I was looking for a better way to store my glass carboys for brewing. I like to hang stuff like ladders, 2x4 storage, pipe storage in the rafters in the garage and i thought that may be a good solution for the carboys too. They hang a bit low but as long as you put them towards the walls or in corners or over rifrigerators, you don't run into them too often. Hanging them also makes them more secure than just setting them on shelves or on top your fridge. This also allows them to drip dry without the water puddling. I've been using these for over a year now without any problems or breakages. I can't account for every material you may use so be careful.
You dealing with glass carboys and power tools. Keep them away from eachother while building. the carboys are dangerous enough as is. Be carful when hanging them and especially when getting them down. A ladder or step stool is the best bet if you can't reach your ceiling. There are plenty of horror stories about people almost dieing from broken carboys. Please be careful. Do no hange full carboys. This meathod is meant for empty ones to hang for drying and storage. Not for full ones for transfering liquids.
