TO PUT ON (Psst...it's so simple!)

  1. Remove any sharp jewelry and smooth out all rough edges on your cast to prevent tearing the Bloccs diaphragm.
  2. Using your thumb, stretch the opening to make room to insert your cast.
  3. Insert your arm into the Bloccs cast cover.
  4. Gently remove any air from the protector by holding the seal open as you slowly lower your arm into the pool. The pressure of the water will push out the air through the seal at the top. Once all the air is out, slowly release the seal and make sure it's tight and smooth all around your arm. 
  • Use for up to 30 minutes at a time with 15 minute breaks.
  • Regularly check the cast cover to ensure the seal is intact and watertight.
  • Not intended for long distance swimming or diving.


  1. Come out of the water.
  2. Gently release the seal.


Wash in warm water.
Dry carefully inside and out.
Never place the protector in the dryer.

Contains latex.

Bloccs is a single patient use medical product. Please do not share your cast cover.
