Cylinder Lock Core MEGA 70 mm asymmetric brass insert model 24670

MEGA 24670 is a 70 mm asymmetric brass cylinder lock core designed for door locking systems that require an off-center keyway alignment. The insert features a solid brass body that offers resistance to corrosion and routine wear, making it suitable for residential and light commercial doors where a 70 mm cylinder length is needed. This asymmetric profile supports installations where the keyhole is not centered relative to the door thickness and integrates with compatible cylinder housings and mortise or rim locks.

Advantages

The brass construction of this 70 mm cylinder core ensures good corrosion resistance and long-term dimensional stability under normal use. Its asymmetric profile allows precise alignment for doors with off-center lock preparations, reducing installation adjustments. The insert is compatible with standard pin-tumbler mechanisms and can be replaced or upgraded without modifying the existing lock case when matching profile and size are observed.

Suitable for

• Residential external and internal doors requiring a 70 mm asymmetric cylinder
• Light commercial doors with off-center keyway alignment
• Replacement of worn or damaged cylinder cores in compatible locks
• Lock upgrades where corrosion-resistant brass components are preferred

Key specifications

• Material: Brass body for corrosion resistance
• Overall length: 70 mm (asymmetric configuration)
• Profile: Asymmetric cylinder suitable for off-center keyway positions
• Compatibility: Designed for standard cylinder housings and compatible pin-tumbler lock mechanisms

How to use

Ensure the existing lock case accepts a 70 mm asymmetric cylinder before installation. Remove the screw securing the old cylinder, align the new MEGA 70 mm asymmetric brass core so the cam engages the lock mechanism, and fasten it with the retaining screw. Verify smooth key operation and that the cam turns correctly to operate the latch or deadbolt. If necessary, check alignment and make minor adjustments to the lock case or strike plate to ensure proper engagement.

Usage recommendations

Regularly lubricate the keyway with a graphite-based or dry locksmith lubricant to maintain smooth operation and prevent buildup. For exterior doors, periodic inspection for corrosion or wear is advised; replace the cylinder if key operation becomes stiff or inconsistent. Confirm profile and length compatibility when ordering replacements to avoid fitment issues.
