I've used these in a couple different settings now, which have helped a hardwired reader that was struggling to communicate in an elevator, as well as exterior readers that were overheating. I'm extremely happy that this was a cost effective solution for these problems.
This spacer was the perfect solution to mount our reader that was having communication issues in an elevator cab and obviously hid the space and screws mounting the reader. Very appreciative that ID Enhancements was able to ship this quickly while we were in a pinch. Thanks to all!
