Designed to be fully submergible Bloccs® Covers are invaluable whenever and wherever you need waterproof cast or dressing protection — whether pool, beach or bath.

Bloccs® easily stretch over casts and dressings to make a watertight seal.

Please follow the sizing chart. Bear in mind that extra length is okay, the circumference measurement needs to fall comfortably within the range given. To achieve the best fit, you may need to consider both adult and child sizes. 

  • Measuring is the key to a great fit!

    Our elbow PICC line and dressing protectors come in a variety of sizes to fit both children and adults. To ensure a watertight fit, be sure to
    follow these steps

    STEP 1: Measure for the right cover length.

    Measure from the forearm to the bicep to get the minimum length of the elbow protector needed.

    STEP 2: Measure for a watertight seal.

    Measure around the arm at the bicep (A) and at the forearm (B).

    STEP 3: Check the Size Chart.

    From the Elbow sizing chart, choose the Bloccs® cover which will fully fit over the elbow dressing.

    Size is determined by the seal size not the length. The larger size elbow protectors have a larger seals around the arm and are shorter in length.
