Sorrento Mortice Lock and Handle for Aluminium Doors
Lidco is pleased to announce the introduction of the new Sorrento mortice lock and handle for use with the Lifestyle Hinged Door (150 System) and Lifestyle Bifold Door (615 System). This reliable new lock set has a beveled latch bolt that is extended further into the strike plate when locked by key or snib.
