Heavy Sockets Can Fall Off

Quotes from Harbor Freight reviews for the 1/2" socket rail.

"These work great for smaller to medium sized 1/2 sockets, but the bigger, heavier sockets fall off. Not bad thou."

 "I got a strip to hold the 13 peice deepwell impact set and they just fall majorly short on holding power. If you can turn the rail straight sideways and let the sockets hang vertically they stay but as soon as you rotate the rail at all the sockets weight just peels them right off.. Oh well, never know till ya try right"
