ABT 3D Security Flag Hinges

Overview
The ABT 3D Security Flag Hinges are engineered for professional use in window and door installation where enhanced security and precise adjustment are essential. Suitable for timber and composite sashes, these flag hinges accommodate sash weights up to 26.6kg per hinge, making them appropriate for medium-weight window or door units. Their three-dimensional adjustment capability allows for fine-tuning in lateral, vertical, and compression planes, facilitating accurate alignment and smooth operation post-installation. The hinges feature a compact design with a 30mm height and 40mm width, optimised for fitting within standard frame profiles that incorporate a 16mm profile step.

Key Features
• Height: 30mm; Width: 40mm; Projection: 43mm – designed to fit within typical stepped sash profiles
• Profile step height: 16mm – compatible with sash rebates requiring this specific step dimension
• Distance between pins: 70mm – ensures consistent pivot action and durability under load
• Supports sash weight per hinge up to 26.6kg – suitable for medium-weight windows and doors
• 3D adjustment capability for precise lateral, vertical, and compression alignment on-site
• BS rated – compliant with relevant British Standards for enhanced security applications
• Supplied bagged for efficient handling and inventory management

Fitment & What to Check
When installing the ABT 3D Security Flag Hinges, verify that the sash rebate profile step height matches the hinge’s 16mm specification to ensure proper seating and weather sealing. The 70mm distance between pins must correspond with the existing hinge mortice or frame preparation for correct fit and reliable operation. Confirm that the sash weight does not exceed 26.6kg per hinge to maintain mechanical integrity and avoid premature wear. The projection of 43mm should be considered in relation to frame depth to prevent interference with adjacent components. After installation, utilise the 3D adjustment features to achieve optimal alignment and smooth sash movement.

Common Ordering Mistakes
• Selecting hinges without confirming profile step height compatibility, leading to poor sealing or misalignment
• Exceeding the maximum sash weight per hinge, which reduces hinge lifespan and affects security
• Assuming all flag hinges have identical pin spacing, resulting in incorrect fitting or additional frame modification
• Overlooking the BS rating requirement for security-critical applications, potentially compromising compliance
