AMS Dual Lock Lever Handle – Aluminium Internal Handle with Turn Snib
The AMS Dual Lock Lever Handle Aluminium Internal Handle with Turn Snib is designed and developed exclusively for single-lever operation of dual-lock doors. One smooth downward action of the lever releases both locks simultaneously, eliminating the need for a double-handed unlocking sequence.
This model is the internal handle only variant of the AMS Dual Lock Lever Handle system. It incorporates the enhanced DLLH-33 T turn snib, allowing the upper deadbolt to be engaged or disengaged internally without affecting the single-action release of both locks.
External furniture is not included with this product. Where an external lever or cylinder plate is required, a paired handle set must be selected from the relevant AMS variants.
