The SSE adapter for bump keys was specially developed for the GO Plug Spinner. If you turn the cylinder core with a bump key and pull back the bolt in the lock, you may need to be able to turn it further to pull back the latch and so open the door from the outside. To avoid having to turn the cylinder core again by bumping it, use the innovative SSE Plug Spinner Adapter for bump keys.
The SSE snap-on adapter can be quickly mounted with a magnet attachment and without tools.
