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. Nickel plated to resist corrosion with vinyl tips and handles for improved grip. Versions with a -NPT suffix are also nickel plated but without any vinyl grips & tips. BESSEY. Simply better.
