Ironmaster Quick-Lock Adjustable Dumbbells 75 lb

The Ironmaster Quick-Lock Adjustable Dumbbells use a patented threaded spinlock mechanism that secures solid steel weight plates to a solid chrome-plated handle with a quarter-turn locking collar, providing the same solid, compact feel as fixed steel dumbbells in a product that adjusts from 5 lbs to 75 lbs per dumbbell in 2.5 lb increments with the addition of the optional add-on kit. Unlike plastic cradle-based adjustable dumbbells, the Ironmaster Quick-Lock uses solid steel plates that stack compactly and do not rattle or shift during aggressive training movements. The handle dimensions remain constant across all weights, maintaining consistent grip position. The plate change process takes approximately 15 seconds per dumbbell. The solid steel construction withstands dropping and throwing that destroys plastic-housing alternatives. Lifetime warranty.
