Freedom Clark Socket from AliMed You don't need to scramble to find a specific socket — this Clark Socket has you covered. The first and only Clark Socket that holds flat and round posts and rotates 360° makes surgical setups quicker and easier, says the company. Not only does it accept both flat and round posts, but it also snaps at any point along the side rail, even between other clamps. This lets you add accessories during a case without disturbing the other instruments already in place. It includes degree marks for quick, reproducible setups. It even has a smooth, ergonomic handle. $254, www.alimed.com
