I could NOT find ANYWHERE where the maximum weight capacity is listed. If you're looking for it: it's 20 pounds. for the bracket. It's listed on the back of the package but I have no idea why it wasn't listed on any sites I looked up. Anyway these are plain clips and they are a bit rough so I bought a black plastic tin. -dip to make my tools and I found this to be a good item as it would give good coverage of the rubberized paint with minimal slippage. Now they are almost perfect. if only they could handle a slightly heavier load of up to 30-40 pounds.
