Here are the reasons Ironmaster Quick-Lock Dumbells are better than other adjustable dumbells (powerblock, bowflex):

1. Ironmaster Quick-Lock Dumbells are rugged. The handles are made out of solid steel with welded construction. The weight plates are precision machined iron. They can be used hard dropped without damage. Others are fragile and can break if dropped since they contain light duty and plastic materials. This may not be covered in their warranty. Ironmaster Quick-Lock Dumbbells carry Lifetime Warranty against breakage!

2. Others are limited in the exercises you can do with the restricted access to the handles. They will bind your wrist in some motions! Ours are wide open like a traditional dumbell and allow unlimited exercises.

3. Others use a pin assembly or tiny cams to hold the weights. These can wear and loosen up over time and pins can fall out during use making them dangerous. Ours are held together with a super heavy duty 1" dia. threaded screw mechanism. Once tightened, they will not loosen during use since the plates are locked into the handle backing plates and can't spin. Plate change is quick and simple. Ironmaster dumbells do not rattle or feel loose. In fact they work and feel like a solid fixed weight style dumbell.

4. We offer an Add On Kit for the 75lb Quick-Lock Dumbells to go up to 120lbs each! The optional rack accepts this kit and it can be added later at any time. The kit is very simple to use.

5. Our dumbbell handles are chrome plated, knurled steel just like traditional dumbells. No rubber or foam grips to wear out or harbor bacteria.

6. Ironmaster Quick Lock dumbbells is that the locking screws have large rounded flat ends. This allows you to rest the dumbbells on your thighs and hoist them into place when you are doing heavy dumbbell training.

7. Designed with usability and practicallity in mind, Ironmaster dumbbell are not the most fancy but provide the best usage experience.

Before they realize the cost and space associated with racks of fixed dumbbells, customers often state they don’t want the hassle of changing weight plates. The Ironmaster Quick Lock Dumbbells are a far cry from the old spinlock dumbbells that I think we all started out with. The patented Ironmaster Quick Lock system requires only a ¼- 3/4 turn and the locking screw slides straight out. The weight plates are hand machined and interlock so they don’t fly everywhere when the locking screw is out. The end result is that you can easily change weights in less than 30 seconds. This will give you something to do between your sets unless you are the kind of person who likes to gaze longingly at yourself in the mirror. Unlike the old spinlock dumbbells, the locking screws on the Ironmaster Quick Lock Dumbbells will not work their way loose through your set.

The Ironmaster Quick-Lock Dumbbells come with a optional handy stand that not only keeps your dumbbell set nice and neat but it is designed to aid quick weight changes. The stand will also accommodate the Ironmaster Add on Kit if you decide to add these to your gym.

Quick-Lock Dumbbell FAQs

Q: How long has Ironmaster been in business?
A: We have been building the very best weight lifting equipment for over 33 years. We have continued to advance our designs over the years with innovative engineering to offer the best equipment money can buy.

Q: How easy is it to change the weights on the Quick-Lock Dumbells?

A: A weight change takes only 5-10 seconds! All it takes is a partial turn of the locking screws on the ends of the dumbbells to add or remove weights. A normal 10-20 lb weight change on both dumbells only takes about 30 seconds.

Q: How heavy-duty are the Quick-Lock Dumbells?
A: The dumbbells come with a lifetime warranty. They are built super strong from solid steel and iron with all welded construction. You can work out hard, do any dumbell exercise and drop them without damage.

Q: Why are the weight plates on the Quick-Lock Dumbells square?
A: The plates are specially formed and machined to interlock together and onto the handles which prevents them from spinning. The square shape is also nice since they will never roll away from you and make them more compact when swinging close to the body.

Q: How safe are the Quick-Lock Dumbbells?
A: The special retaining screw design is very safe. The only way to release the weights is to manually turn the locking screw to the exact open position. The weight plates interlock and are held tightly against the chrome backing plates that are welded to the handle. The plates can not rotate which is the cause of normal dumbbells becoming loose. You know the dumbbells are locked by just looking at the engraved marks on the handles and because everything is held tightly and there is no looseness or rattling. You can feel free to use the dumbbells overhead and in any orientation you like.

Q: How complete of a workout can I get using dumbells?
A: With a full set of dumbells and a good adjustable bench, you can work every muscle group. Free weights are, and always have been, the ultimate way to build muscle and shape the body. Check out our exercise chart and workout routines for some examples.

Q: How accurate are the weights?
A: The weights listed for the Quick-Lock Dumbbells are a nominal value. There will be some variability in the weight plate castings due to density changes in the cast iron as well as the machining process. The primary tolerance held in manufacturing for the weight plates is the thickness and shape so they will lock up correctly and safely on the handles. Most dumbbells will be within 3-4% of the stated weight.

Q: What maintenance is required for my dumbbells?
A: There is no required maintenance, however, it is helpful to clean out the threads inside the dumbbell handles a couple times a year in case dust or particles get trapped and apply a lighy lubrication to the threads. A good way to clean the internal threads is with WD-40 lubricant type spray and then pull a small rag through or blow out with compressed air. A light spray of WD-40 or similar lubricant on the locking screw threads can also help thing turn smoothly. The weight plates are enamel painted cast iron and may develop scratches or small chips with use. This does not affect the performance, but they may be spray painted semi-gloss black to give them a new appearance again if desired.
