Centurion Silver Cylinder Lock, 70mm Euro Profile, 5-Pin

70mm Euro Profile Cylinder

The Centurion Silver Cylinder Lock provides a standard security solution for residential and commercial timber or aluminum doors. This 70mm double-entry component allows for key operation from both sides of the leaf. It serves as a direct replacement for worn or compromised barrels in existing mortice lock sets requiring a Euro-spec profile.

Built for the Job

This hardware is designed for high-traffic environments where consistent mechanical reliability is mandatory. The 35/35mm equal offset ensures a centered fit in standard 40mm to 50mm door thicknesses when accounting for handle backplates or escutcheons. Contractors frequently utilize this specific size for retrofitting projects because it aligns with the most common door widths found on modern job sites. The internal cam mechanism uses high-strength alloys to prevent binding during heavy daily cycles.

• Installation in external timber entrance doors using standard mortice lock bodies.

• Replacement of damaged cylinders in commercial aluminum storefront partitions.

• Key-alike upgrades for facility managers overseeing multiple office entry points.

Product Highlights

Security Architecture

The 5-pin tumbler system incorporates anti-pick drivers to increase resistance against common unauthorized entry techniques.

Material Composition

• Brass internal core prevents internal corrosion and ensures smooth key rotation.
• Satin silver plating provides a durable finish that resists oxidation in humid environments.

Technical Specifications

What’s Included

• 1 x 70mm Euro Profile Cylinder

• 3 x Nickel-Plated Steel Keys

• 1 x M5 Retaining Bolt (65mm)

On-Site & Workshop Notes

• Always measure from the center of the fixing hole to the outer edge of the cylinder to verify the 35mm offset before drilling.

• Use dry graphite lubricant for maintenance; avoid using oil-based sprays which attract dust and cause mechanical sticking.

• Ensure the cam is set at a 30-degree angle during insertion to clear the lock body internals without forcing the unit.

• Do not over-tighten the lateral retaining screw as this can lead to operational friction or cylinder misalignment.
