45x60mm Frame Packers

45x60mm Frame Packers are Type J installation packers designed for supporting and aligning window and door frames during fitting.

With a 60mm length and 45mm width, these packers provide a wider support area than many standard frame packers. This makes them useful where installers need stronger bearing support behind the frame, particularly around fixing positions, hinge areas, locking points, or wider frame sections.

The U-shaped design allows the packer to be positioned around the fixing area, helping support the frame while the fixing is tightened. This helps reduce the risk of outer frame distortion and allows the frame to be installed plumb, square, and correctly spaced.

Made from polypropylene, these packers are rigid, durable, and suitable for professional trade installation work.

Why installers choose 45x60mm Frame Packers:

• Wider 45mm support face for stable frame packing
• Useful around fixing points, hinge areas, and locking points
• Helps prevent frame distortion when fixings are tightened
• U-shaped design allows fitting around the fixing area
• Suitable for window and door frame installation
• Wide thickness range from 1mm to 10mm for flexible adjustment

These 45x60mm frame packers are a versatile option for installers who need a wider frame packer with multiple thickness choices, from fine 1mm adjustments through to larger 10mm spacing requirements.

What Each Thickness is Used For

1mm – Fine Frame Setting

Used where the frame is almost correctly positioned and only a small correction is required.

Best for:

• Final frame alignment
• Fine gap correction
• Small adjustments around fixing points
• Layering with thicker packers for exact spacing

2mm – Light Spacing & Minor Correction

Useful when the frame needs a small but noticeable adjustment.

Best for:

• Light frame packing
• Small gaps behind the frame
• Minor levelling corrections
• Controlled adjustment before fixing

3mm – Standard Frame Packing

A common thickness for everyday window and door fitting work.

Best for:

• General frame support
• Packing around fixing points
• Routine alignment work
• Keeping the frame square before final tightening

4mm – Medium Adjustment

Used where the opening or frame position requires a more noticeable spacer.

Best for:

• Medium gap correction
• Supporting wider frame sections
• Levelling frames in uneven openings
• General trade installation work

5mm – Stronger Gap Support

Provides firmer support for larger gaps or more demanding fixing areas.

Best for:

• Larger frame gaps
• Extra support near hinges or locking points
• Building out frames before fixing
• More significant alignment correction

6mm – Heavy Frame Packing

Used when a thicker support packer is needed behind the frame.

Best for:

• Wider installation gaps
• Stronger support around fixing points
• Uneven structural openings
• Keeping larger frames properly positioned

10mm – Maximum Spacing & Deep Gap Support

The thickest option in this range, used where a substantial spacer is required.

Best for:

• Deep gaps between frame and opening
• Larger frame build-out requirements
• Heavy-duty support areas
• Installations where 6mm is not enough
