Decades of perfection – Ironmaster old quick-lock design was sold to Hoist. While it was quicker to change than the current design,  it wasn’t as safe as a combination of chipped paint and a slightly loose pin would increase the chance of the plates dropping on your face.

1 review for Ironmaster 75 LB Quick-Lock Adjustable Dumbbell Set – No Stand

  1. Josh Coverley

    Absolute quality dumbbells.

    Solid construction, no rattling, look amazing, grip extremely perfect knurling.

    Was worried changing weights would be slightly annoying but surprisingly fast … and satisfying (might just be me)

    At first length of grip ( quite long compared to normal ) felt a bit strange but quickly got used to it. May get the add-on that addresses this.

    100% satisfied with the purchase.

    Thanks Sam’s fitness and iron master
