Review on KENUCO 19 Inch Steel Hinged Extendable Wall Mount Bracket Network Equipment Rack (4U Hinged-Extendable) by John Souza

This is a good solid wall stand with good quality and stable performance (I bought 12 of them and none had any problems). A couple of minor issues to note: 1) Threads are inconsistent - depth adjustment bolts/holes are M4 and front rack bolt holes are 10-32. Why not use the imperial metric OR instead of a mix? Who knows. doesn't matter unless you're trying to screw the M5 rack screw into the front panel. 2) The adjustment screws on the sides require a larger support washer than supplied; The one on the screws is small enough that it looks like it can easily bend through the depth adjustment slot. I removed all the bolts and added a #6 washer to them and then reassembled it. 3) Apparently the rear bolt spacing is 15.5 inches, not 16 inches as is standard for US bolt spacing. I went into the concrete build so didn't actually measure/confirm it as I didn't care (I set to 1/4" full thread through the wall with washers/nuts on each side of the wall).
