Spring clamps are convenient wherever relatively light pressure is adequate and speedy application and removal are important. Spring clamps are designed as a quick and easy answer to many clamping needs in the home, workshop or on the job site. The "XM" series is BESSEY's steel spring clamp line. Versions with a -B suffix have a non-reflective flat black finish with black vinyl grips and tips. Great for photography and film studios. BESSEY. Simply better.
