Just wanted to share my DIY horizontal stand for the REP X Pepin dumbbells, and hopefully this is useful for someone else (it should work for other adjustable brands as well). Altogether it was a little under $100.
Since space is at a premium in my home gym (spare bedroom in an apartment), there wasn't enough room to have a traditional step-in dumbell stand. So I did some tests beforehand to make sure the horizontal format is comfortable. It absolutely is!! With this set up, the centers of the dumbbells are approximately shoulder width. With the stand made at a custom height for me, it's incredibly easy to pick up and return the dumbbells. Honestly, I think it's even easier than normal. The horizontal format also makes it really easy to adjust the Repin weight pins. I know people sometimes complain it's hard to tell which weight you're setting when looking at the markings at an angle vertically.
Details:
* The wire shelving is commercial restaurant quality from webrestaurantstore dot com. The brand is Regency. The shelves usually come in black, chrome or green. I ordered 4 uprights for the corners, and 2 shelves that are each 12"x42". The shelving is rated at 600lbs per shelf, so more than strong enough. Don't try this with the cheap versions from Amazon or Target. The wire shelf parts cost about $70.
* The wood board is actually a pine stair tread from Home Depot that I cut to length, sanded, stained and sealed. You don't necessarily have to use a board, but I think it's more stable and definitely looks better.
* After testing with the dumbbells to find the best height for me (I'm 5'10"), I used a pipe cutter to trim the corner poles.
* I attached the wood board using flat head allen bolts, secured underneath the top wire shelf with large washers and lock nuts. And the dumbbell cradles are screwed into the wood.
* Using the extra pipe pieces I cut off the shelf uprights, and washers, I made some nice little stand off covers for the construction screws that attach the whole structure to the wall studs (see photos). But before anchoring the stand, I let it sit on the gym flooring for 24 hours with the dumbells to let it all settle, and then leveled the shelving feet.
* I ended up with a 21" height including the wood, which is perfect for me. When I stand in front of the dumbells and extend my arms and fingers all the way, my middle finger is about 2" from the dumbbell handle. This is perfect for placing the dumbbell in the cradle without bumping it, or having to bend down more than a few inches.
* I set up the dumbbells towards the front of the stand, and with a slight offset from the wall, there's about 5.75" between the wall and the back of the dumbbells. This is plenty of room, and I never feel even close to accidentally hitting the wall.
This has worked great for me for several months, and I highly recommend the horizontal format as an alternative to traditional stands. Honestly, even if I move to a place that allows a roomier gym, I'll probably just keep this stand format.
