Gravity SP WMBS 20 B

Used four of these in an install of four The Box CL108's - nice solid construction, good locking for setting final angle and sturdy safety chain point - given the construction of the arm, it would be more likely that the mechanical fastening to the wall would fail before the hanging point itself but that's just a general observation about installation.

Would highly recommend for this purpose, naturally consult all weights and sizes of the items you intend to hang before committing to buy.
