Includes a mix of 10mm, 6.5mm, 5mm, 3mm & 1.5mm packers.

Covers up to 16mm of packing and up to 5 1.55m long sleeper lengths.

Excaliber sleeper packers are used when installing the first sleeper level of your retaining wall installation. If one corner of your concrete has set a few mm short, you can level this base sleeper by inserting the required mm width packer- or packer combination to achieve a level sleeper base, making sure that your whole bay will remain level.
