Shims to use with our Squarebound Protector
These shims will help adjust certain books to use with Squarebound Protector. Not every book will need shims.
Each shim will fit both the 3mm and 6mm Squarebound Protector.
We recommend using our shims for around 25-30 presses before replacing.
Wipe off all frames and shims with a damp paper towel or micro fiber cloth before your first use. These could bear some smoke residue from the laser cutting manufacturing process.
