Rubber Dumbbell stand – Dumbbell Storage rack, Perfect For 5-30 lbs Set – 2 Tiers & 2 Vertical Slots With Protective Inserts – Compact & Versatile Design, Max. Weight 400 lbs.

Very easy to assemble and solid when put together.I use round weight plates and can only get two dumbbells on each side, I guess if you use hexagonal weights you would get four on each side. It’s the gap between the recess but if using light weights with small plates will get four easily.Regardless of that there is plenty of space on the shelves for the weights.It has cleared a large area in gym so I am happy with the rack.

Overall this is a pretty good quality product, but got to say that I'm really disappointed with the fact that you have to remove the top 3 tiers of dumbbells if you want to use the ones on the bottom of the rack. Each hex dumbbell is basically sat on the one below (rather than being fully supported by the rack).

1. Screws are relatively loose and impossible to tighten without the right tools (which are NOT included, which is pretty much an expectation with these kinds of items).2. The rubber bands on the middle rack are sized incorrectly and come off constantly.3. There are SHARP screws sticking out on both sides of every single weight compartment, so when you want to take a weight off the rack, you have a 50/50 chance of getting stabbed with a free dose of tetanus. Simply dangerous design.4. Impossible to return if you don't have a printer.0/5 stars. Do not buy.
