The SAMSplint is built from a thin core of aluminum alloy, sandwiched between two layers of closed-cell foam. Bent into any of three simple curves, it becomes extremely strong and supportive for any fractured or injured limb. The SAM Splint is incredibly lightweight (only 4.0 oz.). No other device offers so many variations for the treatment of orthopedic emergencies. Also available is the SAM Splint XL at 5.5" wide, for improved support and immobilization of larger individuals.
