Window Handles with Locks: Espag vs Cockspur Options

Window handles with locks are an important choice for both security and everyday convenience. Homeowners want reliable locking that integrates with their windows, while tradespeople need products that are simple to fit, durable and compliant with current standards. This article compares espagnolette (espag) and cockspur handles, explains when each is appropriate and gives practical guidance on selection, installation and maintenance.

Espag vs cockspur — basic differences

Espagnolette (espag) handles operate a multipoint locking mechanism via an internal spindle and gearbox that turns a steel espag bolt into the frame. They are common on modern uPVC and aluminium casement windows. Cockspur handles sit on the face of the frame and engage a latch or spur that hooks over the frame; they are widely used on older windows and some timber frames.

Key contrasts:

• Security: Espag systems usually provide higher security because the locking rod engages multiple points along the sash. Cockspur locks are generally single-point and less resistant to forced entry unless augmented with additional locks.
• Suitability: Espag handles suit rebated frames and windows designed for espag locking. Cockspur is useful where retrofitting to an existing frame is required and where the frame does not accommodate espag hardware.
• Appearance and operation: Espags sit flush with the handle recess and operate by turning; cockspurs protrude and operate by lifting or turning the handle to engage the spur.

Choosing the right type for the property

Selection depends on window type, security needs and whether the installation is new or a replacement. For new builds or full window replacement, specifying espag locking is generally preferable for improved security and weather sealing. For older properties where sill and frame profiles prevent an espag rod fitting, a cockspur handle is often the practical option.

For properties requiring enhanced security or where insurance stipulates multipoint locking, choose espag handles with robust locking features. A quality espag handle such as the TSS Cockspur Window Handles offers secure engagement and is designed for modern multipoint gearboxes.

Locking types and features to consider

Window handles with locks come in several locking methods. Understanding them ensures an appropriate choice.

• Keyed handles: Provide a key lock on the handle spindle for added security. Ideal for ground-floor windows or vulnerable locations. The key should be left in a secure spot during occupation.
• Push-button locks: Simple to operate and good for internal rooms where high security is not required.
• Deadlocking latch: On cockspur handles, consider versions with a deadlocking feature to resist forced lifting of the spur.
• Lockable espag gearboxes: Some espag handles feature positive locking that prevents the handle being forced if the gearbox is not engaged.

The TSS Offset UPVC Window Handles is an example of a reliable keyed or non-keyed option that balances cost and performance for many residential applications.

Practical fitting and measurement tips for tradespeople

Accurate measurement and correct spindle length make the difference between a quick fit and multiple site visits.

• Measure backset and spindle length: For espag handles, check the spindle length and backset measurement (distance from handle centre to outer edge). Most manufacturers specify common sizes; keep a selection of spindles on the van.
• Check screw positions and the centre-to-centre fixing distance for cockspur handles so the new handle aligns with existing holes.
• Confirm handing: Determine whether the handle is for a left- or right-hand opening sash. Many handles are reversible but confirm before fitting.
• Keep spares for common fault types: Replacement gearbox and spindle sets resolve many failures without sash removal.
• When retrofitting espag to a non-espag frame, assess frame depth and rebate — cutting or major modification is often costly and may risk weatherproofing.

Tradespeople should follow manufacturer torque limits when tightening fixings to avoid stripping threads or deforming the handle.

Security and compliance considerations

Security specifications may affect product choice. Where possible choose handles and gearboxes that contribute to compliance with standards such as PAS 24 or Secured by Design recommendations. Multipoint espag systems generally meet higher performance levels. For vulnerable ground-floor openings, specify keyed locks or additional secondary locks.

Insurance providers sometimes require specific locking arrangements; document the chosen hardware and its security credentials for warranty and claims purposes.

Maintenance and troubleshooting

Regular maintenance keeps window handles with locks functioning and prevents premature failure.

• Lubricate moving parts annually with a light machine oil or silicone spray; avoid heavy grease that attracts dirt.
• Tighten fixings and check spindle for wear during scheduled maintenance visits.
• For stiff operation, check the sash alignment and hinges before replacing handles; misalignment often causes handle stress and failure.
• Replace worn espag rods rather than multiple small repairs where corrosion or bending is evident.

For cockspur installations, ensure the spur makes full contact with the keep and that weather seals are intact to prevent drafts and water ingress.

Recommended use cases

• Espag handles: Best for modern uPVC and aluminium windows, high-security requirements and where multipoint locking is fitted.
• Cockspur handles: Suitable for older timber or metal frames where minimal modification is required, and for cost-effective replacements on upper-floor windows where high security is less critical. The TSS Cockspur Window Handle is a dependable option for retrofit scenarios.

Final selection checklist

Before purchasing, confirm:

• Window type and frame depth
• Required security level (keyed vs non-keyed)
• Spindle length and backset
• Handing and fixing hole positions
• Compliance or insurance requirements

Choosing the correct window handles with locks ensures both security and longevity of the installation. Proper measurement, selection of appropriate locking type and regular maintenance will reduce call-backs and contribute to satisfied homeowners.
