Ironmaster Quick-Lock 165 lb Add-On Set (Single)

Overview

The Ironmaster 165 lb add-on set exists for the lifter who already owns a Quick-Lock 75 and discovered that dumbbell presses got easy. Rather than buying an entirely new set, this kit supplies the additional precision-milled steel plates that stack onto the existing Quick-Lock handle, extending each dumbbell from 75 up to 165 pounds per hand. The genius of the Ironmaster system is its rock-solid plate lock: a single captured locking screw clamps the plates into one rigid unit with zero rattle, so even at 165 pounds the dumbbell feels like a fixed cast piece rather than something assembled. Plate changes are slower than a dial or pin system, which is the deliberate trade Ironmaster makes for durability and a slim, balanced profile that fits a narrow grip. The plates are bare steel and built to be effectively indestructible, and they nest on the locking stand if you own it. This is a single-handle add-on by design, so most buyers purchase two kits to upgrade a full pair. For heavy, no-rattle dumbbell work, nothing else feels this solid.
