Never been opened. 5 of the same model in black. Sell all for $100 or $25 each. Ordered from amazon but because of covid never used them for an installation in a public gallery. Can't return it anymore so I need to sell them. Please find the link below for specs and pricing: *Please note that I can't answer questions about how to install etc. as I've never actually opened the boxes :) https://www.amazon.ca/AboveTEK-Rotating-Brackets-Horizontal-Vertical/dp/B0747X4P7K/ref=asc_df_B0747X4P7K/?tag=googlemobshop-20&linkCode=df0&hvadid=341630215392&hvpos=&hvnetw=g&hvrand=17932029145026846646&hvpone=&hvptwo=&hvqmt=&hvdev=m&hvdvcmdl=&hvlocint=&hvlocphy=9001607&hvtargid=pla-569789276128&psc=1
