This is the Bumper for the NetCam.  Some photographers are using multiple Bumpers so we make them available here.  This is a nicely finished black anodized 10 mm square aluminum part,  5 inches long.  There are four threaded holes (M5 x .8) for attachments.  Two screws and washers are included.
 
The Bumper can be adjusted up and down and provides additional protection for cameras on net backstops. Two screws lock the Bumper tight and the whole NetCam becomes even more rigid.
