50x50x3.3mm Klip Frame Packers

50x50x3.3mm Klip Frame Packers are designed to help installers support and align window and door frames while keeping the packer securely positioned during installation.

Unlike a standard frame packer, the klip design helps grip around the fixing area and reduces the chance of the packer rotating, slipping, or falling out while the frame is being fitted. This is especially useful when working at height, in awkward positions, or where the installer needs both hands free to place and tighten the fixing.

The 50mm x 50mm body provides a compact but stable support area, while the 3.3mm W2 profile makes these packers suitable for applications where this klip format is required. Made from polypropylene, they provide firm support and are suitable for professional window and door frame installation work.

Why installers choose 50x50x3.3mm Klip Frame Packers:

• Klip design helps hold the packer around the fixing point
• Reduces the risk of packer rotation or movement during fitting
• Installation tab helps with easier positioning on site
• Useful when working at height or in restricted fitting areas
• Helps support the frame while fixings are installed
• Suitable for window and door frame installation

These 50x50x3.3mm klip frame packers are a practical choice when installers want a compact frame packer that stays in position more securely than a loose standard packer.
