Using these wrist restraints is easy. Just wrap the cuffs around the wrists and adjust to the right size using the six available adjustments. They're great for stretcher or gurney applications. When removing, it's a quick process thanks to the non - locking design. Make sure to check the control straps regularly as they are permanently riveted, but any signs of damage should be addressed immediately. For cleaning, follow the standard cleaning instructions for leather and polyurethane products. If you're using the optional foam padding or the disposable fleece liners, replace them as needed for continued comfort and hygiene.
