Spring Frame Packers
Spring Frame Packers – Self-Holding Packers for Window & Door Frame Installation
Spring frame packers are specialist frame packers designed to help installers position and support window and door frames more easily during fitting.
Unlike a standard loose frame packer, a spring frame packer is shaped to apply light pressure inside the gap between the frame and the structural opening. This helps the packer stay in place while the installer aligns the frame and prepares the fixing. This can be especially useful when working around fixing points, fitting frames in awkward positions, or installing windows and doors where the packer may otherwise slip, rotate, or fall out before the fixing is tightened.
Spring frame packers help keep the frame correctly spaced, plumb, and square during installation. They are suitable for professional window and door frame fitting across uPVC, aluminium, and timber systems.
Our spring frame packer range includes 42x50mm and 42x60mm options in multiple thicknesses. Add the products you need to your quote request and we’ll confirm pricing, availability, and delivery time before you order.

What Makes Spring Frame Packers Different?
Spring frame packers are designed to make frame installation easier by helping the packer stay in position before the fixing is fully tightened.
With a standard frame packer, the installer may need to hold the frame, packer, and fixing at the same time. A spring frame packer helps reduce this problem by gripping lightly in the gap, making it less likely to drop out or move while the frame is being adjusted.
This makes them useful for:
- Holding the packer in position during frame fitting
- Supporting window and door frames around fixing points
- Reducing packer movement before screws are tightened
- Helping keep the frame plumb, square, and correctly spaced
- Working in awkward areas where loose packers are harder to manage
- Installations where the installer wants a quicker, cleaner fixing process
The 42x50mm spring frame packers are useful where a compact self-holding packer is required. The 42x60mm version gives a slightly longer support area where extra bearing length is preferred.
Choosing the Right Spring Frame Packer
Choose the spring frame packer size based on the available space behind the frame and the amount of support needed around the fixing point.
- 42x50mm spring frame packers are a compact option for common fixing areas and general frame installation work.
- 42x60mm spring frame packers provide a longer support area and can be useful where the installer wants more bearing length behind the frame.
Choose the thickness based on the frame-to-opening gap. Thinner packers are useful for fine adjustment, while thicker packers provide more spacing and support where the gap is larger.
Spring Frame Packers – FAQs
Spring frame packers are used behind window and door frames during installation. They help support the frame, maintain the correct gap, and stay in position while the frame is being aligned and fixed.

They are useful when you want the packer to stay positioned while you align the frame and install the fixing. This can make fitting easier, especially in awkward areas or when working around fixing points.
Choose 42x50mm where a compact spring packer is enough. Choose 42x60mm where you want a slightly longer support area behind the frame.
Choose the thickness that fills the gap without pushing the frame out of alignment. Use thinner packers for fine adjustment and thicker packers for larger gaps.
