Packers are also called Construction Packers or Panel Packers. These products enable accurate adjustments for levelling up to the slightest mm before grouting. Packers and frame packers are used for covering minor packing, spacing, and shimming jobs. Wedges and shims provide support and fine adjustment. Shims may also be used as spacers to fill in gaps between objects or parts of objects. Although typically used to secure doors and windows, these products can be used in many other applications, both indoor and outdoor. Modern-day moulded plastic packers can be used in wet or dry conditions and a wide range of applications. These are versatile products that do not split, shrink, rust and rot and are completely waterproof.
