Adjustable Tension for Rigging, Bracing & Trade Installations

Need to take up slack, fine-tune a connection or bring a tensioned assembly into position? Securefix turnbuckles provide an adjustable hardware solution for suitable rigging, bracing, cable, fabrication & general trade installations where controlled adjustment matters.

Built around a commercial galvanised range, Securefix turnbuckles are available in Stub/Stub, Hook/Eye & Eye/Eye configurations, with sizes across M12, M16, M20, M24 & M30. Different end styles make it easier to choose around the connection already planned rather than forcing one turnbuckle configuration into every job.

Selecting a turnbuckle takes more thought than matching a thread diameter. Connection style, system geometry, compatible hardware, required adjustment, environmental exposure & the demands of the complete assembly should all be considered before installation.

► Commercial galvanised construction
► Stub/Stub, Hook/Eye & Eye/Eye configurations
► M12, M16, M20, M24 & M30 sizes across the range
► Adjustable hardware for suitable tensioning applications
► Options for construction, fabrication, maintenance & general trade work

What Are Securefix Turnbuckles?

A few turns of the body can make the difference between unwanted slack & a properly adjusted connection. Turnbuckles are adjustable hardware components used to increase or decrease tension between suitable connected components without repeatedly dismantling the complete assembly.

At the centre of the component sits an adjustable body with threaded connections. Rotating the body changes the effective length of the assembly, providing a practical way to fine-tune tension or positioning within the limits of the particular turnbuckle.

Securefix offers several end configurations because connection points vary from job to job. The range includes Stub/Stub, Hook/Eye & Eye/Eye turnbuckles, allowing buyers to start with the hardware arrangement their installation actually requires.

Think of the turnbuckle as the adjustable link in a larger chain of components. Every attachment point, connector, cable, fastener & supporting component still needs to be compatible with the complete setup.

Why Choose Securefix Turnbuckles?

Fixed hardware holds a connection in place. A turnbuckle gives that connection room for controlled adjustment. That distinction becomes valuable when slack needs to be removed, tension refined or positioning corrected after the main attachment points have been established.

Imagine a suitable cable or bracing assembly that's almost where it needs to be but requires a final adjustment. Rebuilding the connection every time the effective length changes would be cumbersome, whereas an appropriately selected turnbuckle creates an adjustable point within the system.

Stub/Stub Turnbuckles

Working with an assembly designed around threaded stub connections? A Stub/Stub turnbuckle provides that configuration at both ends.

Securefix Stub/Stub options are available across multiple sizes, giving buyers choices for assemblies built around different thread requirements.

Hook/Eye Turnbuckles

Different connection points at opposite ends call for a different approach. Hook/Eye turnbuckles combine an open hook-style connection at one end with an eye at the other.

That arrangement can suit applications specifically designed around those two connection styles while retaining adjustment through the turnbuckle body.

Eye/Eye Turnbuckles

Closed connection points on both sides can make an Eye/Eye configuration the logical starting point. An eye at each end provides a different connection arrangement from Hook/Eye or Stub/Stub designs.

End style shouldn't be chosen from appearance alone. Start with the actual connection points then select the configuration intended to work with them.

Common Applications

Where does adjustable tension make the biggest difference? Turnbuckles can appear across a wide variety of suitable trade installations, but the hardware needs to be chosen around the requirements of the complete system.

Bracing & Construction

A connection that needs fine adjustment may benefit from having a turnbuckle incorporated into the intended bracing arrangement.

Engineered & structural applications require particular care. Follow the project specification & use components with the required performance information rather than assuming a commercial turnbuckle is suitable because its dimensions appear substantial.

Cable & Wire Assemblies

Slack can develop or need adjustment as cable-based assemblies are positioned.

A suitable turnbuckle creates an adjustable point within the arrangement, while the cable, connectors, anchor points & associated hardware still need to function as a compatible system.

Fabrication & Workshop Setups

Fabrication work sometimes requires components to be positioned, adjusted or held within a suitable tensioned arrangement.

An appropriately selected turnbuckle can provide useful adjustment without requiring the connection to be repeatedly rebuilt.

Equipment & Maintenance

Replacing worn hardware isn't simply a matter of finding something with a similar overall length.

Where a turnbuckle forms part of an existing system, check its thread size, end configuration, surrounding components & intended adjustment before selecting the replacement.

General Trade Installations

Workshop projects, equipment installations & suitable property or site applications can all present situations where an adjustable connection is useful.

Before adapting a turnbuckle to a new purpose, confirm that the component & every attachment around it are appropriate for the intended application.

Product Selection Guide

Start at the attachment points & work towards the middle. Once you know how each end needs to connect, choosing the turnbuckle becomes considerably more straightforward.

Choose the End Configuration

First ask what needs to happen at both ends of the assembly.

Stub/Stub provides threaded stub-style ends for connections designed around that arrangement.

Hook/Eye combines an open hook at one end with an eye connection at the other.

Eye/Eye provides eye-style connections at both ends.

Don't substitute configurations simply because two products share the same nominal thread size.

Match the Thread Size

Securefix turnbuckles in this range cover M12, M16, M20, M24 & M30 sizes across the available configurations.

Thread diameter is important for compatibility, but it isn't a shortcut for determining the suitability of the complete assembly.

Where loading matters, check the individual product information & requirements of the intended system.

Allow Useful Adjustment

A turnbuckle already sitting at the end of its adjustment has little left to offer.

Consider the distance between the connection points before installation & think about whether the assembly may need to be tightened or relaxed later.

Planning usable adjustment into the setup gives the component room to perform the job it was selected for.

Consider the Environment

The Securefix products in this collection are identified as galvanised, but the working environment still deserves attention.

Moisture, contaminants, chemicals, coastal exposure & contact with other materials can influence hardware over time.

Choose around the actual conditions rather than assuming one finish suits every exposed application.

Check Every Connected Component

A turnbuckle doesn't work alone.

Before installation, review:

► Attachment points
► Cable, chain or connected material
► Connectors & links
► Thread compatibility
► Connection geometry
► Required adjustment
► Environmental exposure
► Applicable project or load requirements

Expert Tips

Adjustment is the turnbuckle's advantage, but only when the installation leaves room to use it. A few checks before tensioning can make future adjustment & inspection considerably easier.

Leave Adjustment in Reserve

Starting at one extreme of the available movement can limit what happens next.

Set the assembly with enough usable adjustment remaining for the intended application rather than winding the component to its limit before the job has even begun.

Look Past the Turnbuckle

The most substantial component in the assembly can't compensate for a poor attachment point.

Inspect what's connected at both ends. Hardware, anchors, cable, chain & supporting components should all be suitable for the intended setup.

If a connector or attachment point shows damage, distortion or questionable engagement, investigate it before adding tension.

Keep the Connection in Line

An awkward angle can change how forces travel through an assembly.

Stand back & look at the complete connection before making the final adjustment. The turnbuckle should sit in a sensible relationship with the components attached to it rather than being forced into an unintended position.

Don't Judge Capacity by Appearance

An M30 turnbuckle naturally looks more substantial than an M12, but visual size alone doesn't establish what a component is rated to do.

Critical, structural, load-restraint or lifting-related applications require appropriately specified equipment selected for that particular purpose.

For jobs involving dedicated lifting equipment, browse Lifts & Hoists rather than treating a general-purpose turnbuckle as lifting hardware.

Inspect Before Reuse

Hardware that's already completed one job deserves another look before starting the next.

Check for:

► Damaged or difficult threads
► Distortion
► Significant corrosion
► Cracks or visible damage
► Worn connection points
► Abnormal movement
► Evidence of misuse

A component that no longer adjusts normally shouldn't simply be forced back into service.

Use a Tool That Fits

A poorly fitting tool can damage hardware before the adjustment is even complete.

Select a suitable wrench or spanner for the surrounding threaded hardware rather than improvising with a tool that only partly engages.

Browse Wrenches for hand tools suited to adjustment & fastening work.
