Add On Kit To 120-Pounds For Quick Lock Dumbbells

The Quick-Lock Dumbbell Add on Kit is made to bring your workouts up to several notches higher by adding 45 lbs to each dumbbell to bring them up to 120 lbs each. Includes four longer locking screws and four 22.5 lb weight plates. This is not the full set of dumbbells – only an add on kit. The image on the stand with a full set is for illustration purposes only.

What is a Adjustable Dumbbell?

What adjustable dumbbells are

Adjustable dumbbells replace a whole rack of fixed dumbbells with one pair whose weight you change via a dial, pin, or selector plate. They are the space-and-money saver for home gyms: a single set can span roughly 5–50+ lb per hand. The trade-offs are bulkier handles, a fixed max weight, and a mechanism that can wear or rattle.

What to look for

Fast adjustment (dial or lever beats stacking plates), a wide and useful weight range, a balanced feel that doesn’t clunk mid-rep, and a durable locking mechanism. Many sets include or offer a stand — worth it, since the blocks are awkward to load off the floor.
