Marine Grade stainless steel brackets w/hardware to mount radio/CB/?

Description

These were made locally by a hardware/space equipment manufacturer- they stopped production and these were the remaining inventory.  See photos for size, etc.  They are brand new and in their plastic packaging. Have at least this many, but if you need more I can look in the storage area.  Have sold many of them and people have been satisfied.
Bracket size:  base 2 1/4" by 7/8"
height:  2" to highest point by 2" wide at the base
bracket is a 90 degree angle.
Comes with hardware shown 4 of each item.
Please ask questions before buying and see photos for details.
I am not a boat owner so I am basing this description on others who have attested that these are good for marine activity.
