This product is identical to the SafeRacks product. I own both, as well as the GearLoft racks. I bought this because SafeRacks was out of stock. Everything down to the instruction booklet is identical between MonsterRax and SafeRacks.i bought both the SafeRacks 2'x6' (qty 1) and 3'x6' (qty 3) as well as the Overhead GearLoft 2'x4' (qty 4). I bought both brands because neither brand had all three sizes, and i needed all three. I am very happy with both. Overall, I like the Gearloft better -- it is easier to assemble, has a tighter "grid" on the base, and the grid is permanently affixed to the base, whereas the SafeRacks grid floats/slides on the base horizontally. I feel like the gearloft is a bit sturdier as well.That said, the SafeRacks is no slouch, and i dont regret the purchase in the least. The minimum height from ceiling to the bottom of the base (i.e., if you only use one vertical support per corner, instead of two bolted together) is exactly 24.5" Below two of these racks, I have some pegboard on the wall at exactly 2' below ceiling, and these racks covered the top 1/2" of the pegboard, which works out fine. The other racks I have extended to about 33" (ceiling to bottom of base) as I have more room in that area.First pic shows one of the corners of the 2'x6', next pic shows how the SafeRacks vertical supports are bolted in order to extend the height (the GearLoft is in the background here). The third pic shows the bottom grid as well as some deck hooks (purchased separately and much cheaper from SafeRacks' website). The fourth pic shows SafeRacks (left) and GearLoft side by side. The fifth pic shows the GearLoft vertical support extender mechanism -- much easier than the SafeRacks, which have to be bolted -- but still very sturdy -- the more weight on the rack, the more solid the connection between the two supports. The last pic is a view of the GearLoft base/grid which is fixed. In the seventh pic, you can see I have hung my (very heavy) wheel barrow from the corner with a utility hook (also purchased separately in the same hook accessory package direct from SafeRacks).I weight 200lb. and can put my whole weight on any corner of any of these racks and it is solid. Just make sure you anchor into a joist on both ends of angle bracket, with vertical support in between the two and you'll be fine. Actually on two of them, i actually anchored two of the GearLoft horizontally into a glue-lam beam than juts down 4" below the ceiling height (eighth pic). That worked great as well. In retrospect, i could have just anchored directly into the beam without the top angle bracket.Bottom line, buy either of these manufacturer's product with confidence. They are both awesome. No regrets with either.I subsequently bought MonsterRax 6x3 because these were out of stock. MonsterRax is the identical product as SafeRacks. See my SafeRacks review for photos.
