's DF will resist high winds and is rated to resist a 250kg load in Western Red Cedar and 450kg in Amoora.

Centor can test your actual door section and provide a test certificate stating the rating achieved. DF 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, bright gold, bright chrome, brushed satin and custom powdercoat finishes. The bolts are available keyed alike and may be rekeyed by a professional locksmith.
