Glass sliding door lock challenges
Slim frame limitations
Glass door frames (especially aluminium) are much narrower than UPVC frames. Standard locks simply won't fit. Specialist slimline profiles are required.
Seal and alignment issues
Glass doors rely on perfect alignment for both operation and weather sealing. Lock replacement often requires re-alignment of the entire door system.
Premium system complexity
High-end systems (Schuco, Origin, Reynaers) use proprietary locking mechanisms. Only experienced specialists should attempt replacement.
Commercial grade requirements
Commercial glass doors often need master key systems, access control integration, and insurance-compliant security ratings.
