Using these humane non-locking leather restraints is a breeze. First, decide which size you need as they have six size adjustments to fit from juveniles to adults. You can put them on beds, gurneys, chairs, or use them in ambulatory situations. Just wrap the cuffs around the person's wrists or ankles and secure them with either the 1¼' non - locking or locking belts. For added comfort, you can line the cuffs with the standard orthopedic leather lining or add the optional foam padding. You can also use the disposable fleece liners FWL - 200 for wrists and FAL - 200 for ankles. When it comes to maintenance, keep the leather clean and dry. Wipe it gently with a soft cloth. Avoid exposing it to excessive moisture or direct sunlight. If the fleece liners get dirty, just replace them with new ones.
