肘部支架

The fit is dead-on precise whether you grab the 4000 or the other series, so no wobble once everything's torqued down. I spent an afternoon rearranging my whole setup and these made it stupidly easy to break down and rebuild clean.

These brackets lock my modular rack together with zero wobble, and the Series 4000 option matched my existing uprights perfectly. They took about ten minutes to bolt on, and now I can load up the arms without worrying about the whole setup shifting.

Installed these brackets last weekend to reinforce a wobbly bookshelf, and the fit was spot-on without any extra drilling. At this price, the thick metal construction feels surprisingly solid.
