The exclusive Defender Series “Safe Lock” Chuck expands the capabilities of our axial side load core chucks by resolving any potential risk of the core not fully tightening and ensuring the roll is always perfectly concentric. By preventing the lugs from engaging until the roll is fully pushed against the flange of the chuck, the risk of cores not being 100% tightened against the chuck is eliminated, ensuring maximum safety and gripping performance for reduced downtime, reduced core damage, maximum safety, and higher performance.
