Flat Packers – Mixed Packs & Tubs – 1mm-6mm

Mixed flat packers are one of those things you don’t think about until you need one urgently and can’t find it. These packs give you a spread of thicknesses from 1mm through to 6mm, so whatever the gap, you’ve got something that fits. Whether you’re hanging a door frame, setting window boards, or levelling out a sole plate that’s decided to go its own way, having a mixed selection to hand means you’re not running back to the van three times.

Each pack contains a mix of sizes across the 1mm to 6mm range. The 1200-piece tub gives you 200 of each thickness, so you’re covered for larger jobs or if you want a stock that actually lasts. The smaller mixed packs are handy for keeping in the toolbox without taking up half of it. The packers themselves measure 100 x 28mm, which is a practical size for most frame and fixing applications.

Where Mixed Flat Packers Get Used

These are a daily-use item for joiners, first fixers, window and door installers, and general builders. Setting door frames plumb and square, packing out window reveals, levelling structural timbers, shimming kitchen units, adjusting stud partitions — the list is long. Bricklayers use them too, particularly when bedding in lintels or levelling coursework off an uneven base.

Getting the Combination Right

The real advantage of a mixed pack is being able to combine thicknesses. Two 2mm packers plus a 1mm gets you to 5mm without hunting for a single 5mm packer. That flexibility speeds up the job and reduces waste. Having all six sizes in one pack is what makes this a proper working tool rather than a single-use buy.

At this price point and with genuine bulk quantities available, keeping a tub of mixed flat packers on site is just straightforward sense. The kind of thing that earns its place by quietly solving small problems before they become arguments with a spirit level.
