Fred Corner Protectors are thin enough to use 2 on most corners - on the top and the bottom to give maximum protection from falls and bumped heads. The curved, 2-component design and rigid inner shell designed to bind with the Fred SecureHold adhesive keep protectors firmly in place, and a softer shock-absorbing outer layer to ensure excellent impact protection - and still thin enough to fit 2 to table corners (minimum 16mm thick).
