Unfortunately Crash Blocks
aren't yet available to the general public. If you have a more than
general interest in this product you should mention it to suppliers
when you are discussing your shower door requirements with them.
Many suppliers are not aware
of Crash Blocks and your sharing the information could stimulate
interest that could, in turn, make them available to the public.
There are very descriptive and printable
drawings on this website that can aid you in this. Please feel
free to contact me with any questions
or comments.
