42x60mm Spring Frame Packers

42x60mm Spring Frame Packers are designed to make window and door frame installation easier by helping the packer stay in place while the frame is being fixed.

With a 60mm length and 42mm width, these Type M spring frame packers provide a longer support area than the 42x50mm version. This makes them useful where installers want extra bearing length behind the frame while still benefiting from the spring-action design.

The spring feature applies lateral pressure between the outer frame and the structural opening. This helps reduce packer movement during installation and can make the fixing process easier, especially when working in awkward positions or where holding the frame and packer at the same time is difficult.

Made from polypropylene, these packers provide firm, reliable support and help keep the frame correctly spaced, plumb, and square before final tightening.

Why installers choose 42x60mm Spring Frame Packers:

• Longer 60mm profile for extra frame support
• Spring design helps hold the packer in position
• Useful where the packer needs to stay in place while fixing
• Helps reduce rotation or movement during installation
• Supports frame alignment around fixing points
• Suitable for window and door frame fitting

These 42x60mm spring frame packers are a good choice when you need a longer support packer with the added benefit of spring retention during frame installation.

What Each Thickness is Used For

1.5mm – Fine Spring Packing

Used when the frame needs a small adjustment while keeping the packer held in position.

Best for:

• Fine frame alignment
• Small gap correction
• Final positioning before fixing
• Light support where packer movement needs to be reduced

3mm – Everyday Frame Installation

A practical thickness for general window and door fitting work.

Best for:

• Standard frame spacing
• Supporting the frame around fixing points
• Light-to-medium gap correction
• Keeping the frame positioned while fixings are installed

5mm – Stronger Gap Support

Used where a thicker spring frame packer is needed for more noticeable spacing or alignment correction.

Best for:

• Medium frame gaps
• Firmer support behind the frame
• Uneven openings
• Installations where a stronger hold and larger adjustment are needed
