Invincible Euro Cylinder Multi Point Lock

The ERA Invincible euro cylinder multi-point lock is ERA's highest-performance multi-point locking system, engineered as a fully integrated security solution that pairs a purpose-built lock body with ERA's own British Standard 3-star Kitemarked Invincible cylinder.

The result is a premium, certified security package that delivers a level of protection well beyond what a standard euro cylinder multi-point lock can offer — making it the specification of choice for installers and manufacturers who refuse to compromise on door security.

Where a standard euro cylinder multi-point lock accepts any compatible euro profile cylinder, the Invincible system is designed differently.

The lock body and the Invincible cylinder are engineered to work together as a matched pair.

This dedicated pairing means the security performance of the combined system is optimised end-to-end — there are no compatibility uncertainties, no weak links introduced by mixing components from different manufacturers, and no risk of the cylinder being substituted with a lower-grade alternative down the line.

It's a closed, cohesive system built from the ground up to perform.

The Invincible cylinder at the heart of the system is British Standard 3-star Kitemarked and TS007 certified — independently tested and proven to resist the full range of modern attack methods, including cylinder snapping, picking, bumping and drilling.

Cylinder snapping in particular is one of the most common and most effective methods used by intruders to overcome euro cylinder locks.

The Invincible cylinder is specifically engineered to defeat this attack, with a design that maintains the integrity of the internal locking mechanism even under aggressive physical attack on the outer cylinder body.

Combined with the multi-point lock body — which drives multiple hardened hooks and rollers simultaneously into the door frame when engaged — the Invincible system provides a layered, certified security solution that is suitable for projects requiring PAS 24 compliance, Secured by Design accreditation and other enhanced security specifications.

ERA's Invincible multi-point lock range is available across three configurations: hook and roller locks for PVCu doors, hook locks for timber and composite doors, and passive locks for use on double door configurations across all door materials.

Whether you're installing a PVCu entrance door on a new build development, fitting a composite door on a high-specification residential renovation or completing a commercial installation where certified security performance is a requirement, the Invincible range has the right product for the application.

For door manufacturers building to a consistently high security specification across a range, the Invincible system also offers a clear and credible marketing benefit — the ability to specify a British Standard 3-star certified, integrated locking system as standard, supporting stronger sales conversations with end clients and developers who are increasingly aware of and attentive to door security standards.

Frequently Asked Questions

What is the ERA Invincible euro cylinder multi-point lock?

The ERA Invincible euro cylinder multi-point lock is a premium, integrated door locking system that combines a purpose-built multi-point lock body with ERA's own British Standard 3-star Kitemarked Invincible cylinder.

Unlike standard euro cylinder multi-point locks — which accept any compatible euro profile cylinder — the Invincible system is designed as a matched pairing of lock and cylinder, with both components engineered to work together for optimised, certified security performance.

The system is available in hook and roller configurations for PVCu doors, hook-only configurations for timber and composite doors, and passive lock versions for double door applications.

What makes the Invincible system different from a standard euro cylinder multi-point lock?

The key difference is the integration between the lock body and the cylinder. A standard euro cylinder multi-point lock is an open system — it will accept any euro profile cylinder, which means the security of the overall installation depends entirely on the quality of whichever cylinder is fitted, and there is no guarantee that a high-grade cylinder will be maintained throughout the door's life.

The Invincible system is a closed, matched pairing — the lock is designed specifically to work with the Invincible cylinder, and the Invincible cylinder is designed specifically for use with the Invincible lock.

This end-to-end engineering approach eliminates the compatibility uncertainty of open systems and ensures the security performance of the combined system is certified and consistent.

What security certifications does the Invincible system hold?

The ERA Invincible cylinder is British Standard 3-star Kitemarked and independently tested to the TS007 standard.

TS007 3-star certification means the cylinder has been rigorously assessed for resistance to the most common and most aggressive forced entry techniques — specifically cylinder snapping, picking, bumping and drilling.

When the Invincible cylinder is paired with ERA's Invincible multi-point lock body, the combined system provides a security solution suitable for PAS 24 compliant installations, Secured by Design accreditation and other enhanced security specifications.

What is cylinder snapping and how does the Invincible cylinder protect against it?

Cylinder snapping is a method of forced entry where an intruder uses leverage to physically snap the exposed outer portion of a euro profile cylinder, exposing the internal mechanism and allowing the door to be opened without a key.

It is one of the most commonly used techniques by burglars targeting modern entrance doors fitted with standard euro cylinder locks.

The ERA Invincible cylinder is specifically engineered to resist this attack.

Its internal construction is designed so that even if the outer portion of the cylinder is subjected to significant force, the internal locking mechanism remains intact and the door stays secure — providing a critical layer of protection that standard cylinders do not offer.

Is the Invincible multi-point lock suitable for PAS 24 compliant installations?

Yes. ERA's Invincible euro cylinder multi-point lock, when specified as part of a complete hardware package with appropriate hinges, is suitable for use in PAS 24 compliant entrance door installations.

PAS 24 is the enhanced security performance standard required for new build residential properties under Part Q of the Building Regulations in England, and is also widely specified on social housing, housing association and commercial projects.

The Invincible system's British Standard 3-star cylinder and multi-point hook locking mechanism make it a strong foundation for PAS 24 compliant door sets.

What door types is the Invincible multi-point lock available for?

ERA's Invincible euro cylinder multi-point lock range covers all the major entrance door types encountered in the UK market.

Hook and roller lock configurations are available for PVCu doors, where the rollers provide compression against the weatherseal as well as a secure locking engagement. Hook lock configurations are available for timber and composite doors, where the frame geometry and sealing requirements call for a hook-only mechanism.

Passive lock versions are available for all door materials, for use in double door installations where a second lock body is required to extend locking coverage across the full height of the door.

What is a passive Invincible lock and when is it used?

A passive Invincible lock is a secondary lock unit used in conjunction with an active Invincible multi-point lock on double door configurations.

It is mechanically linked to the primary lock and operates automatically when the main handle is engaged, without requiring a separate handle or cylinder.

Passive locks allow the full height of a double door installation to be secured with multiple locking points on both the active and passive door leaves, without complicating the operation for the end user. ERA's passive Invincible locks are available for PVCu, timber and composite door applications.

Can the Invincible lock be used with any handle?

ERA's Invincible multi-point lock is compatible with ERA's range of standard handles for the Invincible cylinder multi-point lock system, which includes a selection of styles and finishes designed specifically for use with this lock.

Because the Invincible system uses a dedicated cylinder format that differs from a standard euro profile cylinder, it is important to specify handles from ERA's Invincible-compatible handle range rather than standard euro cylinder handle sets.

This ensures that the handle, cylinder and lock body all operate together correctly and the full security performance of the system is maintained.

Why should trade installers and door manufacturers specify the ERA Invincible system?

The Invincible system offers a demonstrably higher level of door security than a standard euro cylinder multi-point lock, backed by British Standard 3-star certification and TS007 independent testing.

For trade installers, specifying an Invincible system means delivering a product that clients can trust and that meets or exceeds the requirements of enhanced security standards including PAS 24 and Secured by Design.

For door manufacturers, building with the Invincible system as standard provides a clear, certifiable quality and security differentiator that supports stronger commercial positioning in a competitive market.

ERA's reputation and technical support further underpin the Invincible range as a specification choice that installers and manufacturers can stand behind with confidence.
