## Customer Reviews

### ⭐⭐⭐⭐⭐ You Won't be Disappointing
*by C***O on September 7, 2020*

Got this this hang a 150-lbs heavy-bag on my I-Beam so that I could roll it out of the way when I'm done. It works perfectly. Easy to install, easy to roll away, but very stable when you lock it in place. You can tell as soon as you take this out of the box it is a quality made product. I would highly recommend it!.

### ⭐⭐⭐⭐⭐ Excellent for home gyms/very well made
*by B***. on April 2, 2016*

I have two Firstlaw Fitness I-Beam Rolling Punching Bag Mount. My I-beams are 7.25 inches wide and I have 10 foot ceilings. It is also important to note that I have exposed TJI floor joists, and manufacturer recommendations are very clear that home owners are not to drilling holes in TJI joists (very easily can compromise the integrity of your joists... and my GC agreed and strongly urged me to avoid drilling into my TJI joists). So, after much research, I decided to purchase the Firstlaw I-Beam rolling mounts, and could not be happier. My nine year son can easily move both my heavy bags (120 pound KO Muay Thai/Tear Drop bag and 150 pound Outslayer Muay Thai bag - I also have a junior KO Muay Thai bag on a tradition cheaper i-beam mount, which I do not like more many reasons). My wife loves the rolling mount system because both of my bags can be very easily moved out of the way when she is working out, lifting, doing cardio, etc. I have all three of my bags on the same I-beam and move them back and forth for training purposes. This product seems to be very well engineered and constructed, and easily installed (took me ten minutes for the first one and five for the second). I strongly recommend this product, plus it's a USA made product (PA based).

### ⭐⭐⭐⭐⭐ Sturdy product and easy to install
*by M***S on August 22, 2020*

This product works great in my I beam and was easy to install. It really makes moving my boxing bag a lot easier and I can better utilize my workout space for other things.
