Measuring Instructions – Selecting the Correct Pin Height:

Before Installation:

Determine the clearance depth between your closed window sash and the window frame. This measurement identifies which striker post height will provide optimal installation:

• 9.5mm Striker Post: Suited for shallow frame profiles with limited clearance depth
• 11.5mm Striker Post: Designed for standard uPVC window frames (most typical installation)
• 14.5mm Striker Post: Appropriate for deeper frame profiles with increased clearance depth

Measurement Technique:

• Close your window sash completely
• Identify the friction stay hinge groove (the channel housing your existing window hinge mechanism)
• Measure the depth from the groove base to the window sash edge
• Choose the striker post height that will sit slightly below the sash surface when installed

⚠ Critical Note: The striker post must remain slightly recessed – any protrusion above the window sash surface will prevent proper window closure and may damage the restrictor mechanism.

Pro Tips:

Pro Tip: Take advantage of having all three pin heights included by test-fitting each option before final installation. Start with the middle 11.5mm height for most standard uPVC frames, then adjust up or down if needed. When installing across multiple windows, maintain consistent restrictor positioning by measuring from the hinge point to ensure uniform appearance and operation throughout your home. Always test the 100mm restriction measurement before final tightening – the window should halt firmly at the safety distance without requiring excessive closing force.

Frequently Asked Questions:

Will this restrictor fit my tilt and turn windows?
This restrictor is engineered specifically for side-opening casement windows and top-hung windows fitted to uPVC frames. It's not compatible with tilt and turn mechanisms, sliding sash configurations, or bottom-hung opening styles. If your windows feature casement operation (opening outwards or inwards on side hinges) or top-hung operation (opening outwards from the top edge), this restrictor delivers excellent child safety protection.

Can I access the full window opening for exterior cleaning?
Absolutely. The spring-actuated arm disengages manually whenever you require complete window access for external glass cleaning, maintenance activities, or emergency egress situations. Simply release the arm from its engaged position to achieve full window opening. The autolatch mechanism re-engages automatically when you close and subsequently reopen the window – no manual resetting required.

Does this restrictor meet insurance requirements for child safety?
This restrictor limits window opening to 100mm, which corresponds with recommended child safety standards for upper-floor windows. However, insurance requirements differ between providers and property classifications. We advise reviewing your policy documentation or consulting your insurance provider directly to verify compliance with their specific requirements.

How does stainless steel perform in humid environments?
Genuine stainless steel construction delivers superior corrosion resistance, even when exposed to humid bathroom or kitchen conditions. The material preserves its structural performance and visual appearance throughout years of continuous use, making this restrictor a dependable long-term investment in family safety rather than a short-term solution requiring regular replacement.

Why are three pin heights included instead of choosing one?
Including all three striker post heights eliminates measurement uncertainty and guarantees you have the correct option for your specific window profile. This comprehensive approach means you can test-fit each height during installation to achieve perfect alignment, and you'll have spare options available if you need to install additional restrictors on windows with different frame depths elsewhere in your home.
