Window Lock

Description

Mr.Goodbar Security – Keyed window restrictors are locking devices that limit how far a window can open to help prevent falls, improve security, and meet safety regulations. Unlike keyless models, they require a key to unlock and allow full opening, which adds a layer of security and prevents accidental or unauthorized release.

They’re commonly used for:

• Child safety (upper-floor windows)
• Security (preventing unauthorized access)
• Ventilation control
• Regulatory compliance (building safety standards)

 Key Specifications & Technical Details

When choosing a Mr.Goodbar keyed restrictor, consider the following technical specifications:

 1. Opening Limit

• Most restrictors limit the sash opening to about 100 mm – 150 mm, enough for ventilation but too narrow for a child to fall through.

 2. Load/Force Capacity

• Models are tested to withstand several hundred to a few thousand Newtons (e.g., ~300 kg horizontal force).
• That load rating shows how much force the restrictor can resist before failure (important for security and safety).

 3. Materials & Durability

• Mr.Goodbar Window restrictors use stainless steel, high-tensile cables, and corrosion-resistant finishes for longevity.
• Environments with moisture (bathrooms, coastal areas) benefit from marine-grade materials.

 4. Locking & Keying

• Keyed alike vs. keyed different:
  • Keyed alike: One key operates all units (more convenient).
  • Keyed different: Each restrictor has its own unique key.

 5. Compatibility

• Ensure the restrictor fits the window frame material — uPVC, wood, aluminum, steel, etc. — and mount type (surface mount vs. euro groove).
• Measure sash and frame thickness before buying.

 These Mr.Goodbar window restrictors are typically surface-mounted restrictors intended for safety/childproofing, not high-security primary locks.

 General Installation Steps

Note: Always follow the specific product’s instructions if included. The following steps are a general guide.

1. Plan & Mark

• Decide the restricted opening distance (e.g., ~100 mm).
• Mark the window frame and sash where the restrictor will mount.
• Ensure the restrictor isn’t in the path of handles or other hardware.

2. Pre-Drill Mounting Holes

• Use a drill and appropriate bit for your frame material (wood, metal, PVC).
• Anchor points must be solid and stable.

3. Attach Mounting Plates

• Fix the restrictor body to the stationary trim or sash frame.
• Install the counterpart plate on the moving sash.

4. Install Hardware & Test

• Assemble the restrictor (cable, bar, or lock) per instructions.
• Test multiple cycles: open to limited position, lock, unlock with key, ensure smooth operation.

5. Secure Screws and Final Check

• Tighten all screws securely (don’t over-tighten to strip threads).
• Check that the window still closes and latches correctly.

 Installation Tips & Safety Notes

 Height placement: Mount restrictors out of easy reach of small children but accessible to adults.
 Test regularly: Inspect every 6–12 months for loosening or wear.
 Do not impede escape: In bedrooms or fire escape scenarios, check local codes — keyed restrictors may not be allowed where the window is needed for emergency egress.
 Use correct screws: Match screws to your frame material (metal vs wooden frames).
 Avoid DIY “makeshift” restrictors: Zip ties, ropes, or blocks aren’t safety-rated and can fail unpredictably.
