Product FAQs

Frequently Asked Questions

What is the Britool Hallmark MREF250?

The MREF250 is a professional 3/8" drive extending ratchet featuring a telescopic handle, 180° locking flex-head, 72-tooth mechanism and safety socket release.

How long is the MREF250?

The handle extends from 246mm to 346mm, providing a total adjustment range of 100mm.

What is the advantage of an extending ratchet?

An extending ratchet allows you to shorten the handle when accessibility and control are important or increase its length when additional leverage or reach is required.

Does the flex-head lock?

Yes. The head pivots through 180° and locks securely into 10 different positions, allowing the user to select a suitable working angle.

How many teeth does the ratchet mechanism have?

The MREF250 features a 72-tooth fine ratchet mechanism.

What is the working arc?

The 72-tooth mechanism requires just 5° of handle movement between engagements, making it particularly useful in confined working areas.

Does it have a quick-release socket button?

Yes. The ratchet features a push-button safety socket release for secure socket retention and quick socket changes.

Is this also known as a telescopic ratchet?

Yes. Extending ratchet, extendable ratchet and telescopic ratchet are commonly used descriptions for this type of adjustable-length ratchet.

Is a 3/8" extending ratchet suitable for automotive work?

Yes. The 3/8" drive format is extremely versatile for automotive applications, while the adjustable handle and locking flex-head provide additional access and leverage when required.

Can I use the extended handle to loosen very tight fasteners?

Extending the handle provides additional leverage for tight fasteners. For heavily seized or exceptionally tight fasteners, however, a dedicated breaker bar or power bar should be used for the initial release to avoid unnecessarily loading the ratchet mechanism.

Why Choose the Britool Hallmark MREF250?

The Britool Hallmark MREF250 3/8" Drive Extending Ratchet provides the versatility of several ratchet styles in one professional tool.

Use it at 246mm when control and accessibility are the priority, or extend it to 346mm when additional reach and leverage are needed. The 180° flex-head with 10 locking positions then allows the handle angle to be adjusted around surrounding components.

Combined with its 72-tooth mechanism, fine 5° working arc and safety socket release, the MREF250 is an extremely versatile 3/8" drive ratchet for professional automotive, mechanical and workshop use.

Extending 246–346mm Telescopic Handle

The MREF250 features an adjustable handle that extends from 246mm to 346mm, giving the user the flexibility to alter the length of the ratchet according to the job.

At its shorter 246mm length, the ratchet provides improved manoeuvrability and control for general fastening applications.

When additional leverage or reach is required, the handle can be extended up to 346mm.

The additional handle length increases mechanical leverage, allowing greater turning force to be applied with less effort compared with using the ratchet in its fully retracted position.

180° Locking Flex-Head with 10 Positions

The ratchet head pivots through an impressive 180° range and can be securely locked into 10 different positions.

This allows the handle to be positioned at a more convenient angle when working around obstructions or accessing fasteners that cannot easily be reached with a conventional fixed-head ratchet.

The locking mechanism also provides greater control than a free-moving flex-head by holding the selected head angle securely during use.

This makes the MREF250 particularly useful when working around engine components, brake assemblies, suspension systems and other confined mechanical areas.

72-Tooth Fine Ratchet Mechanism

The 72-tooth ratchet mechanism requires just 5° of handle movement between engagements.

A small working arc is especially useful when space around the fastener is restricted, as the ratchet does not require a large handle swing before the next tooth engages.

Combined with the adjustable flex-head, the fine-tooth mechanism makes the MREF250 particularly effective for awkward and restricted fastener locations.

Push-Button Safety Socket Release

A convenient push-button safety socket release securely retains the socket on the 3/8" square drive during use.

When a different socket size is required, simply press the release button to quickly remove and replace the socket.

This combination of secure retention and fast socket changes is particularly useful during everyday professional servicing and repair work.

Versatile 3/8" Drive Format

The 3/8" square drive provides an excellent balance between the compact dimensions of a 1/4" drive tool and the higher-load capability of a larger 1/2" drive ratchet.

This makes the MREF250 particularly versatile for automotive servicing, where a wide range of medium-sized fasteners may need to be accessed in restricted locations.
