Geepas 70mm Double Cylinder Mortise Lock, Comes with Double Brass Cylinder & 3 Keys

Key features include double brass cylinders for enhanced security, three keys included, an anti-theft fixing screw to deter tampering, an adjustable latch to fit varying door thicknesses, a glossy finish for aesthetics, and easy operation for routine use.

The package typically includes the Geepas mortise lock body, 3 keys, mounting screws, strike plate, and an anti-theft fixing screw. Some bundles may also include installation screws or a template for alignment.

This lock is designed for standard entry/ exterior-type doors that accept a mortise lock with adjustable latch. The latch is adjustable to accommodate thicker door leaves, making it compatible with a range of common door thicknesses. It is ideal for doors where both sides need key access for security.

Installation steps typically include: 1) verify door suitability and measure thickness. 2) mark and chisel out the mortise pocket if required. 3) align and insert the lock body, ensuring the spindle and cylinders align with handles/keys. 4) drill holes for the handle/knob and latch, fit the strike plate, and secure with screws, including the anti-theft fixing screw. 5) test locking/unlocking from both sides and adjust the latch as needed for smooth operation.

Keep the lock clean and dry. Lubricate moving parts with a light graphite-based or silicone lubricant occasionally, especially if you notice stiffness or sticking. Avoid harsh liquids that could corrode brass cylinders. Regularly check screw tightness and alignment to prevent misoperation.

Double-cylinder locks require keys to operate from both sides, offering higher security for doors that open to untrusted spaces (like street-facing doors or ground-floor entrances). Single-cylinder locks use a key on one side and a thumb-turn on the other, which is convenient but potentially less secure in some scenarios. This Geepas model provides robust security with two key-access points and the added benefit of three keys.

Use cases include securing entry doors at homes or offices, doors that require dual-side access control, and situations where tamper resistance is important. Its sturdy construction and double cylinder design make it suitable for exterior doors or internal doors that require higher security.
