Nico Inline uPVC Window Espag Rod Lock Mechanism

Nico Inline uPVC Window Espagnolette Rod Lock Mechanism – Multi-Point Locking System

Secure your windows with proven multi-point locking technology and adjustable weatherseal compression.

Nico Inline Espagnolette Rod Lock Mechanism provides reliable multi-point locking security for uPVC casement windows. This genuine Nico espag rod delivers robust performance with eccentric mushroom cams that offer +/- 1mm weatherseal adjustment, ensuring optimal compression and draught-proofing throughout the year. Engineered for longevity and tested over 30,000 duty cycles in Nico's dedicated test centre, this espagnolette mechanism represents proven quality for window security and performance.

Available in seven different lengths from 170mm to 1150mm, the Nico Espagnolette accommodates various window sizes with configurations ranging from one to three cams and two to six fixing holes depending on length. Designed to work with existing keeps on most major uPVC profiles, this is a versatile replacement solution for failed or worn espag mechanisms when your window frame keeps remain serviceable.

Key Benefits:

• Multi-Point Locking Security – Engages multiple locking points simultaneously along the window frame, significantly enhancing security compared to single-point locks and providing insurance-compliant protection for your home.
• Adjustable Weatherseal Compression – Eccentric mushroom cams with +/- 1mm adjustment capability allow precise weatherseal compression tuning, eliminating draughts and reducing heating costs while extending seal longevity.
• Proven Durability Testing – Every Nico Espagnolette undergoes rigorous 30,000 duty cycle testing in the manufacturer's own test centre, ensuring reliable performance that outlasts generic alternatives and reduces future replacement costs.
• Works with Existing Frame Keeps – Designed to operate with keeps already installed in most major uPVC window profiles, allowing cost-effective espag rod replacement without needing to replace serviceable frame keeps or modify your existing window hardware.
• Comprehensive Size Range – Seven available lengths (170mm to 1150mm) ensure precise dimensional matching for virtually any casement window configuration, with cam and fixing hole quantities optimised for each size.
• Enhanced Sash Compression – Longer sizes (950mm and 1150mm) feature an additional central cam for improved compression on larger window sashes, maintaining consistent weatherproofing across the entire frame perimeter.
• Genuine Nico Quality – Authentic Nico manufacturing guarantees precision tolerances, corrosion-resistant materials, and engineering standards that generic espag rods simply cannot match, protecting your investment long-term.
• Standard Drive Compatibility – 7mm square spindle drive and 43mm handle fixing centres ensure compatibility with the vast majority of uPVC window handles, simplifying replacement without requiring additional components.

Important: Accurate measurement of your existing espagnolette length and backset is essential for correct fitment. Measure the total length of the espag rod from end to end, and verify the backset (distance from the espag rod faceplate to the centre of the handle spindle hole).

Pro Tips:

Pro Tip: When replacing an espagnolette rod, take the opportunity to adjust the eccentric mushroom cams for optimal weatherseal compression. Turn each cam slightly using an allen key (hex key) to achieve the perfect balance between smooth operation and tight seal compression. If your window feels stiff to close, reduce compression slightly; if you notice draughts, increase compression gradually until eliminated.

Frequently Asked Questions:

How do I determine which length espagnolette I need for my window?
Measure your existing espag rod from end to end – this is your required length. If you're unsure, remove the window handle and carefully extract the existing espag rod to measure it directly. The length measurement is critical for proper operation, as an incorrect length will prevent the locking mechanism from engaging all keeps correctly, compromising both security and weatherproofing.

What's the difference between 20mm and 22mm backset, and which do I need?
The backset is the distance from the espag rod faceplate to the centre of the handle spindle hole where your handle attaches. Measure this distance on your existing espag rod or window frame. Using the wrong backset will cause misalignment between the handle spindle and the espag mechanism, preventing proper operation. The 2mm difference is significant in window hardware – always match your existing backset exactly.

Can I adjust the Nico espagnolette if my window is too stiff or has draughts?
Yes – this is precisely what the eccentric mushroom cams are designed for. Each cam can be rotated to adjust weatherseal compression by +/- 1mm, allowing you to fine-tune the balance between secure sealing and smooth operation. If your window feels excessively stiff when closing, reduce compression by rotating cams slightly counterclockwise. If draughts are present, increase compression by rotating cams clockwise until the seal is tight but the window still operates smoothly.

Will this Nico espagnolette work with my existing window handles and keeps?
The Nico espagnolette uses industry-standard dimensions: 7mm square spindle drive and 43mm handle fixing centres, ensuring compatibility with the vast majority of uPVC window handles. This espag rod is designed to work with your existing window frame keeps – the metal receivers mounted in the frame that the mushroom cams engage with. Please note that keeps are not included with this espag rod; you'll be reusing your existing frame keeps. Verify your existing handle uses a 7mm square spindle – this is the most common size but some older windows may differ.

Are the window frame keeps included with this espag rod?
No, this product supplies the inline espagnolette rod mechanism only. The window frame keeps (the metal strike plates mounted in the window frame that the mushroom cams lock into) are not included. In most espag rod replacement scenarios, the existing frame keeps remain serviceable and only the espag rod itself requires replacement due to internal mechanism wear. If your frame keeps are also damaged or missing, these would need to be purchased separately.
